Mice exposed to arsenic in drinking water developed lung cancer in a new study by researchers at the National Institutes of Health have found.

The reason they used so much is because mice need to be exposed to greater concentrations of arsenic in drinking water than humans to achieve the same biological dose and similar health effects. Arsenic in public drinking water cannot exceed 10 parts per billion (ppb) by U.S. Environmental Protection Agency regulations.
