Doctors have found a potential cause of autism


Медики нашли потенциальную причину аутизмаBad environment and dirty air is dangerous for health.

The study focused on a group of children from Shanghai aged from zero to three years, showed that exposure to fine particles of the exhaust of cars, industrial waste and other sources of air pollution (PM2.5) increased the risk of autism is up 78% – said the author.

A group of scientists from Monash University in Australia led by associate Professor school of public health and preventive medicine Uminga Guo (Guo Yuming) first took up the question of the influence of the long-term effects of air pollution on autism in young children in a developing country. The study included 124 children with this disorder and 1240 healthy children, researchers gradually watched them for nine years and has studied the relationship between air pollution and autism spectrum disorder. The results published in the journal Environmental International.

– The causes of autism are complex and not fully understood, but the environmental factor is increasingly known among the most important, along with genetics. The developing brain of young children more vulnerable to toxic environmental influences, and in several studies it was assumed that it can affect brain function and the immune system. These effects can explain the strong correlation we found between exposure to air pollution and autism spectrum disorder, but more precisely to examine this link we will only further investigation – sure.

Air pollution is one of the main problems in the modern world and the annual cause of death to 4.2 million people (according to the world health organization). Hazardous waste provoke many diseases and deaths in China and India, especially in densely populated areas of these countries. Even in Australia, where the situation is usually better, air pollution by industrial enterprises causes about three thousand of premature deaths per year, costing the country $ 24 billion.

– Negative effects of air pollution on human health documented safe level of exposure to waste simply does not exist. Even a very small amount of harmful particles, typically associated with premature birth, delay in learning, and a number of serious diseases, including heart disease, emphasizes the scientist.

The study looked at health effects of three types of particulate matter – PM1, PM2.5 and PM10. It refers to small particles in the air, which are byproducts of emissions from factories, emissions of vehicles, construction works and road dust. The smaller the particles, the more they are able to penetrate into the lungs and bloodstream, causing a number of serious diseases.
