Mercury causes neurological damage, including lost IQ points, in unborn babies and young children exposed during the first few years of life. Mercury is taken up by fish and wildlife, and accumulates in the food chain. Coal-burning power plants are the largest point source category of mercury
Mercury Emissions: A Global Problem
* Mercury emitted from coal-fired power plants comes from mercury in coal, which is released when the coal is burned. While coal-fired power plants are the largest remaining source of human-generated mercury emissions in the United States, they contribute very little to the global mercury pool. Recent estimates of annual total global mercury emissions from all sources -- both natural and human-generated -- range from roughly 4,400 to 7,500 tons per year. Human-caused U.S. mercury emissions are estimated to account for roughly 3 percent of the global total, and U.S. coal-fired power plants are estimated to account for only about 1 percent.
* EPA has conducted extensive analyses on mercury emissions from coal-fired power plants and subsequent regional patterns of deposition to U.S. waters. Those analyses conclude that regional transport of mercury emission from coal-fired power plants in the U.S. is responsible for very little of the mercury in U.S. waters. That small contribution will be significantly reduced after EPA’s Clean Air Interstate Rule and Clean Air Mercury Rule are implemented.
o U.S. coal-fired power plants emit mercury in three different forms: oxidized mercury (likely to deposit within the U.S.); elemental mercury, which travels hundreds and thousands of miles before depositing to land and water; and mercury that is in particulate form.
o Because mercury can be transported thousands of miles in the atmosphere, and because many types of fish are caught and sold globally, effective exposure reduction will require reductions in global emissions.
Regulatory Impact Analysis for the Final Mercury and Air Toxics Standards
The average effect on individual avoided IQ loss in 2016 is 0.00209 IQ points, with total nationwide benefits estimated between $0.5 and $6.1 million.
Economic Valuation of Human Health Benefits of Controlling Mercury Emissions from U.S. Coal-Fired Power Plants
Changes in mercury deposition rates associated with reductions in power plant
mercury emissions are based on regional deposition modeling results from the EPA's
analysis of the Clear Skies Initiative. In its analysis, the EPA simulated current mercury
deposition rates and the changes in these rates that would result if power plants
reduced their mercury emissions from the current rate of 49 tons per year to either 26 or
15 tons per year. We used these predictions to estimate changes in deposition rates for
the freshwater regions, the Atlantic Coastal Region, and the Gulf of Mexico. Estimated
decreases range from approximately 1% to 10%. The change in deposition rates to the
All Other Waters region is assumed to be proportional to the change in total global
emissions that would result from U.S. power plant emissions reductions, which is less
than 1%.
Acid gases cause lung damage and contribute to asthma, bronchitis and other chronic respiratory disease, especially in children and the elderly. In humans, acid gases irritate the skin, eyes, nose, throat, and breathing passages. In the environment, acid rain from NOX and SO2 damages crops and forests. Coal-burning power plants are the largest point source category of hydrochloric acid in the US

Particles cause premature death and a wide range of lung and heart diseases. Particle pollution from power plants is estimated to kill approximately 13,000 people a year.

He hasn't even bothered to return and see a single response on his very important paper. Maybe he thinks he saved us from ourselves.Joined:Fri May 04, 2012 12:46 pmLast visited:Fri May 04, 2012 12:55 pm
