“…Whether the concentration of PAHs in the Taihu Lake Basin exceeded the standard and whether it posed a health threat to the surrounding population had received widespread attention 16 – 18 . Since 2000, the concentration of PAHs in the sediments of the Taihu Lake Basin had ranged between 698.00 and 962.00 ng g −1 , after 209.00–3842.00 ng g −1 in 2010, and gradually changed to 4900.00–16,800.00 ng g −1 in 2021 19 – 21 , showing a continuous upward trend. It is imminent to study the concentration, source and carcinogenic risk of polycyclic aromatic hydrocarbons in the sediments of Taihu Lake in the near future.…”

To study the spatial occurrence, sources, and ecological risks of 16 PAHs, surface sediments had been collected from seven major areas of Taihu Lake, China in April 2021. Results showed that the concentrations of ∑16PAHs varied between 1381.48 and 4682.16 ng g−1, and the contents of BghiP in each sample were the highest. The PAHs concentrations in the sediments near the lakeshore were much higher than those in the central area of the lake. The sedimentary ∑16PAHs were mainly composed of molecular-weight monomers and 4-ring PAHs showed superiority (35.69–45.02%). According to the ratio of PAH monomer, the sedimentary PAHs in Taihu Lake were dominantly derived from the combustion. Through the biological toxicity assessment and the BaP equivalent (BaPE), great biological risks of PAHs monomers i.e. DahA and IcdP were found. Both concentrations of ∑16PAHs and dominant 4–6-ring monomers accompanied by carcinogenic risks in many areas of Taihu Lake increased. It is necessary to strengthen monitoring and take measures to control the input of organic pollutants.

“…As a result, PAHs have been the subject of environmental monitoring research for catchments worldwide. Numerous studies have employed water and sediment as important matrices for evaluating PAHs contamination in rivers [17][18][19], lakes [20,21], dams [22] as well as seas [23,24].…”

The Danube is one of the largest transboundary rivers word-wide, having several tributaries. The discharges from industrial activities and wastewater treatment facilities affect the river's aquatic environment. These discharges pose a serious risk to aquatic life by degrading the water and sediment quality. Therefore, 16 Polycyclic Aromatic Hydrocarbons (PAHs) compounds in six different locations were examined along the river over 12 months to investigate the temporal and special variations of the compounds in water and sediment. The findings highlighted a broad variance range in PAHs concentration in water within a year, ranging from 224.85 ng/L in summer to 365.87 ng/L in winter, whereas PAHs in sediment samples recorded values ranging from 316.72 ng/g in dry weight in summer to 422.98 ng/g in dry weight in winter. The overall results indicate that the putative anthropogenic sources of PAHs were of pyrolytic and pyrogenic origin, with pyrogenic sources being more prominent. Generally, except for Acenaphthylene and Fluorene concentrations, the eco-toxicological concerns for the aquatic environment of the Danube River do not pose a significant threat. In addition, the combined impact of the 16 PAHs pollutants in sediments suggests a low chance for negative biological impacts and low ecological risk. The total ILCR for both children and adults is more than 1/104 in all seasons, with the highest values recorded in spring followed by winter time, which becomes a matter of urgency.

“…[6]. PAHs exhibit semi-volatility, long-term persistence and bioaccumulation of persistent organic pollutants and widely occur in a variety of environmental media [7][8]. Research has indicated that the environmental behavior and bioavailability of PAHs are strongly affected by BC [9].…”

Potential risks to people's health should receive much more attention with an increasing compound pollution in urban river ecological landscape. In this paper, the concentrations of 8 heavy metals (HMs, V, Cr, Mn, Co, Ni, Zn, As and Pb), black carbon (BC, char and soot) and polycyclic aromatic hydrocarbons (PAHs) were determined in soils and river sediments collected from 72 sampling sites along the Chan-Ba River, and also were evaluated, concerning source analysis and health risks. The results indicate that the concentrations of BC and PAHs varied seasonally, and the concentration of HMs showed little seasonal variation. The concentration of BC was higher in winter than in summer, while that of PAHs was higher in summer than in winter. These pollutants were spatial heterogeneity. The concentrations of these pollutants in the middle reaches of the Ba River were much higher than those in the upper and lower reaches. These changes are attributed to the spatial-temporal distribution of local pollutant emissions and the characteristics of regional pollutant transportation and deposition. Source and cluster analysis revealed that BC, HMs and PAHs were pyrogenic (including coal and biomass combustions, vehicular emissions). The evaluation of health risk of PAHs and HMs revealed that the cancer risk for adults and children was higher than the 10 -6 and lower than 10 -4 implying low to moderate risk, and it is noted that there are higher potential risks of Phe and Flu at the middle reaches in summer and As at the lower reaches in Autumn. Therefore, pollution prevention and monitoring,
