Estimation of risk to health of the population at impact of water peroral factor of inhabitancy in conditions of large industrial centre for problems of socially-hygienic monitoring (on example of Perm)

Questions of the estimation of risk to health of the population at impact of the chemical substances act-ing with potable water from network of centralized economic-drinking water supply are considered. Gen-eralization and analysis of potable water quality is executed. The quantitative characteristic of cancero-genic and not cancerogenic risk for children's and adult population of city is given. The priority chemical substances forming the greatest contributions to risk of health hazard are allocated. Zoning territory of city on risk of cancerogenic and not cancerogenic impacts of chemical substances in potable water from network of economic-drinking water supply is lead. It is shown, that all children's population (more than 137 thousand people) and almost all adult population (more than 806 thousand people) in large industrial Perm city lives in conditions of negative impact of water factor of inhabitancy which defines the raised level of chronic not cancerogenic and cancerogenic risk for health.
