Introduction. Information on the MPC (TAC) value and the limiting hazard sign is important for the analysis of the hazard of chemicals in the water of water bodies for the health of the population, serves as the basis for the development of preventive measures to ensure safe conditions for water use by the population. For the purpose of specifying the possible adverse effects of the influence of chemicals on the hygienic conditions of water use of the population, information is needed on the entire spectrum of the effects of chemicals on water quality indicators. Materials and methods. The object of the study was indicators characterizing the effect of chemicals on the organoleptic properties of water and the general sanitary regime of water bodies, algorithms for analyzing primary data to determine threshold concentrations for the effect on odor, color, turbidity, foaming, pH, general sanitary regime of water bodies - biochemical oxygen consumption, concentration of nitrogenous connections. To organize the databases, the standard apparatus of the Excel subBD electronic tables was used. The mathematical apparatus of data analysis, grouping and selection of critical indicators of limiting signs is presented. Conclusion. It is concluded that the use of databases allows to study the relationship “concentration - effect”, increases the reliability and accuracy of substantiating the threshold concentration of pollutants in water by the influence of limiting signs of harmfulness.
Introduction. A review of the judicial practice of securing land use rights on the territory of sanitary protection zones (SPZ) of sources of centralized household drinking water supply of the population, a comparative analysis of Russian and foreign approaches to the legal regulation of sanitary protection of sources of centralized household drinking water supply (starting now - SPZ). The computational methods for assessing the spread of pollutants and determining the size of the boundaries of the 2 nd zone of the WSS for water sources, analysis of the degree of protection of aquifers of drinking water supply sources, which can become an alternative to expensive measures to prohibit economic activities in the territory of the SPZ, have been updated. The data on the water pollution of the sources of the centralized drinking water supply of the population of the Russian Federation, the Moscow River, on the effect of surface runoff polluted with persistent organic substances on the sanitary state of surface waters are presented. Material and methods. Methods of the survey, comparative analysis were applied to assess the legal regulation of sanitary protection of sources of centralized drinking water supply to the population in urbanized areas, hygienic assessment of water pollution, correlation and regression analysis. Results. The data of field studies of surface water bodies and groundwater in the Russian Federation indicate the low efficiency of wastewater treatment to ensure water quality safety in the sources of centralized drinking water supply to the population. On the one hand, the low efficiency of groundwater protection and the ability to protect groundwater due to natural conditions are shown. Judicial practice confirms the need to establish the security of a water supply source from wastewater when justifying health hazards and violations of current regulations. Conclusion. The analysis of the legal regulation of the protection of sources of centralized economic water supply to the population and treatment, wastewater disposal showed that the issues of the legal status of the territory of the SPZ of water sources are not developed. The need to standardize approaches to the organization of SPZ and the methods used to ensure the protection of sources of centralized drinking water supply to the population was not evaluated.
Актуальность. Хвостохранилища горнодобывающих предприятий являются источниками загрязнений окружающей среды химическими элементами и служат существенным фактом риска для хозяйственно-питьевого водопользования и здоровья населения. На примере воды гидроотвала на хвостохранилище в пос. Комсомольск (Кемеровская обл.), вмещающего отходы цианирования золото-арсенопирит-кварцевых руд, показано воздействие мышьяка и сурьмы на организмы теплокровных животных. Цель: обоснование маркёров мониторинга окружающей среды и теплокровных организмов в условиях риска воздействия хвостохранилища отходов обогащения сульфидных руд. Методы исследования включали в себя отбор проб воды из гидроотвала с целью перорального введения экспериментальным животным (самцы белых крыс линии Вистар с массой тела 250–290 г). Воду анализировали на ряд химических элементов методом ICP-AES. Далее после препарирования животных определяли элементный состав тканей. Анализ осуществлялся методом РФА-СИ на станции элементного анализа VEPP-3 (ИЯФ СО РАН). Обработка эмиссионных спектров производилась с помощью программы AXIL. Результаты. По данным элементного состава тканей органов – печени, почек, сердца, лёгких, щитовидной железы, крови, мочи и кала – самцов белых крыс линии Вистар обоснованы маркёры экспозиции комбинированного действия сурьмы (42–61 мкг/кг/сут) и мышьяка (10,0–15,0 мкг/кг/сут). Установлено, что воздействие сурьмы и мышьяка в исследуемых дозах приводит как к их накоплению в тканях органов животных, так и к изменению баланса Zn, Cu, Fe, Mn, Sr, Ni, Pb. Рассчитаны коэффициенты абсорбции и элиминации As и Sb для тканей внутренних органов при пероральном поступлении в организм, а также показана корреляция между содержанием As и другими элементами в органах экспериментальных животных в разные сроки эксперимента как маркёры реакции организма.
