WashU Study: Drinking-Water Disinfectants Linked to Preterm Deliveries

Pregnant women who drink water with some disinfectant by-products during the second trimester have a higher risk for preterm delivery (PTD), according to a new study from the Brown School at Washington University in St. Louis.  Researchers examined records of about 600,000 births in Massachusetts from 1996-2004, and the exposure of mothers to several disinfection byproducts. They found an increased risk for PTD associated with haloacetic acids and bromodichloromethane exposures. They also found mean birth weight deficits associated with brominated trihalometanes exposures.
