Another angle by which to bash coal?

These things like global warming are legitimate concerns, but they need solid science behind them instead of altered science to fit a preconceived theory.

The angle is not new however coal plants account for 1% of the global pool, most of that is deposited outside of the US.
http://www.epa.gov/camr/factsheetfin.html
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.

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.

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.


It's a global issue, even with the new mercury regulations here in the US they expect a 1 to 10 percent reduction in deposition rates in the US which may increase the average IQ by 2/1000 of one point.

That's because they need a lot heat.... which comes from coal.

17th paragraph

"This mixture is then sent to massive kilns—some as long as football fields—which reach temperatures of at least 2,500 degrees F. During heating, the limestone is chemically transformed into "clinker," pebble-like pellets that are mixed with a little gypsum and ground into the fine flour we know as cement. The process releases large quantities of carbon dioxide and—in the case of Durkee—vast amounts of mercury vapor. Mercury is also released from the coal burned as fuel in the kiln, but the amount is minuscule compared to what's baked out of the limestone."

Some limestone has large amounts of mercury in it.
