Blubber of seals, harbour porpoises and fish originating from the North Sea, the Baltic Sea, as well as coastal waters of Iceland and North America were analyzed for residues of polybrominated biphenyls. According to GC/ECNI-MS, hexabromobiphenyls (hexaBBs) dominated in the samples, followed by pentabromobiphenyls (pentaBBs) and heptabromobiphenyls (heptaBBs), whereas octabromobiphenyls (octaBBs)...
Polybrominated biphenyls (PBBs) have been introduced as flame retardants in 1970. Despite decreasing application rates since the mid-1970s, PBB residues are still reported in the environment. Furthermore, environmental PBB residues often do not match the PBB pattern in technical products. To get insights into the structures of environmentally-relevant PBBs, the congener patterns of technical hexabromobiphenyl...
