A coalition of the nation's experts in the domains of epidemiology, toxicology, exposure science, and a variety of specialists in medicine have published their concerns about a set of six categories of chemicals (lead, mercury, air pollutants, flame retardants, PCBs, and organo-phosphate insecticides) that play a role in causing harm to the developing brain, and play an important role in children developing intellectual disabilities, ADHD, and/or autism spectrum disorder. This work opens the door to actually reducing the chance that a child could develop one of these neurodevelopmental disorders.
