Urine mercury

The human body contains about 13 mg of mercury. Mercury has two major classes of compounds, inorganic and organic. The amount of mercury ingested by mouth is mainly from the amount of mercury contained in rice and fresh fish, which is about half of the total intake. Inorganic mercury is absorbed by the intestinal tract by about 1%, while methylmercury is as high as 90%. Mercury is mainly excreted in urine and hair. Once the kidneys expel high concentrations of mercury, the kidneys are damaged. Mercury produces specific inhibition of a range of enzymes, causing these enzymes to become inactivated and poisoned. The toxicity of mercury mainly occurs in the kidney, brain, liver, lung, skin and other organs.
