“…However, if the HI value exceeds 1, it indicates that there may be a non-carcinogenic health risk associated with the heavy metals. (Guo et al, 2023a;Liu et al, 2022a). Furthermore, to assess carcinogenic health risks, the incremental lifetime cancer risk (ILCR) is typically employed.…”

“…In such regions, HMs can easily enter the human body through inhalation, ingestion, and dermal absorption, making it imperative to assess the sources and associated health risks of these HMs (Meng et al, 2022;Wang et al, 2023). Furthermore, since November 2012, the Chinese government has made environmental protection a top priority, introducing green mining policies aimed at improving ecosystems and human health in affected areas (Liu et al, 2022a).…”

To conduct a precise health risk assessment of heavy metals (HMs) in soil, it is imperative to ascertain the primary sources of potential health risks. To achieve this objective, we conducted comprehensive measurements of HMs, including Al, Cd, Cr, Cu, Fe, Mn, Ni, Pb, Sb, Ti, V, and Zn, in soil extracted from the polymetallic mining area. A method combining the positive matrix factorization with the health risk assessment model was used to quantify the source-specific health risks. Results indicate that when compared to the local background values, the accumulation of Cd, Cr, Cu, Mn, Pb, Sb, and Zn in the local soil appears to be influenced by anthropogenic activities. Among these sources, local industrial-related activities contributed the largest proportion of HMs to the soil at 34.7%, followed by natural sources at 28.7%, mining and metallurgy-related activities at 28.2%, and traffic-related activities at 8.40%. Although the non-carcinogenic and carcinogenic risks associated with individual heavy metal elements were found to be below safety thresholds, the cumulative health risks stemming from total heavy metals exceeded safety limits for children. Moreover, the unacceptable health risks for children originating from industrial-related activities, natural sources, and mining and metallurgy-related activities were primarily concentrated in proximity to mining sites and industrial areas within the local region. This investigation furnishes valuable insights that can aid governmental authorities in formulating precise control policies to mitigate health threats posed by soils in polymetallic mining areas.

“…По данным научных исследований [17][18][19][20][21][22] установлено, что увеличение доли мелких частиц размером менее 2,5 мкм в воздухе при остром и хроническом воздействии оказывает большее влияние на смертность, чем увеличение доли частиц размером 10 мкм или других фракций. Основное воздействие частиц микроразмерного диапазона (PM 10 , PM 2.5 ) на организм человека обусловлено их глубоким проникновением в нижние отделы дыхательной системы, повреждением легочной ткани и попаданием в кровоток через нарушенные мембраны клеток альвеол легких, а также токсическими эффектами в зависимости от компонентного состава твердых частиц [6][7][8][9].…”

The whole complex of air protection activities has been planned in the RF with its aim to reduce levels of ambient air pollution. It is being implemented actively now and as a result the quality of the environment should improve for more than 7 million people. In this study, an algorithm has been suggested for assessing effectiveness of air protection activities. It includes six subsequent stages. The algorithm was tested at heat and power enterprises located in a region participating in the Clean Air Federal project. As a result, it was established that these enterprises were sources of potential public health risks; 70 % of them belonged to high risk categories. Until air protection activities are implemented, heat and power enterprises pollute ambient air in some areas in the city (up to 29.9 single maximum MPC; up to 6.9 average daily MPC; up to 19.0 average annual MPC), create unacceptable health risks (up to 25.8 HI for acute exposure, 22.7 HI for chronic exposure, CRT is up to 3.28∙10-4), and cause more than 87 thousand additional disease cases. Implementation of air protection activities at heat and power enterprises will reduce local levels of ambient air pollution but we still expect hygienic standards to be violated for 10 chemicals up to 3–22 MPC and high health risks are likely to persist (up to 6.5–25.5 HI for acute exposure, 11.9–22.4 HI for chronic exposure, CRT will be up to 3.28∙10-4). Effectiveness of the air protection activities planned at heat and power enterprises corresponds to the target levels of the gross pollutant emissions (reduction by 20.56 % by 2024) set within the Clean Air Federal project but it is estimated as ‘unacceptable’ as per the health harm indicator, which is additional disease cases associated with activities of these enterprises (< 20 %). It is necessary to implement additional air protection activities with respect to 12 pollutants (nitrogen dioxide, particulate matter, carbon (soot), carbon oxide, sulfur dioxide, dihydrosulfide, inorganic dust containing silicon dioxide in %: 70–20, dimethyl benzene, ethyl benzene, benzene, formaldehyde, and kerosene); to use the best available technologies with respect to the most hazardous chemicals; to monitor public health in areas with elevated health risks; to implement complex medical and preventive activities.
