Environmental Factors

While the genetic contributions to the development of Autism Spectrum Disorders are significant, there are also likely to be significant environmental contributions to the development of autism.There are many chemicals which significantly increase the risk for neurodevelopmental disabilities, including lead and organophosphate insecticides.

Additionally, frequent exposure to high-production-volume (HPV) chemicals, many of which have not been tested for neurodevelopmental toxicity. A recent study that aimed to identify chemicals which were potentially toxic to the developing brain found approximately 200 chemicals that were neurotoxic to adult humans. Most of these were industrial chemicals (metals, solvents, and pesticides). They also created a list of 1000 chemicals which were found to be neurotoxic in experiments, but have not been directly examined in humans.

Causation of ASD has been found in environmental exposure to Thalidomide, Misoprostol, Valproic acid, prenatal rubella infections, and Chlorpyrifos.1
