Prenatal exposure to mercury can reduce child's IQ

NIEHS-funded researchers, collaborating with scientists from the Danish Medical Research Council and following up on earlier findings, noted cognitive deficits in 14-year-old children of Faroe Island children exposed prenatally to mercury. An earlier study funded jointly by NIEHS and the European Commission’s Climate Research Programme found in 1997 that some developmental delays in 7-year-old children whose mothers, while pregnant, consumed fish and whale tainted with methylmercury. These deficits tended to increase when adjusted for the beneficial effects of maternal intake during pregnancy.
