Green-collar worker

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Green-collar_worker

A green-collar worker is a worker who is employed in an environmental sector of the economy. Environmental green-collar workers (or green jobs) satisfy the demand for green development. Generally, they implement environmentally conscious design, policy, and technology to improve conservation and sustainability. Formal environmental regulations as well as informal social expectations are pushing many firms to seek professionals with expertise with environmental, energy efficiency, and clean renewable energy issues. They often seek to make their output more sustainable, and thus more favorable to public opinion, governmental regulation, and the Earth's ecology.

Green collar workers include professionals such as conservation movement workers, environmental consultants, council environmental services/waste management/recycling managers/officers, environmental or biological systems engineers, green building architects, landscape architects, holistic passive solar building designers, solar energy and wind energy engineers and installers, nuclear engineers, green vehicle engineers, "green business" owners, green vehicle, organic farmers, environmental lawyers, ecology educators, and ecotechnology workers, and sales staff working with these services or products. Green collar workers also include vocational or trade-level workers: electricians who install solar panels, plumbers who install solar water heaters, recycling centre/MRF attendants, process managers and collectors, construction workers who build energy-efficient green buildings and wind power farms, construction workers who weatherize buildings to make them more energy efficient, or other workers involved in clean, renewable, sustainable future energy development.

There is a growing movement to incorporate social responsibility within the green industries. A sustainable green economy simultaneously values the importance of natural resources and inclusive, equitable, and healthy opportunities for all communities.

In the context of the financial crisis of 2007–2008, many experts now argue that a massive push to develop renewable sources of energy could create millions of new jobs and help the economy recover while simultaneously improving the environment, increasing labour conditions in poor economies, and strengthening energy and food security.

Al Gore Repower America

Al Gore states that economists across the spectrum — including Martin Feldstein and Lawrence Summers — agree that large and rapid investments in a jobs-intensive infrastructure initiative is the best way to revive the economy in a quick and sustainable way.

Center for American Progress

A report from the Center for American Progress concludes that a $100 billion federal investment in clean energy technologies over 2009 and 2010 would yield 2 million new U.S. jobs, cutting the unemployment rate by 1.3% and put the nation on a path toward a low-carbon economy. The report, prepared by the Political Economy Research Institute at the University of Massachusetts Amherst, proposes $50 billion in tax credits for energy efficiency retrofits and renewable energy systems; $46 billion in direct government spending for public building retrofits, mass transit, freight rail, smart electrical grid systems, and renewable energy systems; and $4 billion for federal loan guarantees to help finance building retrofits and renewable energy projects. The Center believes that clean energy investments would yield about 300,000 more jobs than if the same funds were distributed among U.S. taxpayers. The clean energy investments would also have the added benefits of lower home energy bills and reduced prices for non-renewable energy sources, due to the reduced consumption of those energy sources.

Worldwatch Institute/UNEP

Global efforts to tackle climate change could result in millions of "green" jobs over the coming decades, according to a 2008 study prepared by the Worldwatch Institute with funding from the United Nations Environment Programme (UNEP). The study found that the global market for environmental products and services is projected to double from $1.37 trillion per year at present to $2.74 trillion by 2020, with half of that market in efficient energy use. In terms of energy supply, the renewable energy industry will be particularly important. Some 2.3 million people have found renewable energy jobs in recent years, and projected investments of $630 billion by 2030 would translate into at least 20 million additional jobs.

U.S. Conference of Mayors

Also in 2008, the U.S. Conference of Mayors released a report that finds the U.S. economy currently generates more than 750,000 green jobs, while over the next 30 years, an emphasis on clean energy could result in a five-fold increase, to more than 4.2 million jobs. Engineering, legal, research, and consulting jobs currently dominate the green jobs in the United States and could grow by 1.4 million by 2038, while renewable electricity production will create 1.23 million jobs, alternative transportation fuels will add 1.5 million jobs, and building retrofits will create another 81,000 jobs. The report notes that most of today's jobs are in metropolitan areas, led by New York City; Washington, D.C.; Houston, Texas; and Los Angeles, California.

Green-Collar Work in China

Background

In China, green-collar work is defined as “employment in industries, professions, departments and enterprises that on an average social level have low input, high output, low consumption, low emissions, recyclability, and are sustainable". With this definition, the main goal of green-collar work is to increase productive efficiency while minimizing resources used in production, including energy, while being environmentally conscious. This framework for green development maintains the current Chinese economic paradigm that has prioritized economic growth. As a general rule, green jobs include jobs in low-carbon development and environment protection. For some examples: environmental protection has existed in China since the 1970s, tree planting commenced in China every year since the PRC was established, and the solar power industry has been producing on a large scale since its beginning in the 1990s.

Policy decisions

Since 1979, many pieces of legislation have been passed in China regarding environmental protection, including:

Laws regarding pollution: Solid Waste Pollution Prevention and Control Law, Water Pollution Prevention and Control Law, Air Pollution Prevention Law, Water Pollution Control Regulation, The Energy Conservation Law.

Laws regarding recycling and clean production: Clean Production Promotion Law, Renewable Energy Law, Circular Economy Promotion Law.

