The results of our study revealed regional peculiarities, which showed an excess of the share of PM10 compared to PM2.5 in the rank distribution and high concentration of soot in the level of impact on public health. It was found that the distribution in terms of contribution to the total risk value (HQ) of the main pollutants is highest in all three zones: carbon (soot), nitrogen dioxide (NO2), suspended solids (PM), where the main share is suspended particles up to 10 microns (PM10). Among the studied zones, zon...

The main aim of the work is a comparative characteristic of carcinogenic risk for the health of the adolescent and adult population from exposure to chemical contaminants on multi-environmental ingestion of chemical substances (drinking water, soil, atmospheric air, foods). A high level of total carcinogenic individual risk in the city territories under study is identified in adolescents and adults in the 2nd zone (0.00426 and 0.00298). The value of total carcinogenic risk (TCR) in the territories under study on c...

Monitoring of atmospheric air in the city of Kazan was performed based on average annual concentrations of the Air Pollution Observation Stations (APOS) of three administrations: The Federal Budgetary Healthcare Institution -Center of Hygiene and Epidemiology in RT (Tatarstan)- (FBHI -H&E Center in RT-), Ministry of Environment and Natural Resources of RT (MEPNR of RT) and Federal State Budgetary Institution -Territorial Administration for Hydrometeorological and Environmental Monitoring in RT- (FSBI -TAHEM in RT-...

Analysis of the air environment and atmospheric emissions is an efficient method for assessing the ecological situation in cities. Assessment of the chemical composition of deposit environments (soil, snow) shows long-term contamination. The snow cover (SC), being a natural accumulating plate, reflects environmental contamination with heavy metals (HM) caused by entry from various sources. The work aims to study the three-dimensional dynamics of large city contamination with HM. Sampling (in 2019 - 100, in 2020-10...
