Study reveals biological process of how air pollution increases premature birth risk

NEW DELHI: A study has uncovered the biological process by which pregnant women exposed to PM2.5 air pollution could be at a higher risk of premature deliveries.

Researchers from Emory University in the US analysed blood samples from 330 African American pregnant women in the Atlanta metropolitan area.

Women living in downtown and midtown neighbourhoods, where several highways intersect, had a higher level of exposure to pollution over a year, compared to those living on the outskirts of the city, the team said.
