Researchers in California, USA, claims to have found a link between autism and the pollution caused by vehicles on the highway.
The study conducted on 500 children in California says that those who are exposed to heavy pollution have the opportunity three times more likely to have autism than children who live in areas with cleaner air.
However, other researchers said the conclusion that mention pollution as a cause of autism is not enough to convince.
The findings of researchers in California have previously been featured in the journal Archives of General Psychiatry.
Researchers using data from the U.S. Environmental Protection Agency, EPA, to see the level of pollution in California.
The data they get is then used to view and compare the pollution exposure during childhood is the object of research is in the womb and when they are one year old.
Children who are the object of this study consisted of 279 individuals with autism and 245 people have developed autism.
Researchers from the University of Southern California's 0f previously been doing studies on the relationship between the occurrence of autism in those who live near major highways.
Results doubt
They warn that staying close to the source of pollution has profound implications for air pollution is widely recognized impact of time on the human nervous system.
However, the study was criticized Uta Frith who is a professor at University College London.
He doubted the existence of a direct link between air pollution and autism.
"This study does not lead us to know more about the causes autiseme because studies do not show a convincing way about how such pollutants can impact the development of the brain which then led to autism," said Frith.
Meanwhile, other researchers say, reduce pollution remains the best option at this time despite evidence showing that pollution as a cause of autism remains to be investigated further.
"However, reducing pollution arising on the highway still it's good for people's health regardless of the relationship between pollution and autism," said Sophia Xiang Sun of the University of Cambridge.
