“…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.…”

“…CB 180 is present in a higher proportion in Aroclor 1260 whereas CBs 101, 118 and 138 are indicative for Aroclor 1254 (Thompson et al, 1996). Although CB 153 is the predominant congener in this study and in other studies conducted in the North Sea (Covaci et al, 2002;Weijs et al, 2009a) and the ratios of CB 180 and CB 138 to CB 153 are similar in both areas, the higher ratio of CB 101 and CB 118 to CB 153 in the Black Sea might be indicative for a higher use of PCB mixture Aroclor 1254 in the Black Sea area compared to the North Sea.…”

“…Higher contributions of the p,p 0 -DDX metabolites were previously also found by Montie et al (2009) in cerebellum grey matter and cerebrospinal fluid of Atlantic white-sided dolphins, by Covaci et al (2002) in liver of harbour porpoises, and by Hoekstra et al (2003) in blubber of bowhead whales, beluga whales, ringed seals and bearded seals. Increasing concentrations of p,p 0 -DDE and decreasing concentrations of p,p 0 -DDT can be explained by a higher metabolism of DDT in marine mammals relative to their prey together with the bioaccumulation of DDT metabolites, as suggested by Hoekstra et al (2003).…”

“…Levels of PCBs and PBDEs in blubber and liver were lower than concentrations reported for harbour porpoises from the North Sea (Covaci et al, 2002;Weijs et al, 2009a) and were also lower than levels of PCBs measured in blubber of adult males from the Black Sea in 1993 (Tanabe et al, 1997a). This is the first study to report on PBDEs in harbour porpoises from the Black Sea, therefore, there are no results of PBDEs in Black Sea marine mammals to compare with.…”

“…To enable comparisons with previous reports, the ratio of each of the seven PCBs (IUPAC numbers 28, 52, 101, 118, 138, 153 and 180), proposed by the International Council for the Exploration of the Sea (ICES) to CB 153 was calculated for the liver and blubber of harbour porpoises from the Black Sea and the North Sea (data of liver and blubber from Covaci et al (2002) and Weijs et al (2009a), respectively; Fig. 2).…”

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.

PBDEs are persistent organic pollutants, and have the capability to produce adverse effects on organisms. Aquatic piscivorous species at higher trophic levels have the greatest exposure risk. Information on the toxic potency of a commercial PBDE mixture, DE-71, to mink and American kestrel was reviewed, and dietary- and tissue-based TRVs were derived and evaluated for ecological risk assessment of aquatic piscivorous species inhabiting wetland areas in China. The effect on mink thyroid function was identified as the most appropriate and protective endpoint for deriving the TRV s for mammals. The TRV was based on dietary exposure, and wa s0.1 mg DE-71/kg (wm) or 0.01 mg DE-71/kg (bm)/day (ADI); for liver of mammals,the TRV was 1.2 mg LPBDEslkg (lm). For birds, reproductive effects on American kestrels were used to derive the TRVs, in which an overall UF of 3.0 was used. The TRV was based on dietary exposure, and was 0.1 mg DE-71/kg (wm) or 0.018 mg DE-71/kg (bm)/day (ADI); for eggs of birds, the TRV was 2.35 jlgLPBDEs/g (lm). Reported concentrations of PBDEs in livers of aquatic mammals found dead, and in fish and bird eggs from Chinese wetland areas were compiled and compared to the corresponding criteria values. Results indicated that TRV values reported in this study can be used as indicators for screening-level risk assessment of piscivorous species in Chinese aquatic systems. Furthermore, based on monitoring concentrations of PBDEs in fishes from two lakes (DCL and TL) in China and the dietary-based TRV of 0.1 mg DE-71/kg (wm), a screening-level risk assessment of PBDEs was performed for predatory birds and mammals. The results suggest that concentrations of PBDEs in these two areas would not be expected to cause any adverse effects on the local fish-eating wild birds and mammals.
