While some of the compounds in the dirt and rock are the same in most coal, the carbon is combined here and there with hydrogen, oxygen, sulphur, nitrogen, phosporus and just about every other common element in small quantities. Imagine an extremely large net where the knots are carbon atoms.
Additional hazardous byproducts produced by coal-burning plants include, arsenic, chromium, cobalt, lead, manganese, zinc, radionuclides and particulate matter. Each type of coal produces different levels of these pollutants, all of which negatively impact both the environment and our health.hile that technology has in some ways benefited our society, we now recognize the ecological hazards and health risks associated with using coal as an energy source. Coal by itself is not harmful; however, the byproducts of burning coal raise serious health and environmental issues.
