Sanitary and hygienic analysis of drinking water quality was carried out and health risk assessment of
the population living in the industrial areas of the Perm region and consuming drinking water with
high content of organochlorine compounds (Tetrachloromethane to 3.7 MPC, chloroform to 2.8 MPC).
In the conditions of oral exposure to COC in the population formed unacceptable non-carcinogenic risk
of endocrine system pathology (HI = 1.72, due to the influence of chloroform (85.7 %). In exposed
children with high concentrations of chloroform and Tetrachloromethane in the blood, endocrine system
pathology was diagnosed 2,0–2,4 times more often, the relative risk of obesity (E66.0) and redundant
power supply (E67.8) 2.4 times higher than the indicators of the comparison group. A reliable causeand–
effect relationship between the development of metabolic disorders (obesity and overweight) and the
consumption of drinking water with high content of chos (OR = 2,4; DI = 1,05–6,8) was established; the
proportion of the explained variance was R2 = 0,3–0,34; 85,4 ≤ F ≥ 112,8; p < 0,001. As features of the
development of metabolic disorders in the population for a long time consuming drinking water with
high content of chos (Tetrachloromethane, chloroform) revealed a sharp disharmony of physical
development, early formation of excess body weight and obesity, an increase of 1,4–1,6 times the level Of
C-peptide and leptin in the blood, insulin resistance index HOMA-IR, (p < 0,05).