China has also passed a number of laws for developing renewable energy and optimizing China’s energy structure, including: Energy Conservation Law, Eleventh Five-Year Plan – Outline for Economic and Social Development, Plan of Energy Efficiency and Emissions Reduction, Eleventh Five-Year Plan for Environmental Protection, National Climate Change Program, Climate Change Policies and Actions, and the New Energy Development Plan.

These policies aim to develop innovations and optimizations for various power generation technologies, including thermoelectric, hydroelectric, solar, wind, biofuel, and nuclear. In addition, the “policies promote the clean usage of coal, the use of coal-bed and coal-well gas”.

In 2007, the state council also issued the Comprehensive Plan to Save Energy and Reduce Emissions, giving 45 policy measures to save energy and reduce emissions. The measures related to technological innovation of traditional industries are as follows:

“Accelerate the desulphurization of current facilities for thermal power units, enhancing desulphurized unit’s capacity to 213 million kW. Newly built or expanded coal power plants must build desulphurized facilities and reserve places for denitration. Further promote projects in coal washing and clean-burning coal technologies. Strengthen the paper making, brewing, chemical, textile and dyeing industry’s waste water and pollution management and technological innovation”.

The Chinese government has also implemented measures to promote recycling pilot projects, achieve clean production, and reduce emissions with the Promotion of Clean Production Law, the Solid Waste Pollution Prevention Law, the Promotion of Recycling Law, Rules on Managing Daily Waste, Regulations on Recycling and Handling Electronic Products, as well issuing the Interim Provisions on Promoting Industrial Structure Adjustment, Opinions on Accelerating the Development of the Recycling Economy, Guiding Opinions on the Comprehensive Use of Resources during the Eleventh Five-Year Plan, the Notice of Energy Conservation and Emission Reductions, the Eleventh Five-Year Plan for National Environmental Protection, and Policies and Actions Addressing Climate Change, etc. Additionally, Chapter six of the Eleventh Five-Year Plan for national economic and social development describes a plan for developing China’s recycling industry, based on energy saving to mobilize the whole society to recycle.

Another policy focus for green-collar work in China lies in comprehensive resource utilization to achieve speedy development of resource utilization industries, which aims to improve the efficiency of resource use and increase usage for industrial waste.

China has also made policies to develop the environmental protection industry with the Eleventh Five-Year plan. The plan proposed to develop large-scale high efficiency clean power generating facilities and equipment for environmental protection and the comprehensive use of resources. The Plan also proposed to develop equipment manufacturing for environmental protection based on the needs of key environmental protection projects; to actively develop a service industry prioritizing environmental impact assessment, environmental project service; environmental technology research and development; and environmental venture investment.

The Chinese government has also set up a fund for environmental management and supported a number of key projects in ecological management and pollution management through national bonds. These projects include controlling sandstorms in Beijing and Tianjin, setting up environmental protection facilities in west region, control pollution in three rivers and lakes, recycle waste water, industrialize of recycled waste and treated water, engage in environmental pollution management in Beijing, and subsidize programs that benefit forest ecology.

Subsidies have also been introduced to facilitate the growth of green-collar work. These subsidies include electricity price subsidies for desulphurization processes, ecological construction projects (such as climate adaptation measures), clean production projects, environmental research, and production of eco-friendly projects.

China has introduced numerous tax policies to encourage green-collar work. First, the government has introduced tax policies that waives and reduces value-added tax (VAT) for enterprises that comprehensively use resources, that recycle and on-sell waste materials, that buy in waste and recycled products, that create clean energy, that produce environmental protection products, and that process waste-water. For example, since 2001, administrative agencies at all levels have waived VAT for waste-water fees collected by water plants. There have also been reforms for taxes on oil products, which has the effect of encouraging development of low-consumption cars and new-energy cars. Income taxes are also waived and reduced for enterprises that use waste material as raw materials in production and that are producing environmental protection facilities and products. A tax credit for investment and accelerated depreciation policy has also been introduced for environmental protection facilities. China also introduced a resource tax in 1988 that has since been expanded to include: a carbon tax; tax refund recissions for enterprises that export resource-based products such as refined mineral products and crude oil; reductions in the tax refund rate on copper, nickel, ferroalloy, coking coal and hard coke; and reduced tax refund rate for enterprises with high energy consumption and high pollution.

Financial policies have also been enacted to promote the development of green-collar work in China. In 2007, former SEPA, in cooperation with the China People’s Bank, and CBRC issued Opinions Regarding the Implementation of Environmental Policies and Regulations requiring the People’s Bank and CBRC to work with environmental agencies to guide financial institutions at all levels to introduce different credit policies for enterprises that are forbidden, have been shut down or have restrictions. In particular new loans could not be provided for projects which have not met environmental approvals. Later that year in December 2007, the Ministry of Environmental Protection and CIRC jointly issued the Opinions Regarding Environmental Pollution Liability Insurance, formally launching the green insurance system.  

Additionally, China has put forth documents detailing their forestry plans, including: National Afforestation and Greening Plan (2016–2020), National Forest Management Plan (2016–2050), Action Plan for Climate Change in Forestry in the 13th Five-Year Plan, Action Plan for Forestry to Adapt to Climate Change (2016–2020).

