Living in areas with heavily polluted air can cause children schizophrenia and autism. This conclusion was made by scientists from University of Rochester (USA) under Professor Deborah Cory-Slecht, who investigated the impact of the environment on development brain of newborn mice.
Scientists have found that in those areas that people are associated with the development of autism and schizophrenia, irreparable changes.

During the experiment, the mice were exposed to air, saturated with small particles in a concentration that “corresponds to rush hour in a mid-sized American city.” Moreover, the particles were small enough so that the nose and the lungs could not filter them out. Such a mixture of animals breathed on four hours a day for eight days, equally divided between the first and second weeks of their life.
It turned out that as a result of this effect, the lateral the ventricles of the brain almost triple up against standard size, interfering with the development of other parts of the brain (and harmful effects were observed mainly in male mice).

It has also been observed that after inhaling contaminated air in glutamate increased abnormally in the brain of experimental animals the high concentration of which is typical for people suffering autism and schizophrenia. Scientists note that ventricular enlargement the brain is also associated with these two diseases.
Professor Cory-Slechta refrains from concluding that causal relationship. At the same time, the conclusions that can be do according to the results of the experiment, coincide with the results research by scientists from the University of California.

Scientists have found that children who spent the first year of their lives in areas with high levels of air pollution, three times more likely subsequently autistic than their peers who were born in more environmentally friendly settlements.
Researchers have previously linked the presence of pollutants in the air. substances with developmental disorders in living creatures of the nervous system. IN including the suggestion that life in regions with heavily polluted atmosphere causes depression and other diseases. Professor Cory-Slechta believes that following her research should raise the issue of sufficiency of existing air purity standards.
