Today we review research into the link between preterm births and exposure during pregnancy to Particuate Matter (PM2.5) in an urban environment. Results indicate a 19% overall increased risk with the greatest risk during the 3rd trimester of pregnancy (prior to the 37th week) Dropping PM2.5 levels to below the EPA standard of 15μg/m3 could result in a 17% improvement in the frequency of preterm births.