Working Conditions

Workers in Green-collar jobs in China generally enjoy better job security and benefits compared to other industries due to the difficulty in outsourcing this kind of work. These benefits include housing and transportation subsidies, health checks, social security, as well as unemployment and workplace injury insurance. However, in green energy production particularly, overtime and long shifts are very common, largely due to the fact that green energy industries are growing faster than qualified labor is able to be trained. While these workers were typically compensated with overtime pay or supplementary leave, long working hours generally reduce a worker’s performance, makes them more susceptible to occupational hazards, and reduce the quality of family life. However, green energy-production work in China is generally less hazardous than non-green energy production work, such as coal mining. But there are still notable hazards associated with green-collar jobs, particularly in power generation systems, such as blade ejection, tower collapse, overheating, the use of high voltage electricity, the use of rotating machinery, working at significant heights, the handling of heavy equipment, etc.

Many workers in green energy-production jobs in China report that they belonged to labor unions, and that representatives were able to participate in companies’ management. The unions also help carry out support programs for employees, which have contributed to the stability and satisfaction of the green-energy workforce. However, it is unclear how representatives influence decisions in management, and whether or not workers’ voices can be truly reflected in the representatives, since representatives are not always produced through direct elections.  It is also worth noting that Chinese workers are not entitled to organize independent trade unions, and that all trade unions must be affiliated with the All-China Federation of Trade Unions (ACFTU), and the formation of competing unions is prohibited. Whether state or privately owned, most trade union representatives are elected by management, rather than by workers, meaning that workers’ voices often go unheard.

Current State of Green-collar jobs in China

China has been increasing investment in infrastructure and environmental protection facilities to create demand within environmental protection industries. Many recent efforts and developments in green-collar work in China have focused on the circular economy, recycling of waste materials, and eradication of high-waste and high-pollution industries. In 2004, there were 1.595 million workers employed in the environmental protection industry. Green employment still is in its early stages in China, accounting for a very little percentage of China’s workforce. The overall caliber of workers is still particularly low, and the phasing out of outdated facilities will bring about some job loss. The transformation of some jobs that come with adopting green measures will pose a new challenge to workers who will need to update their skills. Although new green jobs will be created, the number of new positions will be limited compared to the amount of displaced workers who need redeployment, and some industries will not be able to exit quickly due to obligations to redundant workers.

Forestry Industry in China

Forests are one of the most economical carbon absorbers, with huge employment opportunities in three main areas: first, forestation and reforestation, restoration of degraded forests, and developing a joint system of forestry and agriculture to improve the sustainable development of forests; second, timber production and processing; third, sectors related to forestry, such as forest-tourism, developing chemicals for forests, forest machinery, forestry food, herbal medicines, etc. In 2007, China’s total forestation was 2,680,000 hectares, with 980,000 workers registered across all natural forest conservation projects in China. At the same time, there were a total of 1,849,200 registered forestry workers across those who worked in the fields of agricultural forestry and fishery, the fields of public management and organization, in water environment and facility management, and scientific research services. According to the China Forestry Statistical Yearbook 2008, China had over 1200 forest parks, directly or indirectly creating 3.5 million jobs. The UN Food and Agriculture Organization estimates that forest restoration can create 10 million green jobs, particularly in organic farming and biofuel production.

Forestry efforts have received criticisms for being ineffective and even exacerbating desertification and other ecological problems. Many afforestation efforts have relied on monoculture style planting of trees, without taking local ecology into account, in a style called δΈ€εˆ€εˆ‡ (yi1dao1qie1), or “cutting everything with the same knife”. Monoculture afforestation has a few problems ecologically: first, that monoculture trees act as natural pumps that deplete groundwater and intensifies desertification; second, that monoculture manufactures a homogenized landscape that has little regenerative capacity; and third, that monoculture forests are vulnerable to disease and makes for a poor wildlife habitat.

Climate Analysis

With power generation being a large source of emissions and inefficiency, China’s push to develop renewable energy and shut down ‘backward’ industry has already led to increased energy saving and emission reduction. China currently plans to accelerate this change to renewable energy, with the goal of having renewable energy sources supplying 40% of China’s energy by 2050. Additionally, forestry efforts in China have contributed to soaking up carbon dioxide from the atmosphere. A 2015 study estimated that China’s forests have absorbed more than 22 Gt of carbon since 1973, which is equal to roughly seven years of carbon emissions. Another 2016 study estimated that carbon storage in China’s forest would reach 28 Gt by 2033, which is equal to roughly 9 years of carbon emissions. Another 2018 study also found that each year, China’s forests sequester around 5% of the country’s CO2 emissions. However, there are concerns that despite the forestry efforts, consumption patterns simply encourage deforestation of other countries, offsetting the benefits of forestry efforts in China. The increase in timber demand and food imports suggest that the environmental cost of consumption is being pushed off onto neighboring countries who don’t share the same environmental goals as China. Although it is uncertain if the push for more green-collar work will be sufficient to combat the climate crisis, it begins to move in the right direction by reducing Greenhouse gas emissions caused by burning fossil fuels.

