“…Compared to bearded seals, ringed seals had higher relative concentrations of the pentachloro substituted PCBs 101 and 99, and lower relative concentrations of the hexachloro substituted PCB 128,180,199,and 194. It has been shown that in Arctic cod, which constitutes a substantial part of the prey of ringed seals, PCB 101 constitutes a relatively high proportion of P PCB as compared to in mussels (Cleemann et al, 2000a), which is the main prey of bearded seals. On the contrary, the relative concentration of PCB 180 is higher in mussels than in the Polar cod (Cleemann et al, 2000a).…”

On the contrary, the relative concentration of PCB 180 is higher in mussels than in the Polar cod (Cleemann et al, 2000a). The dierences in the relative composition of these PCBcongeners between the two seal species are therefore probably primarily related to the composition of OCs in their prey.…”

Organochlorine burdens in blood of ringed and bearded seals from north-western Svalbard

et al. 2001

Ringed seal (Phoca hispida) and bearded seal (Erignathus barbatus) are the main prey of polar bears (Ursus maritimus), and information on organochlorines (OCs) in these pinniped species is important to understand the transport, fate and eects of persistent organic pollutants in the Arctic ecosystem. Thus, OCs were analysed in blood samples of bearded and ringed seals from the coastal ecosystem of the north-western Svalbard archipelago (Kongsfjorden, 78.55°N). The relative contribution of OCs could be ranked as follows: Ringed seal females:Bearded seal females: P PCB > P HCH P P CHL > P DDT > Mirex > HCB. Bearded seal males: P PCB > P DDT P P CHL > P HCH > Mirex P HCB. The concentrations of P PCB and P DDT were higher in ringed seals than in bearded seals, whereas P HCH was higher in bearded than in ringed seals. In ringed seal females and males P PCB was 337 95 ng/g (n 6) and 625 443 ng/g (n 6), whereas P DDT was 165 47 ng/g (n 6) and 621 559 ng/g (n 6), respectively. In bearded seal females and males, P PCB was 159 132 ng/g (n 6) and 248 93 ng/g (n 5), whereas P DDT was 46 41 ng/g (n 6) and 161 71 ng/g (n 5), respectively. The inter-species dierences are caused by a higher trophic position of ringed seals in the Svalbard ecosystem compared to bearded seals. OC levels in ringed seals at Svalbard are similar to those reported from the North-American Arctic and in the lower range compared to previously reported data from Svalbard. Ó

“…Most of these pollutants present are landfilled which is the main treatment [8] . The study showed that the content of HCB in a certain chemical soil road is greater than 100 μg/g [7] ; and the content of HCB in the soil near the outfall of a chlor-alkali plant also reaches to 29 mg • kg -1 [9] ; the content of HCB in some chemical waste is relatively high, reaching 6 000 000 μg•kg -1 [10] .…”

“…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.…”
