But how exactly does the mercury end up in the water to begin with? Mercury is used in a variety of products such as thermometers, pharmaceuticals, and making electrical equipment; however, the largest sources of mercury contamination come from burning coal, as well as chlorine plants, and recycling of auto metal scrap.
Mercury was found in Egyptian tombs that are from 1500 BC. Chinese people also knew it from long ago.