Scientific, environmental, and health justifications for green collar jobs

The Vattenfall study found Nuclear, Hydro, and Wind to have far less greenhouse emissions than other sources represented.

The Swedish utility Vattenfall did a study of full life cycle emissions of Nuclear, Hydro, Coal, Gas, Solar Cell, Peat and Wind which the utility uses to produce electricity. The net result of the study was that nuclear power produced 3.3 grams of carbon dioxide per KW-Hr of produced power. This compares to 400 for natural gas and 700 for coal (according to this study). The study also concluded that nuclear power produced the smallest amount of CO2 of any of their electricity sources.

Claims exist that the problems of nuclear waste do not come anywhere close to approaching the problems of fossil fuel waste. A 2004 article from the BBC states: "The World Health Organization (WHO) says 3 million people are killed worldwide by outdoor air pollution annually from vehicles and industrial emissions, and 1.6 million indoors through using solid fuel." In the U.S. alone, fossil fuel waste kills 20,000 people each year. A coal power plant releases 100 times as much radiation as a nuclear power plant of the same wattage. It is estimated that during 1982, US coal burning released 155 times as much radioactivity into the atmosphere as the Three Mile Island incident. In addition, fossil fuel waste causes global warming, which leads to increased deaths from hurricanes, flooding, and other weather events. The World Nuclear Association provides a comparison of deaths due to accidents among different forms of energy production. In their comparison, deaths per TW-yr of electricity produced from 1970 to 1992 are quoted as 885 for hydropower, 342 for coal, 85 for natural gas, and 8 for nuclear.

While nuclear energy releases zero carbon dioxide into the atmosphere, there is dangerous waste created that needs to be contained. Until safe, permanent disposal of nuclear waste is created, society will likely remain reliant on fossil fuels. The process used to store nuclear waste has room for improvement and will likely be advanced in the future.

Other uses

"Green collar" is used in the Metal Gear franchise to refer to members of the arms industry, mercenaries, and other individuals in the private sector involved in war and military activity, notably for profit.

"Green collar" is used in the Cannabis culture to refer to a person who finds acceptance or enjoyment of cannabis culture and cannabis products. The term is a play on the traditional uses of the terms "white collar" and "blue collar," notably, to indicate that there is broad acceptance and enjoyment of cannabis culture that transcends socioeconomic stratifications.

Soil contamination

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Soil_contamination

Soil contamination, soil pollution, or land pollution as a part of land degradation is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste. The most common chemicals involved are petroleum hydrocarbons, polynuclear aromatic hydrocarbons (such as naphthalene and benzo(a)pyrene), solvents, pesticides, lead, and other heavy metals. Contamination is correlated with the degree of industrialization and intensity of chemical substance. The concern over soil contamination stems primarily from health risks, from direct contact with the contaminated soil, vapour from the contaminants, or from secondary contamination of water supplies within and underlying the soil. Mapping of contaminated soil sites and the resulting clean ups are time-consuming and expensive tasks, and require expertise in geology, hydrology, chemistry, computer modelling, and GIS in Environmental Contamination, as well as an appreciation of the history of industrial chemistry.

In North America and Western Europe the extent of contaminated land is best known, with many of countries in these areas having a legal framework to identify and deal with this environmental problem. Developing countries tend to be less tightly regulated despite some of them having undergone significant industrialization.

Causes

Soil pollution can be caused by the following (non-exhaustive list):

The most common chemicals involved are petroleum hydrocarbons, solvents, pesticides, lead, and other heavy metals.

Any activity that leads to other forms of soil degradation (erosion, compaction, etc.) may indirectly worsen the contamination effects in that soil remediation becomes more tedious.

E-waste processing in Agbogbloshie, Ghana. Improper disposal of manufactured goods and industrial wastes, often means that communities in the global south have to process goods. Especially without proper protections, heavy metals and other contaminates can seep into the soil, and create water pollution and air pollution.

Historical deposition of coal ash used for residential, commercial, and industrial heating, as well as for industrial processes such as ore smelting, were a common source of contamination in areas that were industrialized before about 1960. Coal naturally concentrates lead and zinc during its formation, as well as other heavy metals to a lesser degree. When the coal is burned, most of these metals become concentrated in the ash (the principal exception being mercury). Coal ash and slag may contain sufficient lead to qualify as a "characteristic hazardous waste", defined in the US as containing more than 5 mg/L of extractable lead using the TCLP procedure. In addition to lead, coal ash typically contains variable but significant concentrations of polynuclear aromatic hydrocarbons (PAHs; e.g., benzo(a)anthracene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(a)pyrene, indeno(cd)pyrene, phenanthrene, anthracene, and others). These PAHs are known human carcinogens and the acceptable concentrations of them in soil are typically around 1 mg/kg. Coal ash and slag can be recognised by the presence of off-white grains in soil, gray heterogeneous soil, or (coal slag) bubbly, vesicular pebble-sized grains.

Treated sewage sludge, known in the industry as biosolids, has become controversial as a "fertilizer". As it is the byproduct of sewage treatment, it generally contains more contaminants such as organisms, pesticides, and heavy metals than other soil.

