“…The lowest concentrations (20-70 ng/g) were characteristic of the littoral zone (Figure 8), whereas the highest concentrations (100-700 ng/g) were characteristic of the pelagic zone (Figure 9). The higher PAH concentrations in sediments of the pelagic zone were probably due to the higher proportion of silt and clay particles [29][30][31] in relation to sediments of the littoral zone. The results obtained in the present study are somewhat different from those published earlier [35].…”

“…It was shown that the highest PAH concentrations in the air are characteristic of urban and industrial areas of the Lake Baikal watershed. At the beginning of the 2000s, articles concerned with the PAHs in the bottom sediments of Lake Baikal and its tributaries [26][27][28][29][30][31][32] began to appear in Russian and international academic journals. The results of these studies showed that the highest concentrations of PAHs in riverine and lacustrine sediments were observed in areas located in big cities and near industrial enterprises.…”

The aim of this study was the systematization and generalization of data obtained by authors during the last decade and the comparison of these data with those obtained by other authors. Gas chromatography (GC-MS) was used for the determination of PAHs and the positive matrix factorization (PMF) model and principal component analysis (PCA) were used for source apportionment of PAHs. It was found that the total concentration of 16 priority PAHs in surface waters varied from 5 to 200 ng/L, whereas the concentration of 16 PAHs in bottom sediments varied from 50 to 700 ng/g. The 2–3-ring PAHs were dominant in water, whereas the 4–6-ring PAHs were dominant in sediments. That was due to PAHs fractionation in the soil–water system. The source apportionment results showed that the PAHs in both water and sediments mostly originated from the combustion of biomass and fossil fuels. In contrast to sediments, there was a PAH fraction in water that did not originate from a single source. The pollution of freshwater ecosystems manifested itself in the lack of correlation between values of octanol/water partitioning coefficients and sediment/water partitioning coefficients of PAHs.

“…The study emphasized the rapid transport of PAHs from the recharge area soil to the discharge area of spring water and sediments, showcasing the dynamic movement of PAHs in karst environments [177]. In another study, Nikanorov et al [178] documented the concentrations of polycyclic aromatic hydrocarbons and benzo[a]pyrene in water and sediment near the Baikal Pulp and Paper Mill, Lake Baikal, and the Selenga River delta. This research uncovered significant variations in benzo[a]pyrene levels, especially in sediments, indicating considerable pollution around the mill [178].…”

This review paper presents a comprehensive synthesis of current knowledge on the contamination of water systems by polycyclic aromatic hydrocarbons (PAHs). PAHs, organic contaminants characterized by two or more fused aromatic rings, are notably problematic due to their persistence, bioaccumulation, and significant health risks. The review commences with an examination of various sources of PAHs in aquatic environments, encompassing both anthropogenic activities, such as industrial discharges, urban runoff, and oil spills, and natural phenomena including volcanic eruptions and wildfires. Subsequently, the discussion shifts to the distribution patterns of PAHs within different aquatic ecosystems, with an analysis of factors that influence their transport. Considerable focus is placed on the entry mechanisms of PAHs into water systems and their interactions with diverse environmental matrices. Additionally, the ecotoxicological effects of PAHs on aquatic life are scrutinized, with particular emphasis on molecular, individual, and ecosystemic impacts. This includes an exploration of PAH bioaccumulation in aquatic organisms and their potential mutagenic and carcinogenic consequences. The review further addresses the challenges associated with detecting and quantifying PAHs in aquatic settings, reflecting on the advancements in analytical methodologies and the complexities introduced by their varied physicochemical properties. The paper concludes with a summary of existing regulatory frameworks and guidelines governing PAH contamination in water systems, underscoring the imperative for global collaboration in the monitoring and management of PAH pollution.

“…Early POPs studies of Lake Baikal focussed near suspected sources of pollution, detecting benzo(a)pyrene and organochlorines in bottom sediments near the Baikalsk Pulp and Paper Mill (BPPM) in the 1980s (e.g. Maatela and Paasivirta, 1990;Nikanorov et al, 2012). Higher concentrations (1-2 orders of magnitude) of PCBs and DDT have consistently been observed in the sediments, water, and biota of the southern Baikal basin, Selenga River estuary, and regions closer to industry, relative to the northern and central basins (Iwata et al, 1995;Kucklick et al, 1996;Mamontov et al, 2000).…”

Persistent organic pollutants (POPs) and polycyclic aromatic hydrocarbons (PAHs) have previously been detected in the surface sediments, water, and endemic organisms of Lake Baikal, a UNESCO World Heritage Site. The Selenga River is the primary source of freshwater to Lake Baikal, and transports pollutants accumulating in the Selenga River basin to the lake. Sources of POPs and PAHs in the Selenga River basin grew through the 20th century. In the present study, temporal changes in the concentrations of PAHs and POPs were reconstructed from two lakes in the Selenga River basin over the past 150 years using paleolimnological techniques. Increased concentrations in PAHs and PCBs were recorded initially in the 1930s. The 1940s to 1980s was the period of greatest exposure to organic contamination, and concentrations of dichlorodiphenyltrichloroethane (DDT), polychlorinated biphenyls (PCBs), hexachlorocyclohexanes (HCHs) and many PAHs peaked between the 1960s and 1980s in the two lakes. Declines in concentrations and fluxes were recorded for most PAHs and POPs in the 1980s and 1990s. Temporal trends in concentrations of total and individual compounds/congeners of PAH, PCBs, and polybrominated diphenyl ethers (PBDEs) indicate the contribution of both local and regional sources of contamination in the 20th and 21st centuries. Temporal variations in contaminants can be linked to economic and industrial growth in the former USSR after World War II and the economic decline of Russia in the late-1980s and early-1990s, as well as global trends in industrialization and development during the mid-20th century.
