Acute ingestion of toxic amounts of inorganic arsenic typically causes severe gastrointestinal signs and symptoms (e.g., vomiting, abdominal pain, and diarrhea). These signs and symptoms might lead rapidly to dehydration and shock. Different clinical manifestations might follow, including dysrhythmias (prolonged QT, T-wave changes), …

Boreholes sunk in the 1970s to provide clean water in Bangladesh have tapped into groundwater tainted by naturally occurring arsenic. The result, according to the World Health Organization, may be the 'largest mass poisoning in history, with 35 million people at risk from cancers. As casualties of ignorance, they join a long list.

Arsenic compounds are well absorbed within 24 hours and redistributed to the liver, lungs, intestinal wall, and spleen, where they bind to the sulfhydryl groups of tissue proteins. Arsenic also replaces phosphorus in the bone where it may remain for years. Hence, chronic poisoning can be detected years after exposure has stopped.
