Partitioning behaviour of perfluorinated alkyl contaminants between water, sediment and fish in the Orge River (nearby Paris, France)

Perfluoroalkyl acids (PFAAs) in riverine and coastal sediments of Laizhou Bay, North China

“…Distributions of ∑PFCAs without PFOA in coastal and river surface sediment in Laizhou Bay and its vicinity. than those observed in the Orge River, France (4.3±0.3 ng/g dw) (Labadie and Chevreuil, 2011), Sydney Harbour, Australia (0.80 ng/g to 6.2 ng/g dw) (Thompson et al, 2011) and the San Francisco coast, USA (nd to 3.07 ng/g dw) (Higgins et al, 2005). However, the concentrations of PFOS in this study were quite comparable with the concentrations reported in the Savannah River estuary, USA (0.3 ng/g to 0.8 ng/g dw) (Senthil et al, 2009), Roter Main River, Germany (0.07 ng/g to 0.31 ng/g dw) (Becker et al, 2008) and the Ariake Sea, Japan (0.09 ng/g to 0.14 ng/g dw) (Nakata et al, 2006).…”

“…C 9 -C 14 -PFCAs were detected in 8% to 40% of the samples, and the contributions were between 3% and 43% (mean: 13%) to ∑PFAA concentrations. PFBS and PFHxA had been widely detected in the water and sediment of urban rivers (Labadie and Chevreuil, 2011;Möller et al, 2010;Wang et al, 2011). In the rivers of Laizhou Bay, the concentrations of PFBS in sediments were near the MDL, whereas those of PFHxA were below the MDL at most sampling sites except for the heavily contaminated sites, namely, XQ1 and YKG.…”

“…Sediments had been investigated in China (Bao et al, 2010a), Japan (Ahrens et al, 2009b), the United States (Senthil et al, 2009), Germany (Becker et al, 2008), France (Labadie and Chevreuil, 2011), Spain (Gomez et al, 2011) and Australia (Thompson et al, 2011) as an important sink and reservoir of PFAAs. Previous studies had suggested levels of tens to hundreds of ng/g for PFOA and PFOS in riverine and coastal sediments (Table 1).…”

Spatiotemporal distribution and mass loadings of perfluoroalkyl substances in the Yangtze River of China

“…Sediment properties can play an important role in the distribution of organic compounds in riverine environment, but the influential processes or mechanisms are very complicated and varied from compound to compound. Perfluorocarbon chain length is the dominant structural feature influencing their partitioning onto sediment (Labadie and Chevreuil, 2011). Partitioning of PFASs onto sediment has been found strongly correlated with sediment TOC (Ahrens et al, 2009b;Higgins and Luthy, 2006).…”

Bioaccumulation and risk assessment of per- and polyfluoroalkyl substances in wild freshwater fish from rivers in the Pearl River Delta region, South China

“…Some previous studies have also reported the occurrence of PFOS in fish globally with the concentrations ranging from a few ng/g to thousands ng/g level (Senthilkumar et al, 2007;Delinsky et al, 2010;Berger et al, 2009;Quinete et al, 2009;Becker et al, 2010;Schuetze et al, 2010;Labadie and Chevreuil, 2011;Malinsky et al, 2011;Murakami et al, 2011;Zhang et al, 2011;Shi et al, 2012;Hloušková et al, 2013), and a comparison of PFOS concentrations in fish is presented in Table S7. In general, the concentrations of PFOS in fish muscle of this region ( o0.03-79 ng/g) are higher than those reported in fish from most Asian countries, such as Vietnam, Malaysia and Beijing of north China, where its concentrations ranged from 0.20 to 2.3 ng/g, and were almost at the same level with those in most European countries, such as Sweden, Czech and Germany (0.97-23 ng/g).…”
