The association of air pollution with fetal anomalies

Abstract

Because the relationship between pollution and congenital anomalies is biologically plausible but not well explored, our aim was to examine the association between air pollution exposure in pregnancy and fetal anomalies within a publicly-insured, large inner-city population. We hypothesized that higher exposure to the air pollutant Nitrogen Dioxide (NO2) would be associated with a higher rate of major fetal anomalies.
