MBL, WOODS HOLE, MASS.–Exposure to arsenic in drinking water at the level the U.S. Environmental Protection Agency (EPA) currently deems as safe in the United States (10 parts per billion) induces adverse health outcomes in pregnant and lactating mice and their offspring, concludes a study led by Joshua Hamilton of the Marine Biological Laboratory (MBL) and Courtney Kozul-Horvath at Geisel School of Medicine at Dartmouth. The team is part of the Dartmouth Superfund Research Program on Toxic Metals.

Pregnant and/or breastfeeding mothers who consumed low levels (10 ppb) of arsenic in their drinking water, the scientists found, exhibited significant disruption in their lipid metabolism, leading to diminished nutrients in their blood and in their breast milk. As a result, their offspring showed significant growth and development deficits during the postnatal period before weaning. Birth outcomes such as litter size and length of gestation were unaffected.
