title: [Arsenic as an environmental problem].
abstract: Chronic exposure to arsenic through drinking water is known in different continents. Arsenic compounds from disintegrating rock may be solubilized after reduction by organic material, and harmful concentrations of arsenic may be found in surface water as well as in water from drilled wells. Because of well drilling since the sixties in the Ganges delta numerous millions of people have been exposed to toxic amounts, and hundreds of thousands demonstrate signs of chronic poisoning. A changed water technology and chemical precipitation of arsenic in the drinking water can reduce the size of the problem, but the late sequelae i.e. malignant disease are incalculable. Indications for antidotal treatment of exposed individuals have not yet been outlined.
