slightly higher. Hexachlorocyclohexanes HCB and dieldrin concentrations, in benthic and under ice amphipod however, were not significantly different between amphipod species and only slightly higher than in zooplankton (an order of magnitude or less). Concentration increases for chlordane isomers were intermediate, with higher levels in benthic animals and concentrations between 10 and 30 times concentrations in zooplankton. Published fish muscle tissue data (Norstrom & 1985) indicates that concentrations are very similar to levels in amphipods captured under the ice. The results for a sample of liver from the Arctic eel pout Lycodes friqicus caught in the Arctic Ocean (85"N) in 1983 from the CESAR camp at a depth of 2075 m and analyzed with our data indicate that DDT, chlordane and PCBs may be concentrated in fish liver by factors of 10 - 100 over levels in muscle tissue (Table 5.3). The DDT and PCB levels in this liver sample are very similar to the levels reported for seal blubber and polar bear liver. These latter samples however, have higher concentrations of chlordane, HCH, dieldrin, and to a lesser extent, HCB. Overall concentration factors for the malor organaochlorines are summarized in Table 5.4 for air, seawater, zooplankton, pelagic and benthic amphipods, seal and polar bear tissues. Concentrations have been normalized to HCB which has arbitrarily been set to 1. The most abundaht compounds in marine mammalian tissues are present in very small amounts in air and seawater, the source of these materials to the Arctic asi in* PCBs, DDTs and chlordanes are thus magnified through the food chain to a far greater degree than more abundant compounds such as HCH and HCB.
