chds and the environment Drinking Water Contaminants and Congenital Heart Defects
Concern for exposures to drinking water contaminants and their effects on adverse birth outcomes has prompted several studies evaluating chlorination disinfection by-products and chlorinated solvents. Some of these contaminants are found to be teratogenic (cause birth defects) in animal studies. This review evaluates 14 studies on chlorination disinfection by-products such as trihalomethanes (THMs) and five studies on chlorinated solvents such as trichloroethylene (TCE). Because excess rates of Neural Tube Defects (NTDs), oral clefts, cardiac defects, and choanal atresia were found in studies of TCE- contaminated drinking water, further study was recommended.
