We are testing the hypotheses that arsenic exposure from drinking water may be associated with adverse pregnancy outcomes. This hypothesis is based on the fact that arsenic is a known teratogen in animal models and that arsenic exposure may be associated with adverse neurodevelopmental effects in young children. We are conducting cross-sectional studies of 10-year-old and 6-year-old children in Araihazar, Bangladesh, a region which has a wide range of arsenic concentrations in drinking water. Our recent findings indicate that indeed, arsenic exposure is associated with cognitive deficits in 10 year-old children (Environmental Health Perspectives, in press, Sept, 2004).
