Arsenic – The Invisible Toxin in Drinking Water – Interactive Research in Bangladesh

Arsenic contaminated drinking water is a global danger, but nowhere is worse affected than Bangladesh, where a third of the population is exposed to slow poisoning. Unlike other areas of the world, in Bangladesh arsenic occurs naturally in ground water. The web documentation 'Arsenic – The Invisible Toxin in Drinking Water' hears from victims. It also accompanies German scientists who are in Bangladesh working round-the-clock on a fast and inexpensive new biological test which uses luminous bacteria to prove the presence of arsenic in drinking water.
