The National Institutes of Health (NIH), a part of the U.S. Department of Health and Human Services , is the nation’s medical research agency—making important discoveries that improve health and save lives.

Mice exposed to low doses of arsenic in drinking water, similar to what some people might consume, developed lung cancer, researchers at the National Institutes of Health have found.
Arsenic levels in public drinking water cannot exceed 10 parts per billion (ppb), which is the standard set by the U.S. Environmental Protection Agency.
Low doses of arsenic cause cancer in male mice.
“Although this is only one study, it adds to a growing body of evidence showing adverse health effects from very low exposures to arsenic, raising the possibility that no level of arsenic appears to be safe,” said Linda Birnbaum, Ph.D, director of the National Institute of Environmental Health Sciences (NIEHS) and NTP.
