Antimony can have beneficial effects when used for medical reasons. It has been used as a medicine to treat people infected with parasites. Lung cancer has been observed in some studies of rats that breathed high levels of antimony. No human studies are available. We don't know whether antimony will cause cancer in people.
Tests are available to measure antimony levels in the body.
Antimony can be measured in the urine, feces, and blood for several days after exposure. However, these tests cannot tell you how much antimony you have been exposed to or whether you will experience any health effects. Some tests are not usually performed in most doctors' offices and may require special equipment to conduct them. The EPA requires that discharges or spills into the environment of 5,000 pounds or more of antimony be reported. Lasting one year or more.
