The aim of this study was to review epidemiologic evidence, provide summary risk estimates of the association between exposure to chlorination disinfection by-products (DBPs) and congenital anomalies, and provide recommendations for future studies.

Worldwide an estimated 7.9 million or more babies are born each year with a birth defect. The causes of birth defects remain largely a mystery, although a few culprits, including some environmental agents, have been identified as contributing factors.

What routes did they take?
