Objective: to study the effect of chlorinated drinking water contaminated with organochlorine compounds on the incidence of cancer, in order to substantiate preventive measures to minimize its impact on public health.
Materials and methods. An epidemiological analysis was conducted of data on cancer incidence in the adult population of the cities of Svitlovodsk, Alexandria, Znamenka, Kropyvnytskyi of the Kirovograd region for 10 years (2006-2015). 160 samples from water supply and water networks were analyzed for the content of organochlorine compounds (OCC). Correlation, cluster and regression analysis (using STATISTICA 7.0 and Microsoft Excel programs) were used to establish the relationship between OCC and cancer incidence.
Research results. There is a steady increase in the oncological morbidity of the adult population of the region (an increase of 14,3%) with chloroform content in drinking water at a level of 2-3 MPC. Correlation analysis showed a relationship between excess chloroform content in drinking water and tumors of the stomach and colon (r=0,9, p<0,05). 170 additional cases of cancer per 100 thousand population of the region due to the long-term use of chlorinated drinking water.
Conclusions. Major cities of Kirovograd region are provided with drinking water from the Dnepr-Kirovograd pipeline with an excess of OCC, mainly chloroform (2-3 MPC). Their populations are at risk of stomach and colon cancer (r=0,9, p<0,05). Drinking water with chloroform can influence the occurrence of additional levels of cancer in the population (160 cases per 100 thousand population in men and 190 cases in women). Dozens of cases of cancer of the stomach and colon are associated with chlorinated drinking water. One of the factors for the increase in cancer incidence among the population of large cities of Kirovograd region is the contamination of drinking water with excessive amounts of chloroform. This requires the use of effective preventive measures and management decisions aimed at reducing the content of toxic OCC in drinking water and preventing their impact on public health.
