Perfluorinated compounds in the Pearl River and Yangtze River of China

Sediment–water distribution of perfluorooctane sulfonate (PFOS) in Yangtze River Estuary

“…Except the high value at location BZ, the PFOS levels detected for other sampling locations were comparable with values reported in Great Lakes (21-70 ng L À1 ) (Boulanger et al, 2004) and in sixteen Japanese rivers (0.2-157 ng L À1 ) (Saito et al, 2003). The PFOS values investigated in this study were much greater than that detected in Huangpu River (0.62-14 ng g À1 ) (So et al, 2007).…”

“…Reports on the pollution profiles of Yangtze River Estuary revealed that the estuary was the major depositor of many pollutants (Liu et al, 2003;Shen et al, 2006). Studies showed that the concentration of PFOS are in the range of 0.62-14 ng L À1 in Yangtze River (So et al, 2007), the concentration was 52.6 ng L À1 in the surface seawater from Shanghai (Wei et al, 2007a) and even 7.6 ng L À1 in the tap water in Shanghai (Mak et al, 2009). Consequently, to study the salinity dependent PFOS distribution in the Yangtze River Estuary may reveal important mechanism in understanding the fate and transport pathways of PFOS during the landocean interaction.…”

Perfluoroalkyl and polyfluoroalkyl substances in the lower atmosphere and surface waters of the Chinese Bohai Sea, Yellow Sea, and Yangtze River estuary

“…In contrast, the PFOS concentrations in the South China Sea were higher than those of the presently studied seas. Additionally, the PFOS concentrations were higher than the PFOA concentrations in the South China Sea, and the same compositional pattern was observed in the surface river waters from the Pearl River or the Pearl River estuary Pan et al, 2014;So et al, 2007;Zhang et al, 2013). However, an inverse pattern was observed in the Bohai Sea, Yellow Sea, and Yangtze River estuary, as well as most other rivers studied in China P.…”

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

“…But in recent three decades, this river has been suffered more from industrial pollution, agricultural run-off and siltation. However, little information at the catchment scale is available about PFASs contamination in the Yangtze River in the literature (So et al, 2007;Jin et al, 2009;Lu et al, 2011).…”
