“…All organochlorine compounds (OC) were found in relatively low concentrations in the four Arctic bivalve species and in the range expected for marine organisms of lower trophic levels in the Arctic (Angot, 2009;Borgå et al, 2001;Fisk et al, 2003;Hop et al, 2001;Tessmann, 2008). Their OC load was dominated by P PCB in all species with a consistent pattern of relative abundance in terms of total P OC ( P PCB > P CHLOR > a-HCH), confirming previous results for Arctic bivalves (Angot, 2009;Fisk et al, 2003;Rabieh et al, 2008;Tessmann, 2008 (COPOL project, unpubl.…”

“…The percentage of extractable organic matter (EOM) in the samples was determined gravimetrically (% EOM) in an aliquot from the original extract right after the cold-column extraction. The proportion of EOM in the analytical sample is hereafter presented as the lipid content of the samples, as has been done in other studies (Fisk et al, 2003;Hallanger et al, 2011a). Instrumental analysis was carried out on an Agilent 7890A gas chromatograph (GC) with autosampler, coupled to a 5975 C mass spectrometer (both Agilent Technologies) with helium as carrier gas.…”

“…Several studies, however, have highlighted the importance of biological factors (e.g. lipid content, habitat, feeding strategy, trophic level and seasonality) for the OC dynamics in zooplankton (Borgå et al, 2004;Hallanger et al, 2011aHallanger et al, , 2011bHargrave et al, 2000) and benthic invertebrates (Fisk et al, 2003). 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).…”

“…Few studies have focused on benthic primary consumers exclusively (Angot, 2009;Doidge et al, 1993;Fisk et al, 2003;Hop et al, 2001;Kjolholt and Hansen, 1986;Tessmann, 2008), although they do define the baseline OC levels in marine food webs. Lower trophic level organisms generally exhibit relatively low OC concentrations (Borgå et al, 2001), which are mostly influenced by the OC concentrations of sea water (dissolved fraction) and in their food (e.g.…”

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.

We investigated short‐chain (C10–13) chlorinated paraffins (SCCP) in an Arctic marine food web. In zooplankton, fishes, and ringed seals from western Hudson Bay, Canada, SCCP concentrations ranged from 38.3 to 687 ng g–1 lipid weight. Monte Carlo–simulated trophic‐adjusted biomagnification factors of individual SCCP congeners ranged from 0.07 to 0.55 for small pelagic fishes to seals. Despite relatively high concentrations in fishes, biomagnification of SCCPs within this food web appears limited. Environ Toxicol Chem 2021;40:2990–2999. © 2021 SETAC

Organochlorine contaminant concentrations, associated fugacities, and stable isotopes of nitrogen (δ(15) N) are reported for liver, whole body homogenate, and opportunistically collected samples of prey (amphipods), stomach oils, digestive tract contents, and guano for northern fulmars (Fulmarus glacialis) collected at Cape Vera, Devon Island in the Canadian High Arctic. Liver concentrations of polychlorinated biphenyls (ΣPCB) and ΣDDT were on average 49.9 ± 35.4 ng g(-1) and 29.9 ± 25.2 ng g(-1) wet weight, respectively. Whole body homogenate concentrations of ΣPCB and ΣDDT were 637 ± 293 ng g(-1) and 365 ± 212 ng g(-1) wet weight, respectively. A mass and energy balance showed that whole body contaminant concentrations, which are seldom reported for Arctic seabirds, are critical in determining contaminant exposure and associated risk to predators such as the Arctic fox (Alopex lagopus). Biomagnification in the fulmars is evident, because concentrations and fugacities of contaminants were generally one to three orders of magnitude higher than those of likely prey items. The fate of diet-derived contaminants along the digestive tract is discussed, in particular with respect to stomach oils, which are used to feed chicks and for defensive purposes. The benefits of considering both concentrations and fugacities are demonstrated and provide information on the absorption and distribution of chemicals within the fulmars and contaminant transfer to offspring and predators.
