They came to that conclusion after analyzing data from a nationwide sample of 116,430 nurses participating in the Nurses' Health Study II, an on-going survey that began in 1989. Among the volunteers, 325 had children with autism, and most of them lived in areas with higher levels of pollutants than those who didn't have children affected by the developmental disorder.
