“…The profiles were different from those in the Greenland Sea, where PFOA showed higher concentration than PFOS. The occurrence of PFOA and PFOS in Antarctic seal and polar skua samples strongly supported the LRT, although only trace concentration were quantified in the water samples (Giesy and Kannan, 2001;Tao et al, 2006;Schiavone et al, 2009). Local input was considered the possible source of PFASs in Antarctica.…”

“…The annual production of neutral fluorotelomer alcohols (FTOHs) was estimated as 11,000e14,000 t after 2002, and global historical production was 44,000e80,000 t for perfluoroalkyl carboxylic acids (PFCAs) (1951e2004) and 96,000 t for perfluorooctane sulfonyl fluoride (POSF) (1970e2002), respectively Dinglasan-Panlilio and Mabury, 2006;Paul et al, 2008). PFASs have been detected ubiquitously in air, water, sediment, wildlife and human beings all around the world as a result of their decades-long manufacture and applications (Schiavone et al, 2009;Bao et al, 2010;Genualdi et al, 2010;Kato et al, 2011;Li et al, 2011;Meyer 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.

“…In studies dealing with PFCAs in seabird eggs, typically longer-chain PFCAs (> 8 C-atoms) predominate, while PFOA is often not detected at all [12,36,71,[83][84][85][86][87]. This has been ascribed to a positive correlation between carbon chain length and bioaccumulation for PFC with 8 to 12 carbons [34].…”

“…Many of them are highly persistent, bioaccumulative and toxic. Furthermore, the substances themselves or their precursors are subject to long-range transport and have been detected in biota in remote areas like the Arctic and Antarctica (e.g., [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]). These findings led to the inclusion of PCBs, certain PBDEs (i.e., hexabromodiphenyl ether, heptabromodiphenyl ether, tetrabromodiphenyl ether, and pentabromo-diphenyl ether), as well as the PFCs' perfluorooctane sulfonic acid [PFOS] and its salts and perfluorooctane sulfonyl fluoride into the list of persistent organic pollutants [POPs] covered by the Stockholm Convention on POPs [17,18].…”

Levels and trends of industrial chemicals (PCBs, PFCs, PBDEs) in archived herring gull eggs from German coastal regions

Background: Polychlorinated biphenyls [PCBs], perfluorinated compounds, and polybrominated diphenyl ethers [PBDEs] were retrospectively analyzed in archived herring gull (Larus argentatus) eggs from the North and the Baltic Sea over the last 20 years. The aim was to assess temporal trends and effects of regulatory measures. Results: PCBs (sum of 7 congeners) were highest in eggs from the North Sea island Trischen, i.e., 3,710 to 20,760 ng/g lipid weight [lw] compared to 2,530 to 11,650 ng/g lw on the North Sea island Mellum and 4,840 to 9,190 ng/g lw on the Baltic Sea island Heuwiese. During the study period, PCBs decreased significantly. Concentrations of PFOS ranged between 46 and 170 ng/g wet weight [ww] at Trischen, 39 to 99 ng/g ww at Mellum, and 20 to 159 ng/g ww at Heuwiese. Since 2000 and 2003, concentration levels decreased in eggs from Mellum and Heuwiese, respectively. Perfluorooctanoic acid was the dominant perfluorinated carboxylic acid in the North Sea eggs (Trischen 2.0 to 74 ng/g ww; Mellum 2.6 to 118 ng/g ww), whereas perfluoroundecanoate [PFUnA] and perfluorodecanoate [PFDA] (means 3.9 ± 3.6 ng/g and 2.9 ± 2.3 ng/g ww, respectively) dominated in the Baltic Sea eggs. At all three locations, longerchained perfluorinated carboxylic acids (perfluorononanoate, PFDA, PFUnA, perfluorododecanoate) increased during the monitoring period. PBDE concentrations (sum of 35 congeners) in eggs were in the ranges of 282 to 2,059 ng/g lw (Mellum), 116 to 1,722 ng/g (Trischen), and 232 to 2,021 ng/g lw (Heuwiese). Congeners associated with commercial Penta-and Octa-BDE formulations decreased during the study period. No decrease was observed for technical Deca-BDE. Conclusion: Effects of regulatory measures were apparent for PCBs and Penta-and Octa-BDE, while no consistent trend is noticeable for PFOS.

a b s t r a c tNeutral Polyfluoroalkyl substances (PFASs) in the atmosphere were measured during a cruise campaign over the northern South China Sea (SCS) from September to October 2013. Four groups of PFASs, i.e., fluorotelomer alcohols (FTOHs), fluorotelomer acrylates (FTAs), fluorooctane sulfonamides (FOSAs) and fluorooctane sulfonamidoethanols (FASEs), were detected in gas samples. FTOHs was the predominant PFAS group, accounting for 95.2e99.3% of total PFASs (SPFASs), while the other PFASs accounted for a small fraction of SPFASs. The concentrations of SPFASs ranged from 18.0 to 109.9 pg m À3 with an average of 54.5 pg m À3 . The concentrations are comparable to those reported in other marine atmosphere. Higher concentrations of SPFASs were observed in the continental-influenced samples than those in other samples, pointing to the substantial contribution of anthropogenic sources. Long-range transport is suggested to be a major pathway for introducing gaseous PFASs into the atmosphere over the northern SCS. In order to further understand the fate of gaseous PFASs during transport, the atmospheric decay of neutral PFASs under the influence of reaction with OH radicals and atmospheric physical processes were estimated. Concentrations of 8:2 FTOH, 6:2 FTOH and MeFBSE from selected source region to the atmosphere over the SCS after long-range transport were predicted and compared with the observed concentrations. It suggests that the reaction with OH radicals may play an important role in the atmospheric decay of PFAS during long-range transport, especially for shorted-lived species. Moreover, the influence of atmospheric physical processes on the decay of PFAS should be further considered.
