Anyone can develop arsenic toxicity as a result of arsenic exposure. But certain people are more likely to be exposed to arsenic. The following factors increase your chances of being exposed to arsenic. If you have any of these risk factors, tell your doctor:
In addition, children may be more susceptible than adults to the health effects of arsenic. There is some evidence that arsenic exposure may harm pregnant women and their unborn babies.
Symptoms of acute arsenic exposure generally occur within 30-60 minutes after ingestion. These may include:
Symptoms of chronic arsenic exposure include:
In addition, people exposed to arsenic may be at a greater risk of developing heart disease.

There is no effective treatment for arsenic toxicity. There is increasing evidence that chelation therapy may benefit some people who were poisoned with arsenic. Chelation therapy involves putting a chemical, or chelating agent, into the bloodstream. The chelating agent combines with a toxin to help remove it from the body. Chelating agents may be given by pill or by injection.
If chelation is not indicated or is ineffective, your treatment will be designed to help manage and control your symptoms. Treatment may include IV hydration, for example.
