Mercury from Coal Ground Truth Trekking

Coal combustion is the single highest contributor in the US, responsible for almost 50% of atmospheric mercury emissions. Approximately 75 tons of mercury are present in the coal used by US coal fired power plants every year. Of this, more than 50 tons are subsequently released into the atmosphere, while the rest remains in coal combustion wastes. Mercury in the gaseous form is transported to Alaska

It is a product of the incomplete combustion of carbon and is formed in coal mines chiefly by the oxidation of coal, particularly in those mines where spontaneous combustion occurs. Black damp is an atmosphere in which a flame lamp will not burn, usually because of an excess of carbon dioxide (CO 2) and nitrogen in the air.
