“…It can be seen that the distribution of the TEQ has significant spatial differences (Figure 5). This is similar to the situation in Sanliqi Lake; except for some points where the TEQ concentration is higher, all other points are less than 2.8 ng/L, which is lower than the limit value of the China Surface Water Environmental Quality Standard [23]. The first and second highest TEQ values of 5.31 and 4.93 ng TEQ/L were detected at sites D5 and T7, respectively.…”

“…More specifically, the concentrations of the ∑16PAHs in Dong Lake and Tangxun Lake were 13.05-989.09 ng/L and 12.92-442.53 ng/L, with AM values reaching up to 155.21 ng/L and 80.39 ng/L, respectively. Globally, the ∑ 16 PAH values from Dong Lake and Tangxun Lake were much higher than those reported in the Seine River, Tiber River, New York Estuary, and the Wuhan section of the Yangtze [18][19][20][21]; slightly higher than the results recorded in the Yellow River Delta and Poyang Lake [3,22]; similar to those in Sanliqi Lake and Yinjia Lake [23]; and tens to hundreds of times less than those in the Daliao River Estuary and Minjiang River [4,24].…”

Polycyclic aromatic hydrocarbons (PAHs) are a group of highly toxic organic pollutants. At present, there has only been limited research into PAH contamination in Tangxun Lake and Dong Lake, which are the first and second largest urban inland lakes in China, respectively. This study investigated the concentration, spatial distribution, sources, and ecological risks of PAHs in the water from Dong Lake and Tangxun Lake. The focus of this study is to use models to analyze the sources of PAHs, as well as their potential toxicity to humans, in the water bodies of Dong Lake and Tangxun Lake. This study performed liquid–liquid extraction to extract PAHs from lake water samples using dichloromethane and then used gas chromatography–mass spectrometry (GC-MS) to quantitatively analyze the PAHs in the samples. The total concentration of the ∑16PAHs showed high variability among different sampling points, ranging from 12.92 to 989.09 ng/L, with an arithmetic mean of 121.97 ng/L. The composition of the ∑16PAHs was mainly concentrated at a low molecular weight (>70%). The molecular distributions of PAH studies, combined with positive matrix factorization (PMF), indicate that oil and coal combustion are the main sources of PAHs in Dong Lake and Tangxun Lake. The model of PMF succeeded in identifying and quantifying five sources with similar contributions: the combustion of petroleum products, heavy oil burning, coal combustion, traffic emissions, and natural gas and oil combustion mixed. According to toxicity equivalency (TEQ) and lifelong cancer risk (ILCR) research, PAHs from traffic sources in the environment may be more toxic, and the potential carcinogenic risk of PAH pollution to humans in Tangxun Lake and Dong Lake water bodies is relatively inferior.

“…Since the attempt to identify PAH sources by comparing the PAH profiles of water and source emissions failed, it was decided to identify them using the diagnostic ratio (DR) approach [65]. Four PAH isomer concentration ratios such as ANT/(ANT + PHE), FLT/(FLT + PYR), BaA/(BaA + CHR) and IcdP/(IcdP + BghiP) were used as source tracers [1,66,67].…”

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.
