Pollution Increase the Risk of Autism in Children

Autism that occurs in children is not clear cause and how to prevent it. Risks associated with autistic children, since children in the womb until the age of one year are exposed to air pollution from highways or other sources more prone to develop autism compared to children whose exposure to lower pollution. Pollution increase the risk of autism in children.

The researchers revealed that chemicals in pollutants will trigger genetic changes in the conditions of autism. Although it does not cause autism directly, but it does increase the risk.

"There is evidence that the immune system is associated with autism and pollution affected the same way," says lead researcher Heather Volk, assistant professor of the University of Southern California, in Los Angeles, USA.

In his research, Volks and his team analyzed the association between air pollution exposure in 279 children with autism were compared with 245 healthy children. The children were participating in a study on the risk of autism, genetic and environmental.

To measure the high pollution exposure in children, the researchers interviewed their mothers. While air pollution levels of water quality data obtained from the U.S. Environmental Protection Agency.

Children who are exposed to high levels of pollution in the womb for two times greater risk of suffering from autism compared with children whose exposure is low. Meanwhile, children are exposed to pollutants from birth until the age of one year, mainly highway pollution, three times greater risk of developing autism.

Strongest relation to nitrogen dioxide is suspected or known to the smog (fog containing air pollutant).

Toxins from the environment that causes abnormalities in the function of the immune system that is associated with autism. According to Geraldine Dawson, an expert on autism, some research shows people with autism find any abnormal immune system.
