Dirty air can cause autism
Scientists have found a connection between autism and exposure to pollutants in the air on the body during pregnancy. A study by Harvard school of public health showed that a high level of air pollution has led to the fact that the number of autistic children has doubled.
Scientists believe that the development of infantile autism contribute tiny particles that fall from the lungs into the blood. The study was published in the journal Environmental Health Perspectives. Briefly it wrote about the British news service BBC.
Experts advise pregnant women to minimize the effects on the body dirty air. Indeed, the dirty city air has a negative effect on humans. According to the world health organization, the number of fatalities associated with this problem, reaches 3.7 million per year.
Just was investigated 1767 children: of these, 245 with autism and 1,522 without.
Analyzing data on a residence moms, the scientists saw a common link between autism, dirty air. The development of the disease experts explain the released into the bloodstream of small solid particles (invisible mineral dust and other chemicals) that can cause damage to healthy cells and tissues throughout the body.
However, the conducted research allows to assert with confidence that dirty air is the cause of autism, as there may be other factors that were not taken into account by the researchers.
The development of the disease plays a big role in heredity, but obviously that is not the only important factor. Scientists are finding increasing evidence indicating the role of contaminated air in autism.
The identification of the causes of autism may help to develop preventive measures against the disease.
Earlier this year, found new evidence that autism begins in the womb with defects in the neocortex.