In the European Union, the Urban Waste Water Treatment Directive allows sewage sludge to be sprayed onto land. The volume is expected to double to 185,000 tons of dry solids in 2005. This has good agricultural properties due to the high nitrogen and phosphate content. In 1990/1991, 13% wet weight was sprayed onto 0.13% of the land; however, this is expected to rise 15 fold by 2005. Advocates say there is a need to control this so that pathogenic microorganisms do not get into water courses and to ensure that there is no accumulation of heavy metals in the top soil.

Pesticides and herbicides

A pesticide is a substance used to kill a pest. A pesticide may be a chemical substance, biological agent (such as a virus or bacteria), antimicrobial, disinfectant or device used against any pest. Pests include insects, plant pathogens, weeds, mollusks, birds, mammals, fish, nematodes (roundworms) and microbes that compete with humans for food, destroy property, spread or are a vector for disease or cause a nuisance. Although there are benefits to the use of pesticides, there are also drawbacks, such as potential toxicity to humans and other organisms.

Herbicides are used to kill weeds, especially on pavements and railways. They are similar to auxins and most are biodegradable by soil bacteria. However, one group derived from trinitrotoluene (2:4 D and 2:4:5 T) have the impurity dioxin, which is very toxic and causes fatality even in low concentrations. Another herbicide is Paraquat. It is highly toxic but it rapidly degrades in soil due to the action of bacteria and does not kill soil fauna.

Insecticides are used to rid farms of pests which damage crops. The insects damage not only standing crops but also stored ones and in the tropics it is reckoned that one third of the total production is lost during food storage. As with fungicides, the first insecticides used in the nineteenth century were inorganic e.g. Paris Green and other compounds of arsenic. Nicotine has also been used since 1690.

There are now two main groups of synthetic insecticides:

1. Organochlorines include DDT, Aldrin, Dieldrin and BHC. They are cheap to produce, potent and persistent. DDT was used on a massive scale from the 1930s, with a peak of 72,000 tonnes used 1970. Then usage fell as the harmful environmental effects were realized. It was found worldwide in fish and birds and was even discovered in the snow in the Antarctic. It is only slightly soluble in water but is very soluble in the bloodstream. It affects the nervous and endocrine systems and causes the eggshells of birds to lack calcium causing them to be easily breakable. It is thought to be responsible for the decline of the numbers of birds of prey like ospreys and peregrine falcons in the 1950s – they are now recovering. As well as increased concentration via the food chain, it is known to enter via permeable membranes, so fish get it through their gills. As it has low water solubility, it tends to stay at the water surface, so organisms that live there are most affected. DDT found in fish that formed part of the human food chain caused concern, but the levels found in the liver, kidney and brain tissues was less than 1 ppm and in fat was 10 ppm, which was below the level likely to cause harm. However, DDT was banned in the UK and the United States to stop the further buildup of it in the food chain. U.S. manufacturers continued to sell DDT to developing countries, who could not afford the expensive replacement chemicals and who did not have such stringent regulations governing the use of pesticides.

2. Organophosphates, e.g. parathion, methyl parathion and about 40 other insecticides are available nationally. Parathion is highly toxic, methyl-parathion is less so and Malathion is generally considered safe as it has low toxicity and is rapidly broken down in the mammalian liver. This group works by preventing normal nerve transmission as cholinesterase is prevented from breaking down the transmitter substance acetylcholine, resulting in uncontrolled muscle movements.

Agents of war

The disposal of munitions, and a lack of care in manufacture of munitions caused by the urgency of production, can contaminate soil for extended periods. There is little published evidence on this type of contamination largely because of restrictions placed by governments of many countries on the publication of material related to war effort. However, mustard gas stored during World War II has contaminated some sites for up to 50 years and the testing of Anthrax as a potential biological weapon contaminated the whole island of Gruinard.

Human health

Exposure pathways

Contaminated or polluted soil directly affects human health through direct contact with soil or via inhalation of soil contaminants that have vaporized; potentially greater threats are posed by the infiltration of soil contamination into groundwater aquifers used for human consumption, sometimes in areas apparently far removed from any apparent source of above-ground contamination. Toxic metals can also make their way up the food chain through plants that reside in soils containing high concentrations of heavy metals. This tends to result in the development of pollution-related diseases.

Most exposure is accidental, and exposure can happen through:

  • Ingesting dust or soil directly
  • Ingesting food or vegetables grown in contaminated soil or with foods in contact with contaminants
  • Skin contact with dust or soil
  • Vapors from the soil
  • Inhaling clouds of dust while working in soils or windy environments

However, some studies estimate that 90% of exposure is through eating contaminated food.

Consequences

Health consequences from exposure to soil contamination vary greatly depending on pollutant type, the pathway of attack, and the vulnerability of the exposed population. Researchers suggest that pesticides and heavy metals in soil may harm cardiovascular health, including inflammation and change in the body's internal clock.

Chronic exposure to chromium, lead , and other metals, petroleum, solvents, and many pesticide and herbicide formulations can be carcinogenic, can cause congenital disorders, or can cause other chronic health conditions. Industrial or human-made concentrations of naturally occurring substances, such as nitrate and ammonia associated with livestock manure from agricultural operations, have also been identified as health hazards in soil and groundwater.

