“…Some modeling and monitoring results supported the more important role of marine ocean current transport because of the larger amount of flux and the consistent variation pattern of the current direction change Armitage et al, 2006). PFOA and PFOS are representatives of the long-range transport research (Armitage et al, 2006;Yamashita et al, 2008), and in this study, they were the only two compounds detected in the Greenland Sea, AO and Southern Ocean.…”

“…Meanwhile the concentrations were all below MDL and the fresh water influence could not be confirmed. Both PFOA and PFOS can to transport through deep ocean water from NAO to the Southern Ocean (Yamashita et al, 2008;Bengtson Nash et al, 2010). PFOA was assumed to stay at the surface water so that it was more easily detected in the Greenland Sea, whereas PFOS generally go deeper in the ocean, which resulted in their occurrence in the Southern Ocean.…”

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.

“…In addition, water has become the primary reservoir of PFAAs and the major medium for their transportation due to the relatively high polarity and solubility of ionic PFAAs (Prevedouros et al, 2006;Sharma et al, 2015). Because of these physicochemical properties, PFAAs can even be used as useful chemical tracers of global circulation of ocean waters (Yamashita et al, 2008).…”

Perfluoroalkyl acids (PFAAs) can be released to water bodies during manufacturing and application of PFAA-containing products. In this study, the contamination pattern, attenuation dynamics, sources, pathways, and risk zoning of PFAAs in surface and ground water was examined within a 10 km radius from a mega-fluorochemical industrial park (FIP). Among 12 detected PFAAs, perfluorooctanoic acid (PFOA) dominated, followed by shorter-chained perfluoroalkyl carboxylic acids (PFCAs). PFAA-containing waste was discharged from the FIP, with levels reaching 1.86 mg/L in the nearby rivers flowing to the Bohai sea together with up to 273 μg/L in the local groundwater in the catchment. These levels constitute a human health risks for PFOA and other shorter-chained PFCAs within this location. The concentrations of ∑PFAAs in surface water strongly correlated with the local groundwater. The dominant pollution pathways of PFAAs included (i) discharge into surface water then to groundwater through seepage, and (ii) atmospheric deposition from the FIP, followed by infiltration to groundwater. As the distance increased from the source, PFAAs levels in groundwater showed a sharp initial decrease followed by a gentle decline. The contamination signal from the FIP site on PFAAs in groundwater existed within a radius of 4 km, and at least 3 km from the polluted Dongzhulong River. The major controlling factor in PFAA attenuation processes was likely to be dilution together with dispersion and adsorption to aquifer solids. The relative abundance of PFOA (C8) declined while those of shorter-chained PFCAs (C4-C6) increased during surface water seepage and further dispersion in groundwater.

“…Incomplete removal of PFASs by waste water treatment plants (WWTPs) (Schultz et al, 2006;Sun et al, 2011), and transport by water flow and oceanic currents (Yamashita et al, 2008) and atmosphere (Stock et al, 2007) make them ubiquitously distributed in various environmental media including air (Li et al, 2011b), water (Hansen et al, 2002;Hong et al, 2013), sediment (Higgins et al, 2005;Benskin et al, 2011), biota (Giesy and Kannan, 2001;Tao et al, 2006), and human (Hansen et al, 2001). They have even been found in some remote areas, such as the Arctic (Benskin et al, 2012) and Tibetan Plateau (Shi et al, 2010).…”
