Scientific American: Associate adjunct public health professor Kim Harley comments on a new UC Davis study that has linked autism to environmental exposures to pesticides, complementing a study Professor Harley had done earlier. In 2007, she and her colleagues had found a two-fold increase in pervasive developmental disorders (the larger group to which autism belongs) among 531 children in California's Salinas Valley whose mothers' urine had higher levels of organophosphate pesticides. She says now: "The weight of evidence is beginning to suggest that mothers' exposures during pregnancy may play a role in the development of autism spectrum disorders."
