The Food and Drug Administration suggests that shark, swordfish, king mackerel, and tilefish contain high levels of mercury, with albacore tuna having higher levels of mercury than canned tuna, and shrimp, canned light tuna, salmon, pollock, and catfish having lower levels of mercury.

Mercury is essential to a fluorescent bulb's ability to emit light; no other element has proved as efficient. As effective as it is at enabling white light, however, mercury—sometimes called quicksilver—is also highly toxic. It is especially harmful to the brains of both fetuses and children.

Health effects of mercury exposure Elemental and methylmercury are toxic to the central and peripheral nervous systems. The inhalation of mercury vapour can produce harmful effects on the nervous, digestive and immune systems, lungs and kidneys, and may be fatal.

Certain contaminants that they've absorbed from their environment build up in the oysters' tissue, a process called bioaccumulation. For example, oyster tissue can have 50,000 to 100,000 times more methylmercury – the most toxic form of mercury — than the water that it's living in.

Virtually all water pollutants are hazardous to humans as well as lesser species; sodium is implicated in cardiovascular disease, nitrates in blood disorders. Mercury and lead can cause nervous disorders. Some contaminants are carcinogens. DDT is toxic to humans and can alter chromosomes.

They have no known health benefits, and many of them are known to be harmful. The list includes many poisons like mercury, arsenic, lead, and thallium. It includes radioactive elements: radium, uranium, polonium, plutonium, and many others. Radiation causes cancer, and even tiny amounts are potentially harmful.

Studies of healthy subjects with amalgam fillings have shown that mercury from exposure to mercury vapor bioaccumulates in certain tissues of the body including kidneys and brain. Studies have not shown that bioaccumulation of mercury from dental amalgam results in damage to target organs.
