Exposure to air pollution before pregnancy linked to obesity risk in child
Greater exposure to air pollution particulate matter (PM2.5, PM10) and Nitrogen dioxide (NO2) in the three months before conception can raise the risk of childhood obesity to two years after birth, according to a study on Thursday.
