High exposure to air pollution has now been linked to an increased risk of congenital malformations, according to a study published in Environmental Research.
This nationwide study is the first to assess the association between different modes of conception- assisted reproductive technology (ART) versus spontaneous conception (SC), and the risks of exposure to air pollution to each.
The researchers analyzed data on 216,730 born in Israel between 1997 and 2004, and assessed every woman for the effects of exposure to air pollution during both the first trimester and the entire pregnancy. Air pollution data i.e. sulfur dioxide (SO2), particulate matter (PM10), nitrogen oxides (NOX), and ozone (O3), were obtained from air monitoring stations for the study period.
Thus, the researchers suggest that exposure to higher levels of air pollution during pregnancy is associated with various adverse pregnancy outcomes.
