Is it true that pollution effects IQ of unborn children?”

Boston (DbTechNo) – Results of a new study suggest that exposure to pollution can effect the IQ of young children. Breathing in toxic chemicals is very dangerous as we know, more so for young children as their brains are not fully developed. The study was carried out by researchers at the Columbia Center for Children’s Environmental Health. The study found that pregnant women exposed to pollution on a regular basis, were putting their unborn children at risk of developmental delays. The study tracked up to 249 children living in Harlem and the Bronx in New York for a 5 year period. It found that the children whose moms were exposed to the most pollution during their pregnancies, scored on average 5 points lower than children of mothers not exposed to pollution to the same extent. “These findings are of concern because these decreases in IQ could be educationally meaningful in terms of school performance,” said Frederica Perera, the study’s lead author and director of the Columbia Cente

It’s not so much a question of pollutants as it is “chemical compounds.” A great number of things can be harmful to a fetus, because the fetus and mother essentially share blood – anything that makes it into the mother’s bloodstream makes it to the fetus – and the fetus’ “filtration systems” (liver, kidneys) aren’t developed enough to deal with harmful compounds. For example, lead, or other heavy metals which are present in various concentrations in the environment are harmful to adults, often causing mental retardation, brain damage, internal organ damage, etc. These often require high exposure before any symptoms appear. With a fetus, you’re sure to cause the same sorts of damage, but the exposure threshold will be lower – it takes less of the compound to do more damage. Many chemicals present in the environment are known to cause birth defects with high enough exposure. These are known as “teratogens.” A quick google search of your area and “teratogenic environmental pollutants” or