Chronic exposure to benzene at sufficient concentrations is known to be associated with a higher incidence of leukemia. Mercury and cyclodienes are known to induce higher incidences of kidney damage and some irreversible diseases. PCBs and cyclodienes are linked to liver toxicity. Organophosphates and carbonates can cause a chain of responses leading to neuromuscular blockage. Many chlorinated solvents induce liver changes, kidney changes, and depression of the central nervous system. There is an entire spectrum of further health effects such as headache, nausea, fatigue, eye irritation and skin rash for the above cited and other chemicals. At sufficient dosages a large number of soil contaminants can cause death by exposure via direct contact, inhalation or ingestion of contaminants in groundwater contaminated through soil.

The Scottish Government has commissioned the Institute of Occupational Medicine to undertake a review of methods to assess risk to human health from contaminated land. The overall aim of the project is to work up guidance that should be useful to Scottish Local Authorities in assessing whether sites represent a significant possibility of significant harm (SPOSH) to human health. It is envisaged that the output of the project will be a short document providing high level guidance on health risk assessment with reference to existing published guidance and methodologies that have been identified as being particularly relevant and helpful. The project will examine how policy guidelines have been developed for determining the acceptability of risks to human health and propose an approach for assessing what constitutes unacceptable risk in line with the criteria for SPOSH as defined in the legislation and the Scottish Statutory Guidance.

Ecosystem effects

This area is contaminated with stagnant water and refuse, making the environment unhygienic.

Not unexpectedly, soil contaminants can have significant deleterious consequences for ecosystems. There are radical soil chemistry changes which can arise from the presence of many hazardous chemicals even at low concentration of the contaminant species. These changes can manifest in the alteration of metabolism of endemic microorganisms and arthropods resident in a given soil environment. The result can be virtual eradication of some of the primary food chain, which in turn could have major consequences for predator or consumer species. Even if the chemical effect on lower life forms is small, the lower pyramid levels of the food chain may ingest alien chemicals, which normally become more concentrated for each consuming rung of the food chain. Many of these effects are now well known, such as the concentration of persistent DDT materials for avian consumers, leading to weakening of egg shells, increased chick mortality and potential extinction of species.

Effects occur to agricultural lands which have certain types of soil contamination. Contaminants typically alter plant metabolism, often causing a reduction in crop yields. This has a secondary effect upon soil conservation, since the languishing crops cannot shield the Earth's soil from erosion. Some of these chemical contaminants have long half-lives and in other cases derivative chemicals are formed from decay of primary soil contaminants.

Potential effects of contaminants to soil functions

Heavy metals and other soil contaminants can adversely affect the activity, species composition and abundance of soil microorganisms, thereby threatening soil functions such as biochemical cycling of carbon and nitrogen. However, soil contaminants can also become less bioavailable by time, and microorganisms and ecosystems can adapt to altered conditions. Soil properties such as pH, organic matter content and texture are very important and modify mobility, bioavailability and toxicity of pollutants in contaminated soils. The same amount of contaminant can be toxic in one soil but totally harmless in another soil. This stresses the need for soil-specific risks assessment and measures.

Cleanup options

Cleanup or environmental remediation is analyzed by environmental scientists who utilize field measurement of soil chemicals and also apply computer models (GIS in Environmental Contamination) for analyzing transport and fate of soil chemicals. Various technologies have been developed for remediation of oil-contaminated soil and sediments.  There are several principal strategies for remediation:

  • Excavate soil and take it to a disposal site away from ready pathways for human or sensitive ecosystem contact. This technique also applies to dredging of bay muds containing toxins.
  • Aeration of soils at the contaminated site (with attendant risk of creating air pollution)
  • Thermal remediation by introduction of heat to raise subsurface temperatures sufficiently high to volatilize chemical contaminants out of the soil for vapor extraction. Technologies include ISTD, electrical resistance heating (ERH), and ET-DSP.
  • Bioremediation, involving microbial digestion of certain organic chemicals. Techniques used in bioremediation include landfarming, biostimulation and bioaugmentating soil biota with commercially available microflora.
  • Extraction of groundwater or soil vapor with an active electromechanical system, with subsequent stripping of the contaminants from the extract.
  • Containment of the soil contaminants (such as by capping or paving over in place).
  • Phytoremediation, or using plants (such as willow) to extract heavy metals.
  • Mycoremediation, or using fungus to metabolize contaminants and accumulate heavy metals.
  • Remediation of oil contaminated sediments with self-collapsing air microbubbles.
  • Surfactant leaching
  • Interfacial solar evaporation to extract heavy metal ions from moist soilountry

Various national standards for concentrations of particular contaminants include the United States EPA Region 9 Preliminary Remediation Goals (U.S. PRGs), the U.S. EPA Region 3 Risk Based Concentrations (U.S. EPA RBCs) and National Environment Protection Council of Australia Guideline on Investigation Levels in Soil and Groundwater.

