What is mercury pollution?
Mercury is a persistent, bioaccumulative, toxic pollutant. When released into the environment, it accumulates in water laid sediments where it converts into toxic methylmercury and enters the food chain.What is the source of mercury pollution in environment?
Sources of Mercury
Alkali and metal processing, incineration of coal, and medical and other waste, and mining of gold and mercury contribute greatly to mercury concentrations in some areas, but atmospheric deposition is the dominant source of mercury over most of the landscape.What is an example of mercury pollution?
Once it is released into the environment, for example through coal burning, mercury can circulate through air, land, water and animals for thousands of years. The current levels of mercury in the atmosphere are up to 500 % above natural levels.- The main source to most aquatic environments in the U.S. is from atmospheric deposition (rain, snow, dry particles). Some water bodies also receive mercury from direct discharge of industrial wastes, mining wastes, or naturally occurring mercury minerals.
