Compared to the older exposed to PAH concentrations are low, children who come in contact with substances in high concentrations have increased in both symptoms and the intensity of the symptoms, the lead researcher, Professor of environmental health sciences Frederica Perera, the school of public health, Columbia University said.

Professor of psychiatry Stephen Faraone, SUNY Upstate Medical University in Syracuse, New York – who verifies the results of research also said that pollution and other environmental factors likely interact with the genetic material of the baby in the womb, from which older increased ADHD risk later on.

“What this means is that when the brain is developing, the toxins alter something in the connection function or structure of the brain, directly lead to ADHD“, professor Faraone said. He stressed that the research like this prove the relationship but is not the ADHD cause and the direct impact of the relationship between air pollution and acute ADHD.

According to the center for disease control and prevention in the United States, high PAH are chemicals formed from the combustion of no coal, oil, gas, wood, kitchen garbage or organic solids. The researchers said that traffic, the fireplace and the coal-fired power plants are the main sources of PAH substances discharged.

Research conducted with more than 230 non-smoking pregnant women, in New York city and all their children. The experts evaluated the level of exposure to PAH substance by searching for this chemical in the blood of the mother and the blood from the umbilical stalk. A survey was conducted to examine the behavior of each child by parents to fill out questionnaires in order to detect the symptoms of ADHD.

The study authors found that babies born from mothers exposed to high concentrations of PAH during pregnancy have a higher incidence of children with ADHD rate 5 times higher than the mothers exposed little or no exposure to this chemical. The pregnant mothers concerned about PAH substances should avoid exposure to cigarette smoke, not burning candles or incense in the home, use exhaust fans properly when cooking. You can also use device filtering to restrict this chemical.

 

However, according to the study authors, the sources on non-toxic PAH emissions compared to air pollution. People are not even aware when their exposure to air pollution and air pollution outdoors; not only has outside of your house but also to penetrate both the internal environment.