People's Republic of China

The immense and sustained growth of the People's Republic of China since the 1970s has exacted a price from the land in increased soil pollution. The Ministry of Ecology and Environment believes it to be a threat to the environment, to food safety and to sustainable agriculture. According to a scientific sampling, 150 million mu (100,000 square kilometres) of China's cultivated land have been polluted, with contaminated water being used to irrigate a further 32.5 million mu (21,670 square kilometres) and another 2 million mu (1,300 square kilometres) covered or destroyed by solid waste. In total, the area accounts for one-tenth of China's cultivatable land, and is mostly in economically developed areas. An estimated 12 million tonnes of grain are contaminated by heavy metals every year, causing direct losses of 20 billion yuan ($2.57 billion USD). Recent survey shows that 19% of the agricultural soils are contaminated which contains heavy metals and metalloids. And the rate of these heavy metals in the soil has been increased dramatically.

European Union

According to the received data from Member states, in the European Union the number of estimated potential contaminated sites is more than 2.5 million and the identified contaminated sites around 342 thousand. Municipal and industrial wastes contribute most to soil contamination (38%), followed by the industrial/commercial sector (34%). Mineral oil and heavy metals are the main contaminants contributing around 60% to soil contamination. In terms of budget, the management of contaminated sites is estimated to cost around 6 billion Euros (€) annually.

United Kingdom

Generic guidance commonly used in the United Kingdom are the Soil Guideline Values published by the Department for Environment, Food and Rural Affairs (DEFRA) and the Environment Agency. These are screening values that demonstrate the minimal acceptable level of a substance. Above this there can be no assurances in terms of significant risk of harm to human health. These have been derived using the Contaminated Land Exposure Assessment Model (CLEA UK). Certain input parameters such as Health Criteria Values, age and land use are fed into CLEA UK to obtain a probabilistic output.

Guidance by the Inter Departmental Committee for the Redevelopment of Contaminated Land (ICRCL) has been formally withdrawn by DEFRA, for use as a prescriptive document to determine the potential need for remediation or further assessment.

The CLEA model published by DEFRA and the Environment Agency (EA) in March 2002 sets a framework for the appropriate assessment of risks to human health from contaminated land, as required by Part IIA of the Environmental Protection Act 1990. As part of this framework, generic Soil Guideline Values (SGVs) have currently been derived for ten contaminants to be used as "intervention values". These values should not be considered as remedial targets but values above which further detailed assessment should be considered; see Dutch standards.

Three sets of CLEA SGVs have been produced for three different land uses, namely

  • residential (with and without plant uptake)
  • allotments
  • commercial/industrial

It is intended that the SGVs replace the former ICRCL values. The CLEA SGVs relate to assessing chronic (long term) risks to human health and do not apply to the protection of ground workers during construction, or other potential receptors such as groundwater, buildings, plants or other ecosystems. The CLEA SGVs are not directly applicable to a site completely covered in hardstanding, as there is no direct exposure route to contaminated soils.

To date, the first ten of fifty-five contaminant SGVs have been published, for the following: arsenic, cadmium, chromium, lead, inorganic mercury, nickel, selenium ethyl benzene, phenol and toluene. Draft SGVs for benzene, naphthalene and xylene have been produced but their publication is on hold. Toxicological data (Tox) has been published for each of these contaminants as well as for benzo[a]pyrene, benzene, dioxins, furans and dioxin-like PCBs, naphthalene, vinyl chloride, 1,1,2,2 tetrachloroethane and 1,1,1,2 tetrachloroethane, 1,1,1 trichloroethane, tetrachloroethene, carbon tetrachloride, 1,2-dichloroethane, trichloroethene and xylene. The SGVs for ethyl benzene, phenol and toluene are dependent on the soil organic matter (SOM) content (which can be calculated from the total organic carbon (TOC) content). As an initial screen the SGVs for 1% SOM are considered to be appropriate.

Canada

As of February 2021, there are a total of 2,500 plus contaminated sites in Canada. One infamous contaminated sited is located near a nickel-copper smelting site in Sudbury, Ontario. A study investigating the heavy metal pollution in the vicinity of the smelter reveals that elevated levels of nickel and copper were found in the soil; values going as high as 5,104ppm Ni, and 2,892 ppm Cu within a 1.1 km range of the smelter location. Other metals were also found in the soil; such metals include iron, cobalt, and silver. Furthermore, upon examining the different vegetation surrounding the smelter it was evident that they too had been affected; the results show that the plants contained nickel, copper and aluminium as a result of soil contamination.

India

In March 2009, the issue of uranium poisoning in Punjab attracted press coverage. It was alleged to be caused by fly ash ponds of thermal power stations, which reportedly lead to severe birth defects in children in the Faridkot and Bhatinda districts of Punjab. The news reports claimed the uranium levels were more than 60 times the maximum safe limit. In 2012, the Government of India confirmed that the ground water in Malwa belt of Punjab has uranium metal that is 50% above the trace limits set by the United Nations' World Health Organization (WHO). Scientific studies, based on over 1000 samples from various sampling points, could not trace the source to fly ash and any sources from thermal power plants or industry as originally alleged. The study also revealed that the uranium concentration in ground water of Malwa district is not 60 times the WHO limits, but only 50% above the WHO limit in 3 locations. This highest concentration found in samples was less than those found naturally in ground waters currently used for human purposes elsewhere, such as Finland. Research is underway to identify natural or other sources for the uranium.

