Heavy Metals Toxicity and the Environment
Mercury is a heavy metal belonging to the transition element series of the periodic table. It is unique in that it exists or is found in nature in three forms (elemental inorganic and organic) with each having its own profile of toxicity . At room temperature elemental mercury exists as a liquid which has a high vapor pressure and is released into the environment as mercury vapor.
