Effect of Ozone and Chlorine on 3,4-Benzopyrene during the Disinfection of Water (Deystviye Ozona i Khlora na 3,4-Benzpiren pri Obezzarazhivanii Vody).

摘要

Z.P. Fedorenko's experiments showed that the tarry substances isolated from sewage possess carcinogenic activity when applied to the skin and that peroral administration to white rats of water containing various concentrations of 3-4-benzopyrene induces malignant and benign tumors of the forestomach. The frequency of tumor development was found to be directly related to the amount of the substance administered. In the light of the foregoing, it seemed worthwhile to trace the fate of 3-4-benzopyrene dissolved in water and subjected to different kinds of treatment in drinking water supply systems. The subject is inadequately discussed in the literature. There are only a few reports on the effect of chlorination of water on 3-4-benzopyrene dissolved in it. Because of the limited information on the subject, we decided to compare the effect of chlorine to that of the most intensive oxidizing agent, ozone, on 3-4-benzopyrene dissolved in water.
