Recently a study conducted by the National Institutes of Health has concluded that common air pollutants (such as ozone and fine particles) may lead to an increased risk of early pregnancy loss. Of the 343 couples studied who achieved pregnancy, 97 (28%) experienced an early pregnancy loss--all before 18 weeks. The couples with higher exposure to ozone were 12% more likely to experience an early pregnancy loss, whereas couples exposed to particulate matter (small particles and droplets in the air) were 13% more likely to experience a loss. It is suspected that increased inflammation of the placenta and oxidative stress may be what are impairing fetal development, but the research is still ongoing.