The present paper dwells on assessing oral sub-acute exposure of a warm-blooded body to non-organic compounds that contain antimony and arsenic and are introduced with drinking water. Another issue was to assess changes in their concentrations as well as concentrations of other elements in tissues of certain organs. We accomplished elemental analysis of tissues taken from exposed white Wistar rats; the analysis included the following elements: S,

Increased competition between producers has now become one of the critical features of the country’s economy. Within the framework of the Water Strategy of the Russian Federation, technological issues play a significant role both in the protection of water resources and in compliance with the safety requirements and favourable quality of the water used. For more than 20 years worldwide, there has been a transition from a hazard-oriented to a risk-oriented approach in the organization of nature and water protection activities. The use of a risk-based approach determines the mandatory monitoring of all pollutants and calculation methods for assessing various types of toxicity of a substance, their hazardous concentrations based on knowledge of the structure and information about the hazard of substances from international databases and registers. Based on the analysis of the main provisions of the Water Strategy of the Russian Federation until 2020 in conjunction with the conditions of water use affecting the health of the population, the priority problems of technological development in the water protection sector and their medical and preventive support were identified. Measures have been outlined to ensure the compliance of the technology for the protection of water bodies, sources of household and drinking water supply to the population and industrial development for monitoring the effectiveness and efficiency of hygienic regulation, sanitary and epidemiological examination of project documentation and a risk-oriented approach to ensuring the activities of business entities on the territory of sanitary protection zones of drinking water sources: water supply, wastewater treatment from point and diffuse sources of pollution.

Introduction. In 2019-2020 as part of the implementation of the “regulatory guillotine” mechanism, there was revised or canceled a number of regulatory requirements including those related to the rationing of various types of water. The purpose of the work was to eliminate outdated requirements that do not meet modern conditions for ensuring sanitary and epidemiological well-being in the field of water use of the population. Materials and methods. The research materials in the field of hygienic regulation of waters were sanitary rules and norms for drinking, domestic and cultural water use, maximum allowable concentrations (MAC) and approximate permissible levels (APL) of chemicals in the water of water bodies for domestic drinking and cultural water use. Results. There were approved two interrelated documents including SanPiN 2.1.3684-21 and SanPiN 1.2.3685-21, in which the requirements for the main types of water are systematized. The revised and updated documents exclude provisions of a descriptive nature, methods and technologies for implementing mandatory requirements. A distinctive feature of the hygienic requirements for water was the use of the error value of the method for determining substances in assessing the compliance of pollution levels with hygienic standards. Hence, the requirement for metrological support of determination methods is mandatory. The standards included in SanPiN 1.2.3685-21 are harmonized considering international data, including WHO, and health risk assessment. On the base of these approaches in section III, concerning water hygiene standards, twenty one standard was harmonized by chemical factor, of which 7 were modified, 5 standards were added considering WHO recommendations, 8 - considering EU recommendations (hormones and antibiotics), 1 - considering recommendations of Uniform sanitary rules of EurAZEU, standards of 69 pesticide active ingredients that are listed in Section IX containing pesticide guidelines were excluded. In addition, the list of APLs includes standards for 9 new substances that were reviewed and approved by the Commission on State Sanitary and Epidemiological Regulation. Limitations. The limitations of the study are related to the fact that the changes and additions made to the sanitary and epidemiological requirements for various types of waters are not exhaustive and can be revised as the standards of new substances, data on the toxicity and danger of standardized compounds, modern water treatment technologies and expansion of water uses become available. Conclusion. The implementation of the principles of elimination of excessive regulation and harmonization of standards with international requirements made it possible to unify the system of hygienic standards for various types of water.
