Courtesy of Blacksmith Institute Advertisement The "I Trust My Legs" gold mine in Ghana is a local affair, where miners shift silt from rudimentary pits and then combine it with mercury. The element a toxic metal that can cause brain damage captures all the gold in the dirt and then, when the mixture is heated, dissipates into the air, leaving just gold bits behind.

Top of Page Air Pollution Challenges: Climate Change EPA determined in that emissions of carbon dioxide and other long-lived greenhouse gases that build up in the atmosphere endanger the health and welfare of current and future generations by causing climate change and ocean acidification.

Long-lived greenhouse gaseswhich trap heat in the atmosphere, include carbon dioxide, methane, nitrous oxide, and fluorinated gases. These gases are produced by a numerous and diverse human activities. Carbon dioxide and other greenhouse gas pollution leads to more frequent and intense heat waves that increase mortality, especially among the poor and elderly.

Those most vulnerable to climate related health effects - such as children, the elderly, the poor, and future generations - face disproportionate risks.

Studies also find that climate change poses particular threats to the health, well-being, and ways of life of indigenous peoples in the U. The National Research Council NRC and other scientific bodies have emphasized that it is important to take initial steps to reduce greenhouse gases without delay because, once emitted, greenhouse gases persist in the atmosphere for long time periods.

EPA and the National Highway and Traffic Safety Administration between and issued the first national greenhouse gas emission standards and fuel economy standards for cars and light trucks for model yearsand for medium- and heavy-duty trucks for Proposed truck standards for and beyond were announced in June EPA is also responsible for developing and implementing regulations to ensure that transportation fuel sold in the United States contains a minimum volume of renewable fuel.

Shaped by years of unprecedented outreach and public engagement, the final Clean Power Plan is fair, flexible and designed to strengthen the fast-growing trend toward cleaner and lower-polluting American energy. It also shows the world that the United States is committed to leading global efforts to address climate change.

This partnership is laid out in the Clean Power Plan. In January EPA announced a new goal to cut methane emissions from the oil and gas sector by 40 — 45 percent from levels byand a set of actions by EPA and other agencies to put the U.

In AugustEPA proposed new common-sense measures to cut methane emissions, reduce smog-forming air pollution and provide certainty for industry through proposed rules for the oil and gas industry.

The agency also proposed to further reduce emissions of methane-rich gas from municipal solid waste landfills. EPA in July finalized a rule to prohibit certain uses of hydrofluorocarbons -- a class of potent greenhouse gases used in air conditioning, refrigeration and other equipment -- in favor of safer alternatives.

Toxic Pollutants While overall emissions of air toxics have declined significantly sincesubstantial quantities of toxic pollutants continue to be released into the air. Elevated risks can occur in urban areas, near industrial facilities, and in areas with high transportation emissions.

Numerous toxic pollutants from diverse sources Hazardous air pollutants, also called air toxics, include pollutants listed in the Clean Air Act. EPA can add pollutants that are known or suspected to cause cancer or other serious health effects, such as reproductive effects or birth defects, or to cause adverse environmental effects.

Examples of air toxics include benzene, which is found in gasoline; perchloroethylene, which is emitted from some dry cleaning facilities; and methylene chloride, which is used as a solvent and paint stripper by a number of industries.

Other examples of air toxics include dioxin, asbestos, and metals such as cadmium, mercury, chromium, and lead compounds. Numerous categories of stationary sources emit air toxics, including power plants, chemical manufacturing, aerospace manufacturing and steel mills. Some air toxics are released in large amounts from natural sources such as forest fires.

Since that assessment, EPA standards have required significant further reductions in toxic emissions. Benzene and formaldehyde are two of the biggest cancer risk drivers, and acrolein tends to dominate non-cancer risks. How EPA is working with states and communities to reduce toxic air pollution EPA standards based on technology performance have been successful in achieving large reductions in national emissions of air toxics.

As directed by Congress, EPA has completed emissions standards for all major source categories, and 68 categories of small area sources representing 90 percent of emissions of 30 priority pollutants for urban areas. In addition, EPA has reduced the benzene content in gasoline, and has established stringent emission standards for on-road and nonroad diesel and gasoline engine emissions that significantly reduce emissions of mobile source air toxics.

As required by the Act, EPA has completed residual risk assessments and technology reviews covering numerous regulated source categories to assess whether more protective air toxics standards are warranted.

EPA has updated standards as appropriate. Additional residual risk assessments and technology reviews are currently underway.

EPA also encourages and supports area-wide air toxics strategies of state, tribal and local agencies through national, regional and community-based initiatives. Among these initiatives are the National Clean Diesel Campaignwhich through partnerships and grants reduces diesel emissions for existing engines that EPA does not regulate; Clean School Bus USAa national partnership to minimize pollution from school buses; the SmartWay Transport Partnership to promote efficient goods movement; wood smoke reduction initiatives; a collision repair campaign involving autobody shops; community-scale air toxics ambient monitoring grants ; and other programs including Community Action for a Renewed Environment CARE.

The CARE program helps communities develop broad-based local partnerships that include business and local government and conduct community-driven problem solving as they build capacity to understand and take effective actions on addressing environmental problems.Pollution can take many forms: the air we breathe, the water we drink, the soil we use to grow our food, the lit-up skies and even the increasing noise we hear every day can all contribute to health problems and a lower quality of life with major disruptions and effects on wildlife and ecosystems.

Water pollution is the leading worldwide cause of death and disease, e.g. due to water-borne diseases. Water Analysis of groundwater contamination may focus on soil characteristics and site geology, hydrogeology, hydrology, and .
