e.g. diesel used in extracting and transporting coal
Coal and coal waste products (including fly ash, bottom ash and boiler slag) release approximately 20 toxic-release chemicals, including arsenic, lead, mercury, nickel, vanadium, beryllium, cadmium, barium, chromium, copper, molybdenum, zinc, selenium and radium, which are dangerous if released into the environment. While these substances are trace impurities, enough coal is burned that significant amounts of these substances are released.
During combustion, the reaction between coal and the air produces oxides of carbon, including carbon dioxide (CO2, an important greenhouse gas), oxides of sulfur (mainly sulfur dioxide, SO2), and various oxides of nitrogen (NOx). Because of the hydrogenous and nitrogenous components of coal, hydrides and nitrides of carbon and sulfur are also produced during the combustion of coal in air. These include hydrogen cyanide (HCN), sulfur nitrate (SNO3) and other toxic substances. You guys do not miss health deals that is valid at http://paylesswithcoupons.com/
