“…The data obtained are nearly consistent with data from Lodygin et al (2008) exploring PAH levels (sum of 11 PAHs) in soils of Vasil'yevskiy Island in St. Petersburg). The main anthropogenic impact on soils of residential areas of the is- land was exerted by light polyarens, including two-to fourring substances (as stated by the author), the portion of which in the total content of PAHs was more than 50 %.…”

Abstract. This study explores qualitative and quantitative composition of 15 priority polycyclic aromatic hydrocarbons (PAHs) in urban soils of some parkland, residential and industrial areas of the large industrial centre of Saint Petersburg (Russian Federation) in Eastern Europe. The aim of the study was to test the hypothesis on the PAH loading differences among urban territories with different land use scenarios. Benzo(a)pyrene toxic equivalency factors (TEFs) were used to calculate BaPeq in order to evaluate carcinogenic risk of soil contamination with PAHs. Results of the study demonstrated that soils within residential and industrial areas are characterized by common loads of PAHs generally attributed to high traffic activity in the city. Considerable levels of soil contamination with PAHs were noted. Total PAH concentrations ranged from 0.33 to 8.10 mg kg−1. A larger portion of high-molecular-weight PAHs along with determined molecular ratios suggest the predominance of pyrogenic sources, mainly attributed to combustion of gasoline, diesel and oil. Petrogenic sources of PAHs have a significant portion and define the predominance of low-molecular-weight PAHs associated with petroleum, such as phenanthrene. Derived concentrations of seven carcinogenic PAHs as well as calculated BaPeq were multiple times higher than reported in a number of other studies. The obtained BaPeq concentrations of the sum of 15 PAHs ranged from 0.05 to 1.39 mg kg−1. A vast majority of examined samples showed concentrations above the safe value of 0.6 mg kg−1 (CCME, 2010). However, estimated incremental lifetime risks posed to the population through distinct routes of exposure were in an acceptable range. One-way ANOVA results showed significant differences in total PAHs and the sum of seven carcinogenic PAH concentrations as well as in levels of FLU, PHE, FLT, PYR, BaA, CHR, BbF, BaP and BPE among parkland, residential and industrial land uses, suggesting the influence of the land use factor.

“…It is believed that in the terrestrial ecosystems, benzo [a]pyrene is mainly accumulated in soils [11,18]. The soil concentrations of benzo[a]pyrene are almost always directly related to the level of technogenic chem ical impact on the environment [12,13]. This com pound rapidly dissipates and migrates in water and air; therefore, its concentration cannot be strongly related to the contamination levels.…”

Abstract-The content and individual component compositions of polycyclic aromatic hydrocarbons in polar soils of the Russian Arctic sector have been studied. The contamination of soils near research stations is identified from the expansion of the range of individual polycyclic aromatic hydrocarbons, the abrupt increase in the content of heavy fractions, and the accumulation of benzo[a]pyrene. Along with heavy hydro carbons, light hydrocarbons (which are not only natural compounds, but also components of organic pollut ants) are also accumulated in the contaminated soils. Heavy polycyclic aromatic hydrocarbons are usually of technogenic origin and can serve as markers of anthropogenic impact in such areas as Cape Sterligov, Cape Chelyuskin, and the Izvestii TsIK Islands. The content of benzo [a]pyrene, the most hazardous organic toxi cant, appreciably increases in soils around the stations, especially compared to the control; however, the level of MPC is exceeded only for the soils of Cape Chelyuskin.

“…Sources of these compounds are asphalt pavement and emissions from industries and motor vehicles (Faure et al 2000). In the recreational and residential areas (forest parks and courtyards), the organic matter usually consists of natural fractions of humus (Lodygin et al 2008); it is possible that in wet conditions (as it was in summer 2017), the fungi mycelium was an additional source of organic carbon (Prokofieva et al 2015). The increase in the C оrg content in the forest parks is caused by the decomposition of plant litter as a natural source of C оrg ; in the courtyards, it is associated with the application of organic fertilizers (Vodyanitskii 2015).…”

Road dust is a composite substance formed due to wear of different components of transport infrastructure and motor vehicles. In 2017, 214 road dust samples were collected in Moscow to analyze pH, electrical conductivity (EC), and organic carbon (Cоrg) content that controls the ability of dust to fix pollutants. The road dust was dominated by sand and silt size particles (the share of PM10 particles varies from 2.3% to 39%) and had alkaline pH (6.4–8.1), high EC (33–712 μS/cm) and Cоrg (0.17–6.7%). The road dust is alkalinized by detergents and particles formed by abrasion of roadways and blown out from construction sites. A three-fold excess of the EC over the background values (dust in parks) is mainly due to the use of the de-icing agents and roadway maintenance. But the concentration of Cоrg in the Moscow’s road dust is on average 2 times lower compared to the background values; the increased content of Cоrg in the courtyards is associated with the application of organic fertilizers. The most significant factor that determines the physicochemical properties of the dust was the type of a road. The dust on large roads including the Third Ring Road had higher pH (7.0–8.0) and EC (98–712 μS/ cm); it contained higher proportions of the fine particle-size fractions compared to other roads. The Cоrg content in the road dust was minimum on Moscow’s major radial highways due to the insignificant contribution of soil particles. The spatial trends in variability of the physicochemical properties of the dust in Moscow were not evident as they were to a large extent masked by other factors: proximity to industrial zones and large forest parks, differences in the de-icing agents used, unequal frequencies of road cleaning, and the various contribution of soil particles that vary in composition and genesis in different parts of Moscow.
