Ethylmercury is broken down by the body quickly and does not accumulate. Mercury also may enter water bodies through a direct discharge of industrial waste or municipal sewage. Mercury is classified as a heavy metal (atomic weight 200.59) and is well known as being among the most toxic of metals (World Health Organization, 2007). Symptoms of long-term high level methylmercury exposure include disturbances in vision, hearing and speech, as well as tingling and numbness in fingers and toes, lack of coordination and muscle weakness. You also can visit the Agency for Toxic Substances and Disease Registry at www.atsdr.cdc.gov/toxprofiles/tp46.html for a toxicological profile of mercury.
