· Components of air pollution may increase the risk of stillbirth.21 December 2012
Pregnant women exposed to higher concentrations of common air pollutants may be at increased risk of stillbirth. A study from New Jersey found that elevated levels of nitrogen dioxide, which is emitted by vehicles and power plants, increased the risk of stillbirth by 16 percent during the first trimester and 27 percent for the whole pregnancy. Similar links were found to sulfur dioxide. This is one of just a few studies to look at the association between air pollution and fetal death.
