| Abstract | Hexabromocyclododecane (HBCDD) belongs to the c lass of cycloaliphatic brominated name retardants (BFRs) and is used primarily in the building industry as a thermal insulator additive in polystyrene foam. Secondary uses arc in upholstery textiles. HBCDD is synthesized industrially by the addition of bromine to cis-trans-trans-1,5,9-cyclododecatriene. The resulting technical mixture contains three diastereoisomers (a, p. y. Figure 1) existing in proportions of approximately 6. 8 and 80%, respectively. together with other lower brominated impurities. In 2001, the global market demand for HBCDD was 16700 tonnes. The demand for HBCDD is now second to the deca-BDEs. The physical chemical properties of HBCDD are similar to those of PBDEs and other persistent organic pollutants, including polychlorinated biphenyls (PCBs), which are known to be persistent, bioaccumulative and toxic. This study examine the biomagnification of a and y- HBCDD congeners in a Lake Ontario food web. Samples were analyzed by liquid chromatography tandem mass spectrometry (LC/MS/M). |
