Researchers placed pregnant rats and their offspring in two chambers, one exposed to outdoor air and the other containing an air filter that removed most of the air pollution particles.

After 19 days, according to the findings, lungs and livers of pregnant rats exposed to the polluted air were heavier and showed increased tissue inflammation.

The results of this study are consistent with other studies that show air pollution induces oxidative stress and inflammation in the organs and circulatory system.

The findings also echo previous studies linking air pollution with increased insulin resistance and altered fat tissue.
