Mercury, Blood

Overview:

Mercury reaches most people through food, particularly large predatory fish such as swordfish, shark, king mackerel and some tuna, which accumulate methylmercury from their prey. Occupational and dental sources contribute in some cases. Blood mercury reflects relatively recent exposure, over roughly the past few months, and is the preferred sample for methylmercury from fish. Urine testing is used instead for inorganic and elemental mercury from industrial sources. Mercury mainly affects the nervous system, and exposure during pregnancy is a particular concern because it affects the developing brain. Results are interpreted alongside diet and occupation.
