Effects of Drinking Water Chlorine on Human Lipid and Thyroid Metabolism

摘要

A controlled metabolic trial demonstrated that chlorine in drinking water at concentrations potentially consumed by humans may raise total plasma cholesterol and serum thyroxine. The changes, however, are much smaller in magnitude than changes seen in animals and are of questionable clinical significance. Because the protocol was a pilot study in humans and was designed to maximize the chances of finding small differences, further research will be necessary to better define and confirm these results.
