“…In addition, compared to the PCBs substituted by the meta position of the chlorine group, the PCBs where the adjacent positions are simultaneously substituted by the chlorine group are more toxic. The ability of plants to oxidize and decompose PAHs in contaminated sites is related to PAHs structures, bioaccumulation, mobility, and degradability [100,101].…”

Polycyclic aromatic hydrocarbons (PAHs) are frequently detected in soil. Their biological toxicity and carcinogenic, teratogenic, and mutagenic effects pose a great threat to the ecological environment and human health. Firstly, the sources, physicochemical properties, and environmental hazards of PAHs are reviewed in this paper, and then their pollution status and different methods for their detection in soil are described in detail. The remediation technologies to treat pollution in the field and farmland are compared, and the technical status and factors influencing phytomicrobial remediation of PAHs in contaminated soil are evaluated in the most comprehensive way. The mechanisms of phytomicrobial remediation of PAHs-contaminated soil under different conditions are innovatively discussed. Additionally, the regulation mechanism of enzymes involved in plant and microbial degradation of PAHs in soils is studied. This is the first study on the regulation mechanism of degradation enzyme in a PAHs review. The aim of this paper is to review the pollution status, remediation technologies, mechanisms, and biodegradation actions of PAHs in soil. This review creatively provides reliable technical support for strengthening soil remediation and environmental management.

“…Chemical contamination of the soil is most often represented by a mixture of substances in inorganic and organic forms (heavy metals, petroleum hydrocarbons and polycyclic aromatic hydrocarbons) [1][2][3]. Numerous works are devoted to the analysis of the detrimental impacts of coal stations on the biological conditions of soils and ecosystems [4,5].…”

Thallium (Tl) was introduced into Haplic Chernozem in the amounts of 3, 30, and 300 mg/kg, and biological indicators were observed at 10, 30, and 90 days after incubation in the laboratory experiment. An increase in biological activities; i.e., the total number of bacteria, Azotobacter spp. abundance, enzymes (catalase, dehydrogenases), and phytotoxic indicators (germination rate of radish) after 30 days of Tl exposure were noted. The total number of bacteria and Azotobacter spp. abundance, enzyme activity, and phytotoxicity were more sensitive (16–76%) and informative (12–65%) indicators compared to the control, respectively. Integral biological indicators of soil state (IIBS) noted at 10, 30, and 90 days decreased at a dose of 30 and 300 mg/kg by 13–43% in relation to the control. An increase in Tl concentration and duration of exposure (up to 90 days) inhibited biological properties and caused ecotoxicological effects, respectively. We concluded that the use of individual indicators served as an indicator of the state of the soil.

“…Over the last three decades, PAHs pollutant has been extensively studied by different institutes due to its lifethreatening effects (Hong et al, 2020;Li et al, 2020a). PAHs pollutants adversely affect the health of humans as well as animals (Gou et al, 2020;Patel et al, 2020) and therefore, many PAHs are subject to worldwide mandatory regulations (Sushkova et al, 2019). For this reason, there is a critical need to describe the transport and fate of PAHs pollutants in the urban landscape (Sushkova et al, 2019).…”

“…One of the least understood aspects of PAHs in urban environment is the transport of such pollutants through urban fluvial systems. This makes the study of the transport and accumulation of the PAHs (Sushkova et al, 2019) in urban rivers of great importance.…”

Unraveling the Transport and Fate of Polycyclic Aromatic Hydrocarbons Through Coupling Fluvial Geomorphic Modeling and Measured Data

Coastal zones receive upstream runoff and sediments, as well as the contaminants transported with sediments and flow. Constant urban growth in many coastal areas has raised an increasing concern about stream and floodplain contamination. This is a particularly challenging issue because fluvial hydraulics in the coastal zone is complex, due to the presence of backwater (BW) conditions which alter flow patterns and sediment transport regime. Polycyclic aromatic hydrocarbons (PAHs) are persistent organic pollutants that are widely distributed in urban areas and can be transported through stormwater runoff and by sediment facilitated transport. Even though this is a widespread problem in urban areas, the relationship between fluvial deposition and concentrations of PAHs is largely uninvestigated. To fill this gap, this paper investigates the correlation between PAHs concentration and sediment deposition in a backwater zone, using the lower Darby Creek, PA as a case study. A BW geomorphologic model was used to simulate the hydraulics of the flow in Darby Creek. The model identified locations of high and low shear stresses, erosion, and deposition of fluvial sediment. Twenty-eight core sediment samples, capturing a range of soil depths, were collected from the bed, the banks, and the floodplains of the creek and were analyzed for PAHs on a GC-MS. The results showed that PAHs concentrations were generally highest on depositional banks and were highly variable on the channel bed and in the floodplain. Further, PAH concentrations were more uniform across the cross section (bed, bank, and floodplain) at downstream sites compared to upstream. The results also showed that in erosional sites, unlike the depositional sites, there was little variation in PAHs concentration in the soil column. This analysis provides deeper insight into the transport and fate of PAHs in urban streams and floodplains, ultimately helping mitigate the impacts of pollutants on the environment.
