The Toxins That Threaten Our Brains
The Article: The Toxins That Threaten Our Brains by James Hamblin in The Atlantic.
The Text: Forty-one million IQ points. Thatās what Dr. David Bellinger determined Americans have collectively forfeited as a result of exposure to lead, mercury, and organophosphate pesticides. In a 2012 paper published by the National Institutes of Health, Bellinger, a professor of neurology at Harvard Medical School, compared intelligence quotients among children whose mothers had been exposed to these neurotoxins while pregnant to those who had not. Bellinger calculates a total loss of 16.9 million IQ points due to exposure to organophosphates, the most common pesticides used in agriculture.
Last month, more research brought concerns about chemical exposure and brain health to a heightened pitch. Philippe Grandjean, Bellingerās Harvard colleague, and Philip Landrigan, dean for global health at Mount Sinai School of Medicine in Manhattan, announced to some controversy in the pages of a prestigious medical journal that a āsilent pandemicā of toxins has been damaging the brains of unborn children. The experts named 12 chemicalsāsubstances found in both the environment and everyday items like furniture and clothingāthat they believed to be causing not just lower IQs but ADHD and autism spectrum disorder. Pesticides were among the toxins they identified.
āSo you recommend that pregnant women eat organic produce?ā I asked Grandjean, a Danish-born researcher who travels around the world studying delayed effects of chemical exposure on children.
