Mercury Poisoning Overview. Mercury is an element that is found all over the earth, in soil, rocks, and water. Even trace amounts can be found in the air. The largest deposits on earth are as cinnabar (mercuric sulfide).Mercury exists in several forms such as a liquid metal (quicksilver), as a vapor, and in compounds (organic and inorganic).ome elemental and chemical forms of mercury (vapor, methylmercury, inorganic mercury) are more toxic than other forms. The human fetus and medically compromised people (for example, patients with lung or kidney problems) are the most susceptible to the toxic effects of mercury.
