Child’s IQ can be affected by poor air quality

A study in which mother wore personal air monitors during pregnancy has concluded that those that were exposed to poor air quality had children with IQ scores that were 4 points lower than those less exposed.

This research clearly shows the detrimental effects of poor air quality. The pollutants in this test were known as polycyclic aromatic hydrocarbons (PAH). PAH is released from burning of fossil fuels like coal, and gas, and even tobacco.

The study was done by a component of the US Environmental Protection Agency.
