“…In Arctic bivalves from the Canadian and European Arctic, the OC load is predominated by PCBs, though other legacy POPs are also present (Doidge et al, 1993;Fisk et al, 2003;Rabieh et al, 2008;Tessmann, 2008). Active military sites have been identified as point sources for PCBs in bottom-dwelling organisms in the Canadian Arctic (Bright et al, 1995;Kuzyk et al, 2005). In Svalbard, town settlements such as Barentsburg have also been indicated as PCB point sources for the macro-benthos (Evenset and Christensen, 2009;Hop et al, 2001), whereas the main source of PCBs is attributed to long-range transport (Wania and Mackay, 1993).…”

a b s t r a c tOrganochlorine compounds (OC) were determined in Arctic bivalves (Mya truncata, Serripes groenlandicus, Hiatella arctica and Chlamys islandica) from Svalbard with regard to differences in geographic location, species and variations related to their size and age. Higher chlorinated polychlorinated biphenyls (PCB 101ePCB 194), chlordanes and a-hexachlorocyclohexane (a-HCH) were consistently detected in the bivalves and PCBs dominated the OC load in the organisms. OC concentrations were highest in Mya truncata and the lowest in Serripes groenlandicus. Species-specific OC levels were likely related to differences in the species' food source, as indicated by the d 13 C results, rather than size and age.Higher OC concentrations were observed in bivalves from Kongsfjorden compared to the northern sampling locations Liefdefjorden and Sjuøyane. The spatial differences might be related to different water masses influencing Kongsfjorden (Atlantic) and the northern locations (Arctic), with differing phytoplankton bloom situations.

“…5). This can be explained by the higher accumulation efficiencies of DL-PCBs compared with PCDD/Fs (Bright et al 1995;Lundebye et al 2004;Micheletti et al 2007). Congener 118 is the most abundant DL-PCB with average proportions of 65.7% of the total DL-PCB concentration in crab HP and 67.5% in crab muscle.…”

The objective of the present study was to evaluate the relationships between the quantity, toxicity, and compositional profile of dioxin/furan compounds (PCDD/Fs) and dioxin-like polychlorinated biphenyls (DL-PCBs) in estuarine sediment and in the blue crab (Callinectes sapidus). Sediment and blue crab samples were collected in three small urban estuaries that are in relatively close proximity to each other. Results show that differences between PCDD/F and DL-PCB mass concentrations and total toxic equivalents (TEQ) toxicity in sediments of the three estuaries are reflected in those of the blue crab. TEQs are higher in the hepatopancreas of the crabs than in the sediment, but the concentration factor is inversely proportional to the TEQ in the sediments. Congener profiles in the crabs are systematically different from those in the sediments, and the difference is more pronounced for PCDD/Fs than for DL-PCBs, possibly due to differences in metabolization rates. Compared with sediment profiles, more lesser-chlorinated PCDD/Fs that have higher TEFs accumulate in crab hepatopancreas. This selective bioaccumulation of PCDD/Fs results in a TEQ augmentation in crab hepatopancreas compared with sediments. The bioaccumulation in the blue crab is also selective for PCDD/Fs over DL-PCBs.

“…These compounds are found in the environment (e.g. Metcalfe 1994, Schreitmüller et al 1994, Bright et al 1995, Wania & Daly 2002, and due to their inherent chemical, physical and toxicological properties, bioaccumulation of these compounds in marine biota is of growing concern (Stebbing et al 1992, OSPAR Com 2000. These compounds are readily accumulated by organisms (Fowler et al 1978, Boese et al 1996, Koponen et al 1998, and are known to have deleterious effects on key biological processes including reproduction, development and immunity (Harding & Addison 1986, Zabel et al 1995, Chapman 1996, Krogenaes et al 1998, Coteur et al 2001.…”

The kinetic behaviour of a highly toxic PCB congener (IUPAC 77) was investigated in the sea star Asterias rubens (Linnaeus, 1758) experimentally exposed via sea water, sediments or food. Simultaneously, biological effects were assessed at the immune and subcellular levels, respectively, by measuring reactive oxygen species (ROS) production and cytochrome P450 immunopositive protein (CYP1A-IPP) expression. The results indicate that sea stars efficiently accumulate the contaminant and that most organs bioconcentrate the congener according to saturation kinetics. In contrast to what has been shown previously for the non-coplanar PCB Congener 153, biological effects induced during exposure to PCB 77 were pronounced, and affected essential functions of the sea star biology (viz. immune and cytochrome P450 systems). These findings stress the need to (1) obtain further information about similar congener-specific biological effects in this species and in other organisms in the natural environment, and (2) include, when possible, coplanar PCBs in the list of congeners to be measured in marine pollutant biomonitoring programmes.
