Mercury sources are quite diverse, ranging from thermometers, electric bulbs, and switches to power plants, coal fired power stations, metal smelters, gold mining and cement industry. It is also employed in some cosmetics like facial creams and dental treatments like mercury amalgam filling. A persistent pollutant, mercury is not limited to its source but it travels and is sometimes found thousands of kilometers away from the source.
