“…Внедрение новых методов исследования факторов производственной среды приводит к изменению представлений о качестве условий труда и необходимости использования для их оценки методологии оценки риска здоровью [1][2][3]. В настоящее время выделен физико-химический фактор загрязнения воздуха рабочей зоны -аэрозоли мелкодисперсных пылевых частиц (РМ 10 и РМ 2.5 ).…”

“…Следовательно, для разработки и обоснования мероприятий, направленных на оздоровление рабочей среды, необходимо проведение оценки риска здоровью работающих, которая затруднена в результате отсутствия гигиенического норматива мелкодисперсных фракций для воздуха рабочей зоны. В связи с тем что мелкодисперсные пылевые частицы так же, как и АПФД, обладают неблагоприятными физико-химическими свойствами при действии на организм, нами для получения ориентировочных величин референтных концентраций РМ 10 и РМ 2.5 для оценки риска здоровью работающих была использована методология расчета пылевой нагрузки 3 . Сведения о действии мелкодисперсной фракции пыли на организм работающих ограничены.…”

“…В различных нормативных документах объем легочной вентиляции при выполнении нагрузки не совпадает. В связи с этим для расчета приняты численные показатели объема легочной вентиляции, учитывающие объем вентиляции для периода нахо-ждения дома (8 ч) 0,63 м 3 в час, вне дома (8 ч) -0,88 м 3 в час, на рабочем месте -1,4 м 3 в час, используемые при расчете показателей риска здоровью 3 . Число дней в году -365, число рабочих дней -250, число нерабочих дней -115.…”

In Russia there is a system for standardizing and control over aerosols with predominantly fibrogenic effects and dust particles with different structure. But at the same time there are no hygienic standards for fine-dispersed dust contents in working area air and it makes hygienic assessment of working conditions more complicated and impedes use of risk assessment methodology. Our research goal was to substantiate a concentration of aerosols containing fine-dispersed dust particles (РМ10 и РМ2.5) in working are air that were harmless for workers’ health. It was done via applying a procedure for determining dust burden and using it when calculating health risks for workers. We assessed dust content in working area air with focus on fine-dispersed dust particles РМ10 и РМ2.5 with a dust measuring device «OMPN-10.0». Chemical structure of dust particles was determined with atomic absorption procedure. Results were estimated according to HS 2.2.5.3532-18. Dust burden was calculated according to State standard GOST R 54578-2011. We established dependence between duration of working experience under exposure to fine-dispersed dust that was harmless for health and a value of excess in dust contents over the suggested concentration and work shift duration. To assess health risk for workers caused by exposure to fine-dispersed dust particles taking their chemical structure into account, we determined reference concentrations for working area air; 0.1 mg/m3 for РМ10, and 0.055 mg/m3 for РМ2.5. Use of calculated concentrations allowed suggesting models for calculating harmless duration of working experience under exposure to dusts in concentrations higher than recommended ones. The results enable substantiating organizational activities aimed at workers’ health preservation.

“…We calculated additional death cases and disease cases during 2017 caused by elevated average annual and average daily concentrations of particulate matter (РМ 2.5 ; РМ 10 ) registered at some monitoring posts 8 . Many Russian and foreign researchers state that particulate matter (РМ 2.5 , РМ 10 ) are an important indicator showing ambient air contamination and its influence on human health [4,5,8,[13][14][15][16][17].…”

The first two years of «Clean air» Federal project in Omsk have been completed and preliminary results have been estimated. The present work deals with issues related to implementation of the Complex program aimed at reducing emissions, highlights the sanitary-epidemiologic situation related to air contamination in settlements, and describes activities aimed at optimizing a laboratory network used for monitoring over ambient air quality. It is essential to obtain maximum objective data on population health risks caused by ambient air contamination at the initial stage of the Federal project implementation. Our research goal was to estimate intermediate results in the Federal project implementation taking into account preliminary analysis of sanitary epidemiologic welfare in Omsk related to ambient air contamination. Our research object was ambient air quality in Omsk, potential health risks and population health parameters associated with ambient air contamination over 2009–2019. The examination was performed in accordance with a procedure for health risk assessment under exposure to chemicals (R 2.1.10.1920-04), as well as procedures, approaches, and algorithms stipulated in the normative and methodological documents MR 2.1.6.0158-19, MR 2.1.6.0156-19, with use of geoinformation technologies and statistical procedures. The research allowed substantiating a program for monitoring over ambient air quality taking into account all the existing monitoring systems basing on spatial distribution of total hazard quotient (S) in Omsk residential area and preliminary data obtained via aggregated calculations of ground contaminants concentrations. We suggested a list of control parameters and a procedure for their estimation in order to provide objective and timely monitoring over implementation of the Complex program aimed at reducing emissions into ambient air in Omsk. Implementation of the Complex program was estimated as per results of certain activities accomplished within it in 2019.

“…New research techniques aimed at examining occupational factors are being implemented into practice; it leads to changes in concepts regarding working conditions quality and nowadays health risk assessment methodology is required to assess them [1][2][3]. At present great attention is paid to such physical and chemical factors that pollute working area air as fine-dispersed dust aerosols (РМ 10 and РМ 2.5 ).…”
