Chromium 6 danger highlighted
A type of chromium highlighted in the film “Erin Brockovich” causes cancer in lab animals when they drink it in water, and it could be harmful to people, the National Institutes of Health said Wednesday.
Hexavalent chromium, also called chromium 6, already has been shown to cause lung cancer when inhaled. It is controlled by the Environmental Protection Agency as well as by states. Environmentalists have been fighting for decades for tighter limits on chromium in drinking water.
