The pollution caused by traffic is injurious to our health, we all know that. But a shocking study has revealed that apart from causing several negative effects, the exhaust smoke is also responsible for increasing the risk of autism in young children.
The study was conducted by the University of Southern California Keck School of Medicine (USC). It collected the data from 279 autism affected children and from 279 normal children, analyzed and compared it.
Data from the Environmental Protection Agency (EPA) was also gathered and they also conducted traffic simulations to find out how much pollution was recorded at the places where the children lived.
And finally, it was concluded that the child living closer to a busy freeway is prone to autism. However, the researchers are still to ascertain whether there is a direct connection between autism and pollution.
