Summary. Introduction: As the most important environmental factor having multiple effects on human vital activities and health, drinking water often becomes the subject of predicting adverse health effects. With the purpose of establishing quantitative and/or qualitative characteristics of harmful effects of drinking water chemicals for human health, an integral assessment of drinking water quality with subsequent health risk assessment is carried out. It is based on estimating the risk posed by chronic (carcinogenic and non-carcinogenic) exposures that shows probability of developing a disease. Results: Practical activities of departments and institutions of the Federal Service for Surveillance in the Sphere of Consumers Rights and Human Wellbeing (Rospotrebnadzor) on assessing health effects of environmental factors have demonstrated that, even in concentrations equaling their detection limits in quite a number of test methods, most chemical water pollutants pose unacceptable carcinogenic and non-carcinogenic risks both for the general population and occupational cohorts. Thus, the results of some laboratory methods of testing are inappropriate for an objective human health risk assessment. Conclusions: We describe criteria for selecting methods of the quantitative chemical analysis of drinking water fit for the purposes of sanitary and epidemiologic expert examination combined with a population health risk assessment. The criteria of choice have been elaborated based on the review of regulatory and method documents and results of analytical testing of drinking water quality.

Abstract Water pollution in China has not only become one of the most vital factors impeding the social-economic development but also threatening people's health. In this study, Kaifeng was considered as an example, and the human health risk of drinking water pathway from 2010 to 2017 was evaluated on the basis of drinking water hygiene standards and the human health risk assessment model (HHRA). Besides, the human health loss caused by water pollution was quantitatively evaluated through an emergy theory and analysis method. The results showed that the carcinogenic annual risk of carcinogenic pollutants ranged from 2.0 × 10−5 to 6.5 × 10−5, and the average health risk of non-carcinogenic pollutants was about 1.5 × 10−8, but the difference between different pollutants was obvious. Affected by water quality, social-economic development, Medicare, etc., the value of human health loss ranked at the top in 2016 with 8.73 × 1018 sej, equivalent to 9.33 million RMB, while in other years, it was around 6 × 1018 sej. It is indicated that among the factors, water quality is the direct inducement of healthy loss, the socio-economic development is the leading force effecting the value, and the Medicare is the final determinant of the public burden.

The quality of drinking water and its health implications for school children were examined at schools in the Santarém region, Amazon, Brazil. In this region, the population is fully supplied by groundwater from the voluminous Alter do Chão aquifer. Drinking water samples from three schools in Santarem city and from one school at the rural Mojuí dos Campos town were subjected to microbiological and physicochemical compositional analyses. The health risk of human exposure to chemical compounds through water intake was also evaluated. The results indicated that most water samples were contaminated with total coliform and with E. coli, which could cause serious intestinal disorders for school children. Drinking water was acidic and most of the chemical element concentrations were within Brazilian water potability recommended levels. One exception was the high aluminium content in schools from Santarem served by shallower wells, suggesting that further epidemiological studies are necessary and the monitoring of exposed school children should not be discarded. Elevated nitrate concentrations were also noted in schools from Santarém with shallower wells, indicating lack of sanitation and the importance of periodic monitoring of drinking water to prevent adverse health effects. Quantification of human health risk indicated a hazard in schools served by shallower wells, with aluminium as the main pollutant, followed by nitrate. The results showed that most drinking water quality parameters are in accordance with Brazilian legislation. However, microbiological contamination, water acidity, aluminium and nitrate concentrations must be taken into consideration for local governments in order to prevent related diseases among school children.