The Natural Resources Defense Council (NRDC) is a United States-based 501(c)(3) non-profit international environmental advocacy group, with its headquarters in New York City and offices in Washington D.C., San Francisco, Los Angeles, Chicago, Bozeman, India, and Beijing. The group was founded in 1970 in opposition to a hydro-electric power power plant in New York.

As of 2019, the NRDC had over three million members, with online activities nationwide, and a staff of about 700 lawyers, scientists and other policy experts.

History

NRDC was founded in 1970. Its establishment was partially an outgrowth of the Scenic Hudson Preservation Conference v. Federal Power Commission, the Storm King case. The case centered on Con Ed's plan to build the world's largest hydroelectric facility at Storm King Mountain. The proposed facility would have pumped vast amounts of water from the Hudson River to a reservoir and released it through turbines to generate electricity at peak demand.

A dozen concerned citizens organized the Scenic Hudson Preservation Conference in opposition to the project, citing its environmental impact, and the group, represented by Whitney North Seymour Jr., his law partner Stephen Duggan, and David Sive, sued the Federal Power Commission and successfully achieved a ruling that groups such as Scenic Hudson and other environmentalist groups had the standing to challenge the FPC's administrative rulings. Realizing that continued environmentalist litigation would require a nationally organized, professionalized group of lawyers and scientists, Duggan, Seymour, and Sive obtained funding from the Ford Foundation and joined forces with Gus Speth and three other recent Yale Law School graduates of the class of 1969: Richard Ayres, Edward Strohbehn Jr., and John Bryson.

John H. Adams was the group's first staff member and Duggan its founding chairman; Seymour, Laurance Rockefeller, and others served as members of the board.

Position on nuclear power

In the 1970s, NRDC sought to block expansion of the Indian Point nuclear power plant in New York. It has historically until the plant's closure in 2021, sought to close the plant. NRDC has also sought to close the Diablo Canyon nuclear plant in California. In 2018, the NRDC took no position on legislative proposals in New Jersey to subsidize three of its nuclear reactors. NRDC has argued that nuclear power is not a viable energy source to mitigate climate change, arguing that it poses public health and safety risks through nuclear waste and nuclear proliferation. In 2014, NRDC president Frances Beinecke said that the NRDC could not support nuclear power because it would lose donations.

Position on solar power

In 2012, NRDC sued the federal government to stop the 663.5-megawatt Calico solar station in the Mojave Desert in California. NRDC said the solar plant would imperil protected wildlife. In 2022, NRDC supported proposals to subsidize rooftop solar power generation.

Position on hydropower

NRDC's position on hydropower is that it is not a renewable energy source. When Indian Point was scheduled for closure, NRDC held no position on a proposal to build a transmission line to Quebec to access excess hydropower while arguing, "we certainly would not be on board where [hydropower] gobbles up the space we think should be covered by true renewables".

Programs

NRDC states the purpose of its work is "safeguard the earth—its people, its plants and animals, and the natural systems on which all life depends," and to "ensure the rights of all people to the air, the water and the wild, and to prevent special interests from undermining public interests." Their stated areas of work include: "climate change, communities, energy, food, health, oceans, water, the wild".

As a legal advocacy group, the NRDC works to accomplish environmental goals by operating within the legal system to reduce pollution and protect natural resources through litigation, and by working with professionals in science, law, and policy at the national and international level. The NRDC's Center for Campaigns & Organizing (CC&O) also oversees the NRDC Action Fund, a separate 501(c)(4) nonprofit organization which engages in political and electoral activities.

NRDC published onEarth, a quarterly magazine that dealt with environmental challenges, through 2016. It was founded in 1979 as The Amicus Journal. As Amicus, it won the George Polk Award in 1983 for special interest reporting.

Staff

The council's first president was John H. Adams, who served until 2006. He was replaced by Frances Beinecke, who served as president from 2006 to 2015. The third president was Rhea Suh, who served from 2015 to 2019.

In 2020, Gina McCarthy served as the CEO and president. She previously served as the head of the Environmental Protection Agency in the Obama administration and became White House National Climate Advisor in the Biden administration in 2021. In 2021, NRDC selected Manish Bapna, formerly of the World Resources Institute, as their new president and CEO. At their web site NRDC state they have about 700 employees including scientists, lawyers, and policy advocates.

Legislation

NRDC v. U.S. EPA (1973), with David Schoenbrod caused the United States Environmental Protection Agency to begin reducing tetraethyl lead in gasoline sooner than they were going to.

NRDC opposed the Water Rights Protection Act, a bill that would prevent federal agencies from requiring certain entities to relinquish their water rights to the United States in order to use public lands.

NRDC supported the EPS Service Parts Act of 2014 (H.R. 5057; 113th Congress), a bill that would exempt certain external power supplies from complying with standards set forth in a final rule published by the United States Department of Energy in February 2014.

Effect on administrative law

NRDC has been involved in the following Supreme Court cases interpreting United States administrative law.
