“…This is a typical and well known finding, not only in several marine mammal species (e.g. Covaci et al, 2002;JohnsonRestrepo et al, 2005;Ikonomou and Addison, 2008;Shaw et al, 2008Shaw et al, , 2009Montie et al, 2009;Weijs et al, 2009a), but in various fish species (Voorspoels et al, 2003(Voorspoels et al, , 2004Johnson-Restrepo et al, 2005;Shaw et al, 2009) as well. CB 153 was followed by CB 138 and CB 149, which is different from PCB profiles in pinnipeds (Weijs et al, 2009a), but similar to the profile in harbour porpoises from the North Sea (Weijs et al, 2009a) and again very specific for harbour porpoises.…”

a b s t r a c tHarbour porpoises are one of the three cetacean species inhabiting the Black Sea. This is the first study to report on polybrominated diphenyl ethers (PBDEs) and naturally-produced compounds, methoxylated PBDEs (MeO-PBDEs) and polybrominated hexahydroxanthene derivatives (PBHDs), in tissues (kidney, brain, blubber, liver, muscle) of male harbour porpoises (11 adults, 9 juveniles) from the Black Sea. Lipid-normalized concentrations decreased from muscle > blubber > liver > kidney > brain for the sum of polychlorinated biphenyls (PCBs) and for the sum of PBDEs. Among the naturally-produced compounds, levels of PBHDs were higher than of MeO-PBDEs, with tri-BHD and 6-MeO-BDE 47 being the dominant compounds for both groups, respectively. Concentrations of naturally-produced compounds decreased from blubber to brain, similarly to the sum of DDT and metabolites (DDXs). Concentrations of DDXs were highest, followed by PCBs, HCB, PBHDs, PBDEs and MeO-PBDEs. Levels of PCBs and PBDEs in blubber were lower than concentrations reported for harbour porpoises from the North Sea, while concentrations of DDXs were higher.

“…To test whether the calculated fish levels of PCB 99, 101 and 149 were comparable with real concentrations in fish, the patterns of PCBs reported in fish were taken into account as well. In the North Sea, levels of PCB 149 in several fish species may reach relatively high concentrations which are between 30 and 50% of the levels of PCB 153 (Voorspoels et al, 2004). The concentration used in the present study for PCB 149, which is 0.7 ng/g ww or 64% of 1.1 ng/g ww (input used in the PCB 153 model (Weijs et al, 2010b), seems therefore already high enough.…”

“…Consequently, an increase in elimination half-life in the PCB 149 model was assumed to be more logic than an increase in dietary input of fish. Similar, in fish species from the North Sea, PCB 99 is between 24 and 35% of the concentration of PCB 153 (Voorspoels et al, 2004). This would give a concentration of PCB 99 between 0.26 and 0.39 ng/g ww.…”

In the last decade, physiologically based pharmacokinetic (PBPK) models have increasingly been developed to explain the kinetics of environmental pollutants in wildlife. For marine mammals specifically, these models provide a new, non-destructive tool that enables the integration of biomonitoring activities and in vitro studies. The goals of the present study were firstly to develop PBPK models for several environmental relevant PCB congeners in harbor porpoises (Phocoena phocoena), a species that is sensitive to pollution because of its limited metabolic capacity for pollutant transformation. These models were tested using tissue data of porpoises from the Black Sea. Secondly, the predictive power of the models was investigated for time trends in the PCB concentrations in North Sea harbor porpoises between 1990 and 2008. Thirdly, attempts were made to assess metabolic capacities of harbor porpoises for the investigated PCBs. In general, results show that parameter values from other species (rodents, humans) are not always suitable in marine mammal models, most probably due to differences in physiology and exposure. The PCB 149 levels decrease the fastest in male harbor porpoises from the North Sea in a time period of 18 years, whereas the PCB 101 levels decrease the slowest. According to the models, metabolic breakdown of PCB 118 is probably of lesser importance compared to other elimination pathways. For PCB 101 and 149 however, the presence of their metabolites can be attributed to bioaccumulation of metabolites from the prey and to metabolic breakdown of the parent compounds in the harbor porpoises.

“…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.…”
