Common Organic Pollutants Linked to Neural Tube Defects

A team of medical and environmental researchers at Beijing University have confirmed the causal relationship between exposure to high levels of organic pollutants (primarily polycyclic aromatic hydrocarbons, or PAHs) by pregnant women and the occurrence of neural tube defects. Organic pollutants result from the burning of natural substances such as coal, wood, and plant matter. A similar link was found with DDT residue exposure, even thought the pesticide has been banned in China since 1982.
