“…Benzo[a]pyrene is one of the most toxic PAHs, it has the strongest carcinogenic activity and, by the degree of its impact on the body, is attributed to the hazard class I. It is also known that mean benzo[a]pyrene concentrations exceed the maximum permissible concentrations in the Russian Federation by 3–5 times on average [ 6 ]. An analysis of the literature, including the above works, has determined the range of the PAHs that were chosen for the present study.…”

“…To date, extensive research has been carried out on degrading bacteria and the microbial communities of roadside soils and air [ 5 , 49 ]. Studies of road dust have mainly concentrated on its chemical composition and impacts, namely on the assessment of the amount and type of pollutants that are in the environment [ 6 , 7 ]. In the present work, in addition to assessing the chemical composition of the pollutants (PAHs), we also investigated the microbial community of the road dust, namely the PAH-degrading bacteria.…”

“…), and they can also be carried by the wind to other areas [ 4 ]. The pollution of ecosystems with PAHs has been studied mainly on one biotope, e.g., soil, phylloplane, or air [ 5 , 6 , 7 , 8 ]. Urban soils and plants, on the one hand, adsorb and accumulate the air pollution; on the other hand, due to their physiological functions, they contribute to its cleansing.…”

“…The investigation of the microbial communities and the search for the relationship of their composition with the PAH content are important scientific problems. In addition, the PAH concentrations in the environment have been found to vary between cities, with there being relatively high levels of them in northern cities and low concentrations of them in the south [ 6 , 31 , 32 ]. The climate–pollution interaction is influencing the microbial communities and this remains to be, still, largely overlooked.…”

Polycyclic Aromatic Hydrocarbon-Degrading Bacteria in Three Different Functional Zones of the Cities of Moscow and Murmansk

We performed a comparative study of the total bacterial communities and communities of cultivable polycyclic aromatic hydrocarbons (PAH)-degrading bacteria in different functional zones of Moscow and Murmansk that were formed under the influence of the PAH composition in road and leaf dust. The PAHs were determined by high-performance liquid chromatography (HPLC); the bacterial communities’ diversity was assessed by metabarcoding. The degraders were isolated by their direct plating on a medium with the PAHs. The PAH total quantity declined in the leaf dust from the traffic to the recreational zone. For the road dust, a negative gradient with pollution was observed for Rhodococcus and Acinetobacter degraders and for their relative abundance in the microbiome for the functional zones of Moscow. The opposite effect was observed in the Murmansk leaf dust for the Rothia and Pseudomonas degraders and in the Moscow road dust for Microbacterium. The PCA and linear regression analyses showed that the Micrococcus degraders in the dust were sensitive to anthropogenic pollution, so they can be used as a tool for monitoring anthropogenic changes in the biosphere. The data on the degraders’ and microbial communities’ diversity suggest that minor degrading strains can play a key role in PAH degradation.

Biomonitoring of polyaromatic hydrocarbon accumulation in rural gardens using lettuce plants

et al. 2020

Purpose Air pollution in settlements is one of the most important factors affecting human health. While urban gardening and the consumption of home-grown vegetables have become more and more popular, several studies establish the risk of consuming vegetables exposed to toxic air pollutants, especially polyaromatic hydrocarbons (PAHs). However, these studies mostly concern the risk in larger cities or in industrial areas while much less information is available in rural environments. Methods In our study, small settlements were selected for a pot accumulation study. Lettuce (Lactuca sativa) plants were exposed for a 2-month period; PAH concentrations were determined both from the vegetable samples and pot soils. Results In the lettuce samples, the concentration of total PAHs was in the range of 9.1 (Litér) and 185 μg/kg dry wt (Hajmáskér), in the soil samples in the range of 31.6 (Litér) and 595.1 μg/kg wt (Hárskút). Four ring PAHs showed the highest tendency to accumulate in the majority of soil samples. Conclusion PAH concentrations in some of the sampled villages were comparable to results reported from relatively polluted regions in the world. Source appointment revealed that biomass burning and fossil fuel usage were the major sources of PAHs in rural environment; in addition, the study highlighted how important it could be to analyze individual pollution sources.

The city of Nizhnevartovsk is one of the centers of oil production in Western Siberia (Russia). A survey of the contents of trace metals and metalloids (TMMs) and polycyclic aromatic hydrocarbons (PAHs) in the snow cover was conducted there. It was aimed to study insoluble particles in the snow where the predominant share of pollutants in urban areas is concentrated. In contrast to the background areas, the deposition of TMMs in Nizhnevartovsk increases by 1-2 orders of magnitude. The deposition of Co, V, Mn, and As increases by 50-93 times, and the deposition of W increases at most (by 184 times on average). Abrasion of spikes of winter tires, abrasion of metal parts of vehicles, and combustion of motor fuels cause the pollution with W, Co, and V respectively. The total content of 12 EPA PAHs in the particulate fraction of snow in the urban area averaged 148.2 ng l -1 , and the deposition rate was 17.0 µg/m 2 . In contrast to the background areas, the share of high molecular weight 5-6-ring PAHs signi cantly increases in the city, especially dibenzo(a,h)anthracene (DahA).The indicative ratios of PAHs showed that the snowpack composition was in uenced by both petrogenic and pyrogenic sources. The proportion of pyrogenic sources is the highest in the low-rise residential area due to fuel combustion to produce heat and burning of household waste. The impact of motor transport is also major and is manifested in the maximum pollution in areas of heavy tra c. No emissions of PAHs from oil spills from the nearby Samotlor oil eld have been identi ed. It is concluded that the hydrocarbon pollution of the atmosphere from the eld weakens during the winter period compared to the warm season. Application of the I geo index characterizes the majority of the studied samples as unpolluted, 24% of the observation sites are classi ed as moderately polluted, and one (4%), as highly polluted.
