Prenatal exposure to common household chemicals linked with substantial drop in child IQ

10 diciembre 2014

Children exposed during pregnancy to elevated levels of two common chemicals found in the home — di-n-butyl phthalate and di-isobutyl phthalate — had an IQ score, on average, more than six points lower than children exposed at lower levels, according to researchers. The study is the first to report a link between prenatal exposure to phthalates and IQ in school-age children. While avoiding all phthalates in the United States is for now impossible, the researchers recommend that pregnant women take steps to limit exposure by not microwaving food in plastics, avoiding scented products as much as possible, including air fresheners, and dryer sheets, and not using recyclable plastics labeled as 3, 6, or 7.
