Archived specimens of the scavenging amphipod Eurythenes gryllus, collected from 2075-4250 m below the surface on five expeditions to the western and central Arctic Ocean between 1983-1998, were analyzed for total mercury (sum-Hg), methyl mercury (MeHg), polychlorinated biphenyls (PCBs) and other industrial or byproduct organochlorines (chlorobenzenes, pentachloroanisole, octachlorostyrene), organochlorine pesticides (OCPs), and polybrominated diphenyl ethers (PBDEs). Median sum-Hg concentrations ranged from 70 to 366 ng g-1 wet weight (ww). MeHg concentrations (3.55 to 23.5 ng g-1 ww) accounted for 1.7 to 20.1% (median 3.7%) of sum-Hg. Sum-Hg and MeHg were positively and significantly correlated with ww (sum-Hg r2 = 0.18, p = 0.0004, n=63; MeHg r2 = 0.42, p = 0.0004, n=25), but not significantly with δ13C nor δ15N. Median concentrations of total persistent organic pollutants (POPs) ranged from 9750-156000 ng g-1 lipid weight, with order of abundance: sum-TOX (chlorobornanes quantified as technical toxaphene) > sum-PCBs > sum-DDTs > sum-chlordanes > sum-mirex compounds > sum-PBDEs ~ sum-chlorobenzenes ~ octachlorostyrene > alpha-hexachlorocyclohexane ~ hexachlorobenzene ~ pentachloroanisole. Enantioselective accumulation was found for the chiral OCPs o,p'-DDT, cis- and trans-chlordane, nonachlor MC6 and oxychlordane. Lipid-normalized POPs concentrations were elevated in amphipods with lipid percentages ≤10%, suggesting that utilization of lipids resulted in concentration of POPs in the remaining lipid pool. Multidimensional Scaling (MDS) analysis using log-transformed physiological variables and lipid-normalized organochlorine concentrations distinguished amphipods from the central vs. western arctic stations. This distinction was also seen for PCB homologs, while profiles of other compound classes were more related to specific stations rather than central-west differences.
