“…[69,71,77,78,87,88] This specific odd-even PFCA pattern supports the hypothesis of atmospheric fluorotelomer alcohol (FTOH) degradation as a source of PFCAs. For example, 8 : 2 FTOH degrades to equal amounts of PFOA and PFNA, but PFNA has been shown to be more bioaccumulative than PFOA, resulting in higher PFNA levels in organs of biota compared to PFOA.…”

Environmental context. Polyfluoroalkyl compounds are used in a variety of industrial and consumer applications, including polymer production and for surface treatment of textiles and paper. Research over the last 10 years has shown that these compounds are ubiquitous environmental contaminants -they are extremely persistent, show toxic effects and accumulate in the food chain. We evaluate global, temporal and spatial trends of these important emerging contaminants.Abstract. This review gives an overview of existing knowledge of polyfluoroalkyl compounds (PFCs) in humans and in marine biota. Temporal trends and spatial distribution of PFCs were globally compared in humans, marine mammals, seabirds and fish. In general, PFC concentrations in the environment have increased significantly from the beginning of the production up to the 1990s. After the phase-out of perfluorooctane sulfonyl fluoride (POSF) production starting in 2000, PFC concentrations in humans generally decreased. In marine biota no clear temporal trends were observed. The temporal trends depended on the species, their trophic levels and the geographical locations. PFC patterns in humans and in marine wildlife species were compared regarding perfluorooctane sulfonate (PFOS), perfluorooctanoate (PFOA), their shorter and longer chain homologues (C 4 -C 15 ) and precursor compounds. Finally knowledge gaps were identified and recommendations for future work were presented.

“…Some previous studies have also reported the occurrence of PFASs, especially PFOA and PFOS in river water globally (Hansen et al, 2002;Mclachlan et al, 2007;Murakami et al, 2008;Yeung et al, 2009;Nakayama et al, 2010;Hong et al, 2013;Wang et al, 2013;Zhang et al, 2013). In general, the PFAS concentrations in the Yangtze River were lower than those in other rivers in the world.…”

“…Although the PFAS concentrations in the Yangtze River (maximum concentration for PFOA and PFOS were 18 ng/L and 3.93 ng/L, respectively) are much lower than those in the majority rivers in the world (e.g. the PFOA and PFOS concentrations in Tamagawa were 107 ng/L and 143 ng/L; tens to hundreds of ng/L for individual PFAS in Mississippi river) (Yeung et al, 2009;Nakayama et al, 2010), the mass loading of PFASs in the Yangtze River are still higher than those in other rivers due to its huge annual water flow (annual mass loading of PFOA and PFOA in Tamagawa were 0.045 tons and 0.060 tons) (Yeung et al, 2009). But the mass loading of PFASs was slightly lower than the European rivers, with the annual mass loading of PFHxA, PFHpA, PFOA and PFNA being 2.8 tons, 0.86 tons, 14.3 tons and 0.26 tons (McLachlan et al, 2007), and much lower than that in the Mississippi River with higher PFAS concentrations (Nakayama et al, 2010).…”

“…PFCAs and PFSAs have been detected in global oceans as well as in some remote lakes (Yamashita et al, 2005;Ahrens, 2011). Global transport by marine ocean currents was indicated as the major pathway of PFASs delivery to non-emission regions by both monitoring and modeling results (Yeung et al, 2009;Stemmler and Lammel, 2010). Significant relationship had been reported between PFASs concentration and mortal disease in marine organisms, and world wide detection of PFASs in serum has been of utmost concern Bonefeld-Jorgensen et al, 2011;Shankar et al, 2011).…”

a b s t r a c tThe global distribution and long-range transport of polyfluoroalkyl substances (PFASs) were investigated using seawater samples collected from the Greenland Sea, East Atlantic Ocean and the Southern Ocean in 2009e2010. Elevated levels of SPFASs were detected in the North Atlantic Ocean with the concentrations ranging from 130 to 650 pg/L. In the Greenland Sea, the SPFASs concentrations ranged from 45 to 280 pg/L, and five most frequently detected compounds were perfluorooctanoic acid (PFOA), perfluorohexanesulfonate (PFHxS), perfluorohexanoic acid (PFHxA), perfluorooctane sulfonate (PFOS) and perfluorobutane sulfonate (PFBS). PFOA (15 pg/L) and PFOS (25e45 pg/L) were occasionally found in the Southern Ocean. In the Atlantic Ocean, the SPFASs concentration decreased from 2007 to 2010. The elevated PFOA level that resulted from melting snow and ice in Greenland Sea implies that the Arctic may have been driven by climate change and turned to be a source of PFASs for the marine ecosystem.
