The Saint Louis University School of Public Health is launching a study to look at the effects of urban air pollution on pregnant women in China.

SLU epidemiologist Zhengmin Qian says the research will track the pregnancies of 100,000 women in Wuhan, a city of nine million people in central China.

It's getting warmer in St. Louis and that means the issue of the region's air quality returns to the forefront.

Historically, the area has had pretty poor ozone levels. (Ozone is the main ingredient of urban smog that can be a significant health hazard, particularly for children with asthma.) Susannah Fuchs with the American Lung Association says the region’s air quality has gotten better but it still needs work.
