Residential buildings and premises must comply with sanitary rules and regulations, but a lot of provisions of sanitary and epidemiological requirements for living conditions contradict Federal legislation and do not provide for the regulation of public relations arising in the process of ensuring sanitary and epidemiological well-being of population at all stages of arranging residential buildings and premises, therefore they require updating. International, national regulatory legal acts of a number of countries, regulatory legal acts of Russian Federation, establishing sanitary and epidemiological requirements for living conditions in residential buildings and premises, research studies carried out in Russia and abroad were used as research materials. A set of general scientific research methods: analytical, system-structural, comparative was a procedural basis of the study. Widening of the scope of sanitary standards and rules: extension of responsibility for compliance with the requirements of the document to the executive authorities, expanding the list of objects prohibited for allocation in residential buildings, measures to ensure a barrier-free environment for the disabled, requirements of inadmissibility of residential building destruction by mold, and others were suggested as the results of the study. Due to the fact that the problem of fresh air is common, the design indices of air and air exchange rate are proposed. Recommended changes regarding noise regulation assume the elimination of contradictions when correction coefficients are applied. Conclusions. Analysis of current sanitary and epidemiological requirements enabled to specify indoor environmental factors of the living space, originating from an interaction of outdoor environment, indoor environment of the living space and direct effect of the human himself and on which favorable living conditions depend, and elaborate on the reasons of violations of the established requirements. Suggested changes and additions corresponded to the main trends existing in international practice are aimed at specifying the provisions of the document, optimizing a number of standards, and eliminating contradictions. It is noted that regulation and monitoring of dwelling condition cannot be limited just by the indoor premises of the building. It is necessary to consider the living environment as a united system: human - residential unit (apartment, room, and auxiliary facilities) - building - surrounding grounds- microdistrict - residential area of the city.

Introduction. The development of the construction industry is accompanied by the use of new technologies and building materials. Materials based on mineral wool (MW) became to be widely used. The article presents the results of the study of working environment factors and the determination of the safe for health work experience based on the health risk calculation for workers in contact with MW. Material and methods. To quantify the air pollution of the working area at the construction site, samples were taken using an aspirator and a dust meter. An absorption method using a spectrophotometer was used to determine the chemical composition of the dust. Statistical analysis and mathematical modeling were carried out using a standard software package Microsoft Excel, STADIA. Results. A table for the rapid health risk assessment of workers in contact with MW was developed. The risk of health loss is determined as “High” (R = 11.3). Discussion. Working conditions under the performance of heat-insulating works at facades cladding with the use of MW are classified as harmful (class 3.2) on the dust content in working zone air. In the course of the study, coarse dust and fine dust were found in the air. The data on the change of the dust concentration depending on air humidity, the concentration of dust particles of different dispersion at different distances from the place of work is presented. The chemical composition of dust is presented, the presence of heavy metals is established. Dependences for the determination of safe for health work experience under the influence of the various concentration of dust and the duration of contact are constructed. Сonclusions. On the basis of the research to improve the legal support in the field of occupational health and safety, a number of activities for workers engaged in work with the use of MW are proposed.

Introduction. Urban wastewater sludge (UWS) is an important by-product of traditional urban wastewater treatment. Incineration is considered the most effective and universal method of reducing the volume of a large amount of UWS and their disinfection. However, the situation in the areas where the USW incineration plants are located, as a result of the pyrolytic process products entering the atmospheric air, creates complete uncertainty and unpredictability of the development of events that can lead in certain situations to the formation of an additional risk to public health. The purpose of the study. Hygienic characteristics of wastewater sludge incineration technology based on indicators of atmospheric air pollution and the magnitude of the risk to the health of the population living in the zone of influence of the implemented technology. Materials and methods. At the first stage, the analysis of the information presented in the international databases PubMed, Scopus, and PRINCE was carried out. Based on the results of the analysis, a list of chemical compounds was formed to identify the qualitative composition and determine the amount of pollutants in industrial emissions into the atmospheric air during the implementation of wastewater sludge incineration technology. Sanitary and chemical studies of industrial emissions into the atmospheric air were carried out by the chemical analytical center “Arbitration” of the D.I. Mendeleev Institute for Metrology. Modern high-precision analytical methods have been used to identify and quantify priority atmospheric pollutants. Results. Industrial emissions samples laboratory studies were carried out. Measurement results analysis showed that the indicators of quantitative emissions of harmful (polluting) substances do not exceed the international regulations requirements, most are below the detection limit, and the calculated concentrations do not exceed hygienic standards. The assessment of carcinogenic health risk are determined as acceptable, the probability of developing diseases additional cases from exposure to all the studied carcinogens throughout life in the population permanently residing in the territory in the area of the enterprise location is assessed as insignificant (less than one case). Limitations. In this study, there was a limitation associated with the method for determining concentrations of substances detection limit, which, nevertheless, satisfies the purpose of the study. Since a sample of unknown composition was taken, the entire possible substances spectrum in the emissions was evaluated. Substances with a carcinogenic effect were present in the emissions, but only those substances that had a carcinogenic potential factor were included in the carcinogenic risk assessment.
