“…1 Numerous studies on the global distribution of persistent organic pollutants [2][3][4][5][6][7][8] support the mechanistic understanding developed by Wania and Mackay 9,10 of the movement of relatively volatile chemicals throughout the global environment along with cold trapping of more volatile compounds at high latitudes. However, more recently, several studies have pointed out the potential importance of aerosol-mediated LRAT for compounds such as brominated diphenyl ethers (BDEs), in particular, decabromodiphenyl ether (BDE209).…”

Brominated diphenyl ethers were measured in air, snow and sea ice throughout western Antarctica between 2001 and 2007. BDEs in Antarctic air were predominantly associated with aerosols and were low compared to remote regions of the northern hemisphere, except in Marguerite Bay following the fire at Rothera research station in Sept. 2001, indicating that this event was a local source of BDE209 to the Antarctic environment. Aerosol BDE47/100 reflects a mixture of commercial pentaBDE products; however, BDE99/100 is suggestive of photodegradation of BDE99 during long range atmospheric transport (LRAT) in the austral summer. BDEs in snow were lower than predicted based on snow scavenging of aerosols indicating that atmospheric deposition events may be episodic. BDE47, -99, and -100 significantly declined in Antarctic sea ice between 2001 and 2007; however, BDE209 did not decline in Antarctic sea ice over the same time period. Significant losses of BDE99 and -100 from sea ice were recorded over a 19 day period in spring 2001 demonstrating that seasonal ice processes result in the preferential loss of some BDEs. BDE47/100 and BDE99/100 in sea ice samples reflect commercial pentaBDE products, suggesting that photodegradation of BDE99 is minimal during LRAT in the austral winter.

“…Although the application of organochlorine pesticides has been banned in developed countries, they are still ubiquitous in marine, freshwater, and estuarine food chains (Maruyama et al, 2000;Tanabe et al, 1994;Iwata et al, 1994;Bard, 1999;Glynn et al, 1995), and have been associated with abnormal development of the reproductive system of wild animals (Simonich and Hites, 1995;Connell et al, 2003;Weber and Goerke, 1996). Another category of compounds of global concern is dioxins including co-PCB.…”

Concentrations of hexachlorocyclohexanes (HCHs), hexachlorobenzene (HCB), pentachlorobenzene (penta-CB), polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), coplanar polychlorinated biphenyls (coPCBs), 1,1,1-trichloro-2,2-bis( p-chlorophenyl)ethane (DDTs, including p,pV -DDT; o,pV -DDT; p,pV -DDD; o,pV -DDD; p,pV -DDE; o,pV -DDE; p,pV -DDMU), nonylphenol (NP), and nonylphenol polyethoxylates (NPEOs) were measured in sedimentary cores from Bohai Bay (one core) and its adjacent river, the Nanpaiwu River (two cores), North China. While a-, h-, and g-HCHs were detected in similar abundance in the two cores from the Nanpaiwu River, only a-HCH was detected in the Bohai Bay core, suggesting that a-HCH might be more resistant to degradation than h-or g-HCHs. The concentrations of HCHs and HCB in the core from Bohai Bay were in the range of 0.8-140 and 9.1-1300 ng/g dry wt, respectively, whereas in the cores from the Nanpaiwu River, the maximum concentrations of HCHs and HCB reached 84,200 and 141,400 ng/g dry wt, respectively. There was a similarity of sedimentary profiles between HCHs and HCB in the three cores. The concentration of PCDDs/DFs in Bohai Bay was 0.5-3.5 ng/g dry wt [1.6-6.4 toxic equivalents (TEQ) world health organization (WHO) pg/g], far lower than the concentrations in the core samples taken from the Nanpaiwu River (the maximum concentration: 9200 ng/g dry wt; 22,000 TEQ WHO pg/g). The congener profiles of PCDD/DFs and co-PCB in the cores were similar to those in PCP, and the concentration of co-PCBs was related to that of PCDDs/DFs. In addition, the concentrations of HCH, HCB, PCDD/Fs, and co-PCB all decreased linearly relative to total organic carbon content (TOC) in surface sediment from the river to Bohai Bay. The concentration of DDTs ranged from 1.6 to 12.3 ng/g dry wt in Bohai Bay, significantly different from the profiles from the Napaiwu River (29.3 ng/g dry wt). An abundance of the compounds o,pV -DDE and o,pV -DDD were detected in the cores. The sedimentary profiles of NP and NPEOs were similar, and two peak concentrations of NP/NPEOs were found at the subsurface and subbottom in the core from Bohai Bay, respectively. The concentration of NP and NPEOs in the cores from the Nanpaiwu

“…Because microbial communities are at low trophic level in aquatic systems, and because they constitute an important biomass available for the higher predators, HCB-polluted microbial communities can transfer these contaminants to higher trophic level animals through the food chains. Studies have been focused on bioaccumulation of HCB in higher trophic levels, such as krill, mussels, oysters, amphipods, fish and cormorant (Ernst, 1986;Falandysz et al, 1994;Weber and Goerke, 1996;Looser et al, 2000;Corsolini et al, 2001;Cleeman et al, 2002;Pa ez-Osuna et al, 2002;Blais et al, 2003;Monirith et al, 2003;Voorspoels et al, 2004;Barber et al, 2005). Compared to the microbial communities, higher concentration ratios of HCB were observed in higher trophic levels.…”

“…HCB is practically insoluble in water, but is highly lipid-soluble and bioaccumulative (Courtney, 1979;ATSDR, 2002). Studies have focused on bioaccumulation of HCB in higher trophic levels, such as fish, krill, mussels, oysters, and amphipods (Ernst, 1986;Falandysz et al, 1994;Weber and Goerke, 1996;Looser et al, 2000;Corsolini et al, 2001;Cleeman et al, 2002;Pa ez-Osuna et al, Project supported by the Key Project of Chinese Ministry of Education (No. 104250).…”
