Previous research has linked air pollution with risk of autism in children, but when it is considered too narrow scope of the study so that the researcher returned to do research with a broader scope.
"Women are too much exposed to the content of mercury in the air and diesel doubled risk for having a child with autism compared with women who live in a cleaner," said researcher Andrea Roberts of Harvard School of Public Health, as reported by the Huffington Post.
This study was conducted on women who are spread across the United States. They observed pollution levels that exist in these areas and observe pregnant women who were there. It is known that women who live in highly polluted areas are more at risk to have children with autism. Other chemicals present in air pollution such as manganese and other metals can also trigger autism risk, but the risk is not so high when compared to mercury and diesel.
Until now the cause of autism is still unknown. Researchers still assume that autism can be influenced by two factors: genetic factors and non-genetic parents such as age, complications during pregnancy, and others.
