Dr. Kennedy Arsenic is a toxic heavy metal that forms a number of poisonous compounds. Arsenic is found in nature at low levels mostly in compounds with oxygen, chlorine, and sulfur. These are called inorganic arsenic compounds. Arsenic in plants and animals combines with carbon and hydrogen. This is called organic arsenic. Organic arsenic is usually less harmful than inorganic arsenic. Most arsenic compounds have no smell or special taste. Inorganic arsenic compounds are mainly used to preserve wood. They are also used to make insecticides and weed killers. Copper and lead ores contain small amounts of arsenic. When arsenic enters the environment, it does not evaporate. It gets into air when contaminated materials are burned. It settles from the air to the ground where it does not break down, but can change from one form to another. Most arsenic compounds can dissolve in water. Fish and shellfish build up organic arsenic in their tissues, but most of the arsenic in fish is not toxic. Exposure to arsenic can come from: breathing workplace air with sawdust or burning smoke from wood containing arsenic, ingesting contaminated water, soil, or air at waste sites, ingesting contaminated water, soil, or air near areas naturally high in arsenic. Inorganic arsenic is a human poison. Organic arsenic is less harmful. High levels of inorganic arsenic in food or water can be fatal. A high level is 60 parts of arsenic per million parts of food or water (60 ppm). Arsenic damages many tissues including nerves, stomach and intestines, and skin. Breathing high levels can give you a sore throat and irritated lungs. Lower levels of exposure to inorganic arsenic may cause: nausea, vomiting, and diarrhea, decreased production of red and white blood cells, abnormal heart rhythm, blood vessel damage, a "pins and needles" sensation in hands and feet. Long term exposure to inorganic arsenic may lead to a darkening of the skin and the appearance of small "corns" or "warts" on the palms, soles, and torso. Direct skin contact may cause redness and swelling. Arsenic is a known carcinogen. Breathing inorganic arsenic increases the risk of lung cancer. Ingesting inorganic arsenic increases the risk of skin cancer and tumors of the bladder, kidney, liver, and lung. Tests can measure a person's exposure to high levels of arsenic. Arsenic can be measured in the urine. This is the most reliable test for arsenic exposure. Since arsenic, like other heavy metals, is stored in cells, a "challenge test" with a chelating agent is required to detect high levels. Tests on hair or fingernails can measure exposure to high levels of arsenic over the past 6-12 months, however these tests are not useful for quantitative measurements of body burden. Arsenic has, historically, been a favorite form of murder. For example, Napoleon was murdered by his cook who placed a small amount of arsenic in Napoleon'a food at each meal for several months.
