Polybrominated diphenyl ethers in two species of marine top predators from England and Wales.

Abstract:

:During an earlier study, polybrominated diphenyl ethers were detected at high concentrations in fish and sediments downstream of a manufacturing site in NE England. We have now undertaken analysis of 14 tri- to heptabromodiphenyl ether congeners in tissues of two species of marine top predators exposed to these compounds through their consumption of fish. In this paper we report data for 47 cormorants and 60 harbour porpoises from England and Wales, sampled during the period 1996-2000. Concentrations of the summed congeners ranged from 1.8 to 140 microg kg(-1) wet weight in cormorant livers, and from not detected to 6900 microg kg(-1) wet weight in porpoise blubber. The major congeners present were generally BDE47, BDE99 and BDE100. There was little correlation between concentrations of chlorobiphenyls (as the sum of 25 individual congeners) and the sum of the 14 BDE congeners determined, particularly for the porpoises.
