Production of lipophilic volatile the organohalogen materials during laboratory chlorination of the catfish waste water and polluted river water samples the from Yugoslavia

Water chlorination leads to the generation of various halogenated products of natural and waste water organic matter. In natural surface water humic matter usually makes the greatest part of the total organic matter. However , in the river watter polluted with warious organic wastes, other organic matter is also present in significant concentrations. The investigation of the relationship between the concentration of organic matter in samples of waste water andand heavily polluted river watter in Yugoslavia on one side, and the production of lipophilic volatile organohalogen materials during the process of their chlorination on the other side is described. The production of the halomethanes and other ECD response materials during the chlorination of water samples in laboratory conditions is compared with the concentrations of organic materials in water samples. From the obatained linear correlation coeficients, possibilities of predicting amounts of organohalides during the chlorination process by using several very simple methods for the organic materials estimation in the investigated water samples are discussed and compared.
