“…A non-parametric Mann-Kendall statistical test 15,16 reveals statistically significant declining trends at a 95% confidence level for ten POPs in weekly measured air concentrations recorded at the Zeppelin Station (1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009) (Supplementary Methods and Table S1). Similar declining trends were also reported at the Alert Station for HCHs and chlordanes 6 .…”

“…Indeed, increasing trends of some POPs, including hexachlorobenzene (HCB) and PCBs, were observed in Arctic air in the early-to mid-2000s at the Zeppelin Mountain Air Monitoring Station, Svalbard/Norway (78 • 55 N, 11 • 56 E), and at the Alert station, Canada (82 • 30 N, 62 • 20 W): potentially the result of revolatilization from the ocean owing to sea-ice retreat 6 . However, most POPs in the Arctic have shown decreasing trends since the early 1990s (refs 6,12,13).…”

“…These data contribute to the AMAP longterm measurement of POPs, intended to facilitate assessment of their transport and presence in the Arctic atmosphere and evaluation of the consequences of international control measures. 14 The results of atmospheric measurements of OCPs at Station Nord are reported here for the period 2008-2010. The aim of the study was to obtain measured concentrations of OCPs in North-East Greenland for use in assessing seasonal variations and -ultimately -long term trends, as well as to nd indications of long range transport versus reemission from the local/regional area.…”

Hexachlorobenzene (HCB), endosulfan I and hexachlorocyclohexanes (HCHs) were the predominant compounds detected in the atmosphere, followed by p,p 0 -DDE and dieldrin. Chlordane isomers and related compounds (trans-and cis-chlordanes, heptachlor and heptachlor epoxide, trans-and cis-nonachlor) were also detected. Atmospheric concentrations of the investigated compounds were correlated with temperature using the Clausius-Clapeyron equation in order to obtain information about their transport properties. The correlation between atmospheric concentrations and temperature was not significant for endosulfan I, g-HCH and p,p 0 -DDT, which indicates that direct transport from direct sources is the dominating transport mechanism for these compounds. A significant correlation with temperature was found for all the other studied pesticides and pesticide degradation products, which indicates that re-emission of these compounds from previously contaminated surfaces is an important factor for the observed variation in concentrations. Pesticide concentrations were also correlated with sea ice cover. Concentrations of the compounds that have not been in use for decades correlated with temperature and ice cover, while concentrations of compounds still in use did not correlate with either of these parameters. These observations indicate that processes such as revolatilization from the open sea surface are important mediating factors in the dynamics of anthropogenic persistent pollutants in the Arctic environment under the expected influence of climate change processes. Environmental impactThis paper reports for the rst time atmospheric concentrations of organochlorine pesticides in a high Arctic region of Greenland. These data contribute to the general knowledge about transport and dynamics of persistent pollutants in Arctic regions.

“…The processes driving the transport of POPs to the AO and their occurrence have been the subject of several studies over the last two decades [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] , including the presence of POPs in the atmosphere, seawater and to a lesser extent plankton of the AO. Chemicals such as PCBs are highly hydrophobic, as measured by the octanol-water partition coefficients (K OW ) ranging between 10 4 and 10 8 , and are semivolatile. Therefore, PCBs and other POPs can effectively undergo volatilization from primary and secondary sources, and via atmospheric transport, accumulate in aquatic organisms once deposited in the Arctic.…”

The oceanic biological pump modulates the atmospheric transport of persistent organic pollutants to the Arctic

semivolatile persistent organic pollutants have the potential to reach remote environments, such as the Arctic ocean, through atmospheric transport and deposition. Here we show that this transport of polychlorinated biphenyls to the Arctic ocean is strongly retarded by the oceanic biological pump. A simultaneous sampling of atmospheric, seawater and plankton samples was performed in July 2007 in the Greenland Current and Atlantic sector of the Arctic ocean. The atmospheric concentrations declined during atmospheric transport over the Greenland Current with estimated half-lives of 1-4 days. These short half-lives can be explained by the high airto-water net diffusive flux, which is similar in magnitude to the estimated settling fluxes in the water column. Therefore, the decrease of atmospheric concentrations is due to sequestration of atmospheric polychlorinated biphenyls by enhanced air-water diffusive fluxes driven by phytoplankton uptake and organic carbon settling fluxes (biological pump).
