Study links outdoor air pollution with 2.7 million preterm births per year

A new study published in the journal Environment International for the first time quantifies the global impact by combining data about air pollution in different countries with knowledge about how exposure to different levels of air pollution is associated with preterm birth rates.

It finds that in 2010, about 2.7 million preterm births globally – or 18% of all pre-term births – were associated with outdoor exposure to fine particulate matter (PM2.5 is especially harmful to human health, as it can penetrate deep inside the lungs).
