Study finds link between autism, air pollutants - San Jose Mercury News: "Researchers have found that children who live near freeways at birth have twice the risk of autism, suggesting that environmental factors may play a role in the disorder's growing incidence.
A study by researchers at the Saban Research Institute of Children's Hospital Los Angeles found that babies who lived within 1,000 feet of a freeway, but not a major road, were at risk.
Lead researcher Helen Volk says that may be due to the type and high level of pollutants on a freeway.
The study, published in the journal Environmental Health Perspectives, looked at 304 children with autism and 259 normally developing children."
