Exposure to arsenic in well water may contribute to reduced brain functioning in children, according to a new study from Maine.

The study of more than 200 children in grades 3 to 5 found that exposure to even low levels of arsenic in well water was associated with lower scores on intelligence tests by as much as 5 to 6 points, which may translate into problems in school.

Investigators led by Joseph Graziano, PhD, professor of environmental health sciences at Columbia University's Mailman School of Public Health in New York City, note that their findings in Maine build on earlier studies conducted by the same team in South Asia, and Bangladesh in particular, which showed similar results.
