Chlorinated water causes severe birth defects

Chlorinated water drinking during pregnancy can a child with serious birth defects, such as heart disease and brain lead born, say British scientists at the University of Birmingham. Experts examined data on 400 thousand babies to find out how. Eleven most common birth defects with high, medium or low in chemicals that appear in the chlorination of drinking water Chlorination - fairly common method of disinfecting drinking water. But one of the disadvantages of this process is the formation of by-products, most of which are so-called trihalomethanes, including chloroform, dichlorobrommethane dibromochlormethane and bromoform are. The study showed that high chlorination increased by-products from 50 to 100% risk of malformations three: septal between the ventricles (the hole in the septum between the ventricles of the heart, which leads to the mixture of arterial and venous blood and chronic lack of oxygen) , called a cleft palate, and anentsefalii (complete or partial absence of the skull and bones of a summary of the brain). According to experts, the biological mechanisms that lead to birth defects, still unknown. But the results of the study not only further proof that chlorination may cause birth defects, but it also shows that the presence of the by-products may be associated with some specific error, the scientists said.
