Autism research is usuallyconsidered to be personal or behavioural factors, only a very small number of environmental impact studiesbe included.


"Our research is complementary to growing children suffering from autism research, and this study suggests that toxic air pollutants is one of the risk factors for autism spectrum disorders.
