Children whose mothers during pregnancy when exposed to air pollution two times greater risk of suffering from autism compared with pregnant women who live in a clean air environment.
Fine particles released from burning, vehicle and factory smoke is harmful substances are strongly associated with autism. Thus the conclusion of research by a team from Harvard School of Public Health.
Preliminary research also found a link between pollution and autism. Including the 2010 study which states that the risk of babies with autism has doubled if the current trimester pregnant mothers living near highways are high levels of air pollution.
In a study conducted by a team from Harvard, discovered additional evidence of the link between pollution and autism. The US government discovered autism in the country increased rapidly became one of 68 children of a previous one of 150 children in 2000.
Experts believe the increase in the number describe public awareness of this growth disorders.
Although the disorder is associated with genetic improvement of this incident makes experts interested in investigating whether environmental factors play a role.
Harvard team study involving children of the 116 430 women in the Nurses' Health Study II, which began in 2989. The researchers collected data where the women were staying during pregnancy and the level of pollution. Then compared with the history of the birth of 245 children with autism and 1,522 children of normal growth. All children born between the years 1990-2002.
It turns out there is no link between autism with fine particle pollutants before or early gestational age, or after the baby is born. However, exposure to high pollution during pregnancy trimester increased the risk of autism doubled.
Unclear how the fine particles that trigger autism, but these pollutant particles covered a lot of contaminants and can enter cells that interfere with brain development of the baby.
