The Environmental Protection Agency estimates crematoriums emit 320 pounds of mercury per year, while activists say the real figure could be as high as three tons.

Even the higher figure is a tiny share of the more than 100 tons of mercury pumped into the atmosphere in the U.S. each year, mainly from coal-fired power plants and other industrial sources.


So according to those figures, coal burning power plants are a much greater concern. Luckily there are no coal plants where I am now but I think there was plenty where I used to live in PA.
