Arsenic is a naturally occurring, gray metallic element that is found in the environment in combination with other elements. The periodic table symbol is As.
Arsenic compounds are usually white or colorless and do not evaporate. They have no smell and usually no taste.
How does arsenic get into the environment?
Arsenic gets into the air from industries that burn and release arsenic compounds. Also, the wind blows naturally occurring arsenic from the soil into the air.
It dissolves in water and can settle on the ground.
Commercially, arsenic is used as a wood preservative and in pesticides and herbicides.
How could I be exposed to arsenic?
People can be exposed to arsenic from:
Water or food grown in your soil if you live in an area with unnaturally elevated levels of arsenic or near a hazardous waste site.
Inhaling or ingesting arsenic dust if you work in the copper or lead smelting industries.
Sawdust or smoke from working with or burning arsenic treated wood.
Working or living in a building that uses pesticides that contain arsenic.
How can arsenic affect me?
Exposure to elevated levels of arsenic may cause:
Irritation of the stomach and intestines, leading to pain, nausea, vomiting and diarrhea;
Abnormal heart rhythm;
Nerve damage;
Corns or warts on the skin, which are not themselves a health concern, but can lead to cancer; and
In extremely elevated levels of exposure, lung cancer or death.
The U.S. Department of Health and Human Services has classified arsenic as a known carcinogen.
How can I tell if I have been exposed?
If you think you have been exposed to arsenic, there are tests that can measure its presence in your blood, urine, hair and fingernails.
Contact your physician to find out how to schedule a test.
