The problem of organochlorine compounds in drinking waterin the works of the ukrainian scientists (literary review and own research)

Abstract

Objective: We analyzed the current state of the study of the problem of OCC in drinking water according to the results of research of the Ukrainian scientists. Materials and methods: We used the sources of the scientific literature on the field, experimental, toxicological and epidemiological studies of OCC in drinking water. We applied the method of theoretical analysis of the scientific information. Results: The contribution of the Ukrainian scientists into the study of the problem of organochlorine compounds in drinking water of Ukraine is shown.The spectrum and levels of volatile THM and non-volatile HAA in tap water have been established. The distictions and basic regularities of their formation at the use of different chloragents (gaseous chlorine , sodium hypochlorite, chloramine, chlorine dioxide) and removal of water pipelines at the treatment plants, influence on the process of formation of various natural and technological factors (type anddose of chloragent, concentration of organic substances, exposure, pH, temperature etc.) have been defined. The obtained findings of the research on the problem of OCC in water are new for Ukraine, they indicate a potential threat to the health of the population at the long-term consumption of drinking water contaminated with OCC in excess amount. In recent years, the first results of biomedical studies of the effects of the contaminated with OCC drinking water on the organism of the animals and human health have been obtained. Epidemiological data on the effects of long-term consumption of chlorinated drinking water with excess OCC on non-communicable morbidity are being accumulated.
