Oct. 19, 2011
AUSTIN, Texas — Pesticides and pollutants are related to a 450 percent increase in the risk of

Two of the pesticides found in high concentrations in the placentas of affected newborns and stillborn fetuses were

Strong associations were also found between spina bifida and anencephaly and high concentrations of

Spina bifida is a defect in which the backbone and spinal canal do not close before birth. Anencephaly is the absence of a large part of the brain and skull.
“Our advanced industrialized societies have unleashed upon us a lot of pollutants,” says Richard Finnell, professor of nutritional sciences and director of genomic research at the Dell Children’s Medical Center of Central Texas. “We’ve suspected for a while that some of these pollutants are related to an increase in birth defects, but we haven’t always had the evidence to show it. Here we quite clearly showed that the concentration of compounds from pesticides and coal-burning are much higher in the placentas of cases with neural tube defects than in controls.”
