a b s t r a c tIn this study, 54 sediment samples were collected from the Pearl River Estuary (PRE) in Southern China to study the spatial distribution and patterns of PFASs in this region. PFAS concentrations in the sediment samples ranged from nd (below detection limit) to 2.41 ng g À1 dw (dry weight) with an average value of 0.79 ng g À1 dw. PFAS concentrations were higher at the nearshore sampling sites than in the others.Perfluorobutanesulfonate (PFBS) and perfluorohexanesulfonate (PFHxS) were the two dominant compounds among the target PFASs, which may be due to their production and use as PFOS substitutes in the Pearl River Delta (PRD) areas. Significant linear relationships were found between total PFAS concentrations and total organic carbon (TOC) (R = 0.30, p < 0.05). The preliminary environmental risk assessment indicated that PFOS and PFOA in the regional sediments posed no significant ecological risk to the benthic organisms at present levels.

“…Several fluoropolymer facilities producing large amounts of PTFE and other fluoropolymers were disclosed along the river [29]. Studies by other researchers also indicated that PFOA was the predominant PFAA along the Xiaoqing River found in human blood in Zouping County [9], precipitation in Weifang City [36], mollusks in Laizhou Bay [18] and sediment in the Xiaoqing River [37,38]. However, the exact sources and fate of PFAAs, the contribution of different kinds of sources and the pollution history are still unqualified and unquantified in the Xiaoqing River Basin.…”

“…Sample extraction and analysis Sediment samples were extracted according to a previously published method with minor optimizations and modifications (Naile et al 2010;Wang et al 2013b;Zhu et al 2014). A total of 12 PFAAs, including 9 PFCAs (perfluorobutanoic acid (PFBA), perfluoropentanoic acid (PFPeA), perfluorohexanoic acid (PFHxA), perfluoroheptanoic acid (PFHpA), perfluorooctanoic acid (PFOA), perfluorononanoic a c i d ( P F N A ) , p e r f l u o r o d e c a n o i c a c i d ( P F D A ) , perfluoroundecanoic acid (PFUdA), perfluorododecanoic acid (PFDoA)), and 3 PFSAs (potassium perfluorobutanesulfonate (PFBS), sodium perfluorohexanesulfonate (PFHxS), potassium perfluorooctanesulfonate (PFOS)) were analyzed (Wang et al 2014b).…”

“…In the present study, we selected the Xiaoqing River in Shandong Province of China as an area with fluorochemical industry for the investigation, and high PFOA loads were quantified (Wang et al 2014b;Zhu et al 2014). A total of 10 samples of surface sediment along the river were collected and sequenced using Illumina high-throughput platform.…”

The characterization of bacterial community compositions and the change in perfluoroalkyl acids (PFAAs) along a natural river distribution system were explored in the present study. Illumina high-throughput sequencing was used to explore bacterial community diversity and structure in sediment polluted by PFAAs from the Xiaoqing River, the area with concentrated fluorochemical facilities in China. The concentration of PFAAs was in the range of 8.44-465.60 ng/g dry weight (dw) in sediment. Perfluorooctanoic acid (PFOA) was the dominant PFAA in all samples, which accounted for 94.2 % of total PFAAs. High-level PFOA could lead to an obvious increase in relative abundance of Proteobacteria, ε-Proteobacteria, Thiobacillus, and Sulfurimonas and the decrease in relative abundance of other bacteria. Redundancy analysis revealed that PFOA played an important role in the formation of bacterial community, and PFOA at higher concentration could reduce the diversity of bacterial community. When the concentration of PFOA was below 100 ng/g dw in sediment, no significant effect on microbial community structure was observed. Thiobacillus and Sulfurimonas were positively correlated with the concentration of PFOA, suggesting that both genera were resistant to PFOA contamination.
