Elimination of volatile pollutants from water

Several papers have dealt with the occurrence of volatile pollutants in water, air, food, blood and urine. Knowledge of the toxicity of, and long-term exposure of humans to volatile pollutants found in drinking water, food and body fluids is still limited. Toxicity in mice and rats has been investigated in several studies. Several papers indicate the carcinogenic activity of these substances. This has led both the World Health Organization and many countries to suggest maximum limits for these substances. In its guidelines for water quality, WHO has therefore recommended maximum limit concentrations for benzene, chlorinated alkanes and alkenes, chlorophenols, polynuclear aromatic hydrocarbons, trihalomethanes and pesticides. This paper is concerned with the possibility and methods of eliminating volatile organic pollutants of health significance.
