Mercury in the Air

Many people have heard about the dangers of eating fish contaminated with mercury, but not everyone realizes that one of the ways mercury gets in the atmosphere is through coal-fired power plants.

Coal-fired power plants utilize a highly charged electric field, with the help of an electrostatic precipitator (ESP), to trap ash and other particulates. This keeps the amount of ash escaping from the plant very low. However, mercury is found in coal, and the ESPs are less adept at capturing it.
