“…In addition, seven CPAHs accounted for 99.0 ± 0.3%, 99.3 ± 0.3%, and 98.8 ± 0.7% of TEQ s, in road dust, green belt soil, and parking lot dust, respectively, and were therefore major TEQ contributors. Among the seven CPAHs, BaP is the most toxic PAH, characteristiced by its carcinogenicity and mutagenicity [ 51 ], DahA is predominantly produced by coal combustion [ 52 ] and had a TEF value of 1. The sum of BaP and DahA concentrations accounted for 12.2%, 11.6%, and 3.71% of 15 PAHs; however, the sum of the TEQ values of BaP and DahA accounted for 76.8%, 70.6%, and 49.8% of 15 PAHs, in road dust, green belt soil, and parking lot dust, respectively.…”

To obtain a comprehensive understanding about that occurrence, sources, and effects on human health of polycyclic aromatic hydrocarbons (PAHs) in road environmental samples from Harbin, concentrations of 32 PAHs in road dust, green belt soil, and parking lot dust samples were quantified. The total PAH concentrations ranged from 0.95 to 40.7 μg/g and 0.39 to 43.9 μg/g in road dust and green belt soil, respectively, and were dominated by high molecular weight PAHs (HMW-PAHs). Despite the content of PAHs in arterial roads being higher, the composition profile of PAHs was hardly influenced by road types. For parking lot dust, the range of total PAH concentrations was 0.81–190 μg/g, and three-ring to five-ring PAHs produced the maximum contribution. Compared with surface parking lots (mean: 6.12 μg/g), higher total PAH concentrations were detected in underground parking lots (mean: 33.1 μg/g). The diagnostic ratios of PAHs showed that petroleum, petroleum combustion, and biomass/coal combustion were major sources of PAHs in the samples. Furthermore, according to the Incremental Lifetime Cancer Risk model, the cancer risks of three kinds of samples for adults and children were above the threshold (10−6). Overall, this study demonstrated that PAHs in the road environment of Harbin have a certain health impact on local citizens.

“…Soil properties are shown in Table 6. The total PAHs content in the reference soils did not exceed 600 µg kg −1 and corresponded to the category of uncontaminated areas [26,28,67]. For Fluvisols Salic, Leptosols Rendzic Leptosols Mollic the PAHs content was at the level of the zonal Haplic Chernozem soil [33].…”

The large-scale studies of the Lower Don and the Taganrog Bay coastal zone were carried out to determine the background concentrations of polycyclic aromatic hydrocarbons (PAHs) in soils. The content of 15 priority PAHs was determined by saponification method with HPLC detection and varied widely from 77 µg kg−1 to 16,017 µg kg−1 with mean and median values of 1040 µg kg−1 and 406 µg kg−1, respectively. PAHs’ highest concentration level was observed in the soils of the Don River delta and industrial areas of Taganrog city affected by pyrogenic contamination sources. Background monitoring sites were mostly represented with hydromorphic (Fluvisols Salic and Tidalic Fluvisols) and automorphic (Rendzic Leptosols, Mollic Leptosols) soil types in the study area. The PAHs content in the soils of the background plots did not exceed 600 µg kg−1, with a share of low-molecular-weight PAHs: about 50%. Benzo(a)pyrene content did not exceed the maximum permissible concentration (20 µg kg−1), and low-molecular-weight compounds did not exceed the threshold level for the impact of polyarenes. In automorphic soils, naphthalene and phenanthrene (35–54%) dominated in the composition of the low-molecular-weight PAHs compounds, and only phenanthrene (59–70%) dominated in hydromorphic soils.

“…There are also works considering general issues involved in the study of atmospheric air pollution over the Crimean Peninsula [34,35]. Nevertheless, most of the relevant studies investigate particular aspects of pollution without considering the entire territory of the peninsula holistically [36][37][38][39][40][41]. The content of chemical elements in atmospheric precipitation is investigated in the works [42,43].…”

Unveiling Air Pollution in Crimean Mountain Rivers: Analysis of Sentinel-5 Satellite Images Using Google Earth Engine (GEE)

This article presents an assessment of atmospheric pollutant concentrations based on state-of-the-art geoinformation research methods that utilize Sentinel-5 satellite imagery, the cloud computing platform Google Earth Engine (GEE), and ArcGIS 10.8 software. The spatial distributions of some pollutants (nitrogen dioxide, sulfur dioxide, formaldehyde, carbon monoxide, methane) in the atmosphere are analyzed on the example of the basins of the Zapadnyy Bulganak, Alma, Kacha, Belbek, and Chernaya rivers on the north-western slope of the Crimean Mountains. The concentrations of the average annual and average monthly values of pollutants for each catchment area are compared. The GEE (Google Earth Engine) platform is used for extracting annual and monthly average rasters of pollutant substances, while ArcGIS is utilized for enhanced data visualization and in-depth analytical processing. Background concentrations of pollutants within protected natural areas are calculated. By comparing the spatial and temporal distribution of pollutant values with the background concentrations within these protected areas, a complex index of atmospheric pollution is constructed. The spatial and temporal variability of nitrogen dioxide (NO2) concentrations has been thoroughly examined. Based on the regression analysis (R > 0.85), the field of values of the total amount of emissions (which are analyzed for only six points in the study area and in the surrounding areas) was restored on the basis of the spatial and temporal heterogeneity of the field of distribution of nitrogen dioxide values (NO2). Since air pollution can have negative consequences, both for human health and for the ecosystem as a whole, this study is of great importance for assessing the ecological situation within the river basins of the north-western slope of the Crimean Mountains. This work also contributes to a general understanding of the problem of gas emissions, whose study is becoming increasingly relevant. The aim of this research is to assess the potential application of Sentinel-5 satellite imagery for air quality assessment and pollution analysis within the river basins of the north-western slopes of the Crimean Mountains. The significance of this study lies in the innovative use of Sentinel-5 satellite imagery to investigate air pollution in extensive regions where a regular network of observation points is lacking.
