“…The total concentration of PAHs from this study was higher than that of most rivers in Malaysia [13][14][15], Luan River estuary, China [16] and Yangtze River Estuary, China [17]. The highest total PAHs concentration in Jakarta's river was lower than that Bharalu River, India [18] and Scarpe Rivers, Northern France [19]. Fig.…”

“…PAHs have toxicity of erotogenesis, carcinogenicity, and mutagenicity, and their toxicity is even greater in aquatic environments [10][11]. PAH pollution in aquatic environments has drown worldwide attention as their effects are usually widespread and permanent [12]. Sixteen special PAHs are maintained on a priority pollutant list by the United States Environmental Protection Agency (USEPA) [13].…”

This work investigated the distribution, partitioning, and ecological risks of 16 polycyclic aromatic hydrocarbons (PAHs) in water and sediment of the Yinma River Basin in China in normal, wet, and dry seasons. Sixteen PAHs were analyzed in 17 paired sets of water and sediment samples collected from the study area. The concentrations of PAHs in water and sediment showed spatial-temporal variations, the concentrations in water ranged from 167.6 to 373.9 ng/L with a mean value of 227.9 ng/L in the normal season, from 186.0 to 386.9 ng/L with a mean value of 281.6 ng/L in the wet season, and ranged from 147.0 to 315.9 ng/L with an average value of 218.6 ng/L in the dry season, while concentrations in sediment varied from 895.6 to 2,518.2 ng/g with a mean value of 1,739.4 ng/g in the normal season, from 1,233.0 to 4,763.0 ng/g with a mean value of 2,122.6 ng/g in the wet season, and ranged from 914.2 to 5,678.5 ng/g with an average value of 1,943.7 ng/g in the dry season. Partitioning of PAHs in water and sediment was studied and the result showed that PAHs tend to absorb in sediment. Ecological risk assessments were conducted based on the species-sensitivity distribution (SSD) model, with results suggesting that ecological risks of individual PAHs in water and sediment were little, and the multiple congeners of PAHs in sediment from some sampling sites had ecological risks. Primary sources of 16 PAHs in water and sediment were identified with isomer ratios, and results indicated that primary sources of PAHs in water were identified as a mixture pattern of petroleum and combustion sources, and in sediment were identified as a mixture pattern of petroleum and grass, wood and coal combustion sources.

“…As a potent carcinogen, short-term and long-term exposure to PAHs could damage the immune, reproductive, hematopoietic and nervous systems, as well as affect overall human health [ 3 ]. Thus, PAHs have attracted worldwide attention and 16 of them were listed as priority pollutants by US EPA [ 7 , 8 ]. With the development of industry, PAHs have also been identified in drinking water resources collected from several major water systems of China, including Yellow River [ 9 ], Qiantang River [ 10 ] and Pearl River [ 11 ], where concentrations generally exceed the US EPA guideline value of 200 ng/L.…”

Polycyclic aromatic hydrocarbons (PAHs) and heavy metals exposure is related to a variety of diseases and cancer development, posing a great health risk to humans. In this study, water samples were collected from nine important water sources in Guangdong, Guangxi and Hainan provinces to determine the degree of PAHs and heavy metals contamination. Overall, the total contents of 16 PAHs and heavy metals were found within the permissible levels. In human health risk assessment, the benzo(a)pyrene equivalent concentration (BaPeq) presented a much lower level than the guideline values announced by Chinese Environmental Protection Agency (CEPA) and United States Environmental Protection Agency (US EPA), demonstrating that the PAHs contamination level in drinking water was mostly acceptable. For heavy metals, the Chronic daily intake (CDI), hazard quotient (HQ) or hazard index (HI) suggested that the water quality in nine water sources was desirable and did not present a risk to human health.
