TEMPORAL TRENDS OF POLYBROMINATED DIPHENYL ETHERS AND HEXABROMOCYCLODODECANE IN SWEDISH PEREGRINE FALCON (FALCO PEREGRINUS) EGGS
A temporal trend study of brominated flame retardants in eggs from peregrine falcon (Falco peregrinus), a terrestrial bird of prey, is presented. Eggs collected between 1974 and 2007 were analyzed for the major constituents of the Penta-, Octa- and Decabromodiphenyl ether technical products (BDE-47, -99, -100, -153, - 183 and -209), and hexabromocyclododecane (HBCD). Concentrations of BDE-99, -100, -153, -183, -209 and HBCD increased during the first twenty years of this study. After the early 2000s, BDE- 99, -100, -153 and -183 concentrations decreased, whereas BDE-209 and HBCD concentrations continued to increase. There is a change in BDE congener patterns over time, with a shift from the dominance of BDE-99 and -47 until late 1980s, to BDE-153 being the predominant congener later on. The Swedish peregrine falcons migrate to southwest Europe during winter and their body burdens of BFRs reflect the general exposure situation in Europe.
