“…The dominance of 6-MeO-BDE 47 in the present study was also found in blubber of minke whales (Balaenoptera acutorostrata) , in male ringed seals and beluga whales (Kelly et al, 2008), in grey seals and ringed seals (Haglund et al,1997) and in pre-industrial whale oil (Teuten and Reddy, 2007). Reversed patterns were found in blubber of striped dolphins and several marine mammal species from Oceania (Melcher et al, 2005) and Brazil (Dorneles et al, submitted for publication).…”

Harbour seals (Phoca vitulina) and harbour porpoises (Phocoena phocoena) are top predators in the North Sea and consequently accumulate a variety of pollutants in their tissues. Concentrations of polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs) and their hydroxylated metabolites (HO-PCBs and HO-PBDEs) were measured in serum of wild harbour seals (n = 47) and captive harbour porpoises (n = 21). Both species exhibit long life spans and do not have extreme situations, such as complete fasting during periods of lactation, in their annual cycles. For PCBs, concentrations in adult males were slightly higher than in juveniles and lowest in juvenile females. For PBDEs, juveniles have higher levels than adult males and females, probably as a consequence of lactational transfer. However, differences between these age-gender groups were not statistical significant, indicating that individual variation was limited within each species, even without knowing the feeding status of the animals. Body condition, particularly emaciation, has a major influence on the levels of chlorinated and brominated contaminants in serum. Profiles of PCBs were CB 153 N CB 138 N CB 187 N CB 180 and CB 153 N CB 138 N CB 149 N CB 187 N CB 180 for harbour seals and porpoises respectively. For PBDEs, BDE 47 was the predominant congener followed by BDE 100 and 99 in both species. In harbour seals, concentrations of sum PCBs (median: 39,200 pg/ml) were more than 200 times higher than levels of sum PBDEs (median: 130 pg/ml) and almost 10 times higher than concentrations of sum HO-PCBs (4350 pg/ml). In harbour porpoises, concentrations of sum PCBs (median: 24,300 pg/ml) were about 20 times higher than concentrations of PBDEs (median: 1300 pg/ml). HO-PCBs were detected in only 4 harbour porpoises and this at very low concentrations. Naturally-produced MeOPBDEs were only found in harbour porpoises at concentrations ranging from 120 to 810 pg/ml. HO-PBDEs were not found in any species. In general, harbour seals accumulate less compounds and have mostly lower concentrations than harbour porpoises possibly as a result of a better developed metabolism.

“…These compounds have been reported previously in whale and fish oil (Teuten and Reddy, 2007;Covaci et al, 2007), in fish and in marine mammals (Vetter et al, 2002;Pettersson et al, 2004;Melcher et al, 2005;Losada et al, 2009;Weijs et al, 2009b). To date, no reports on their presence of algae and sponges in the Black Sea are available.…”

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.

“…The continuing presence of 1,3,6,8-tetrabromocarbazole at depths indicated by hundreds or thousands of years below the 30 cm depth at these locations would be strong evidence for natural sources playing a significant role in its presence in the environment. Persistent halogenated organic chemicals are known to accumulate in the fatty tissue of marine animals, but 1,3,6,8-tetrabromocarbazole was not detected in archived whale oil from 1921 (Teuten and Reddy, 2007), lending support to it not being a widespread contaminant in the environment prior to this time.…”
