Abstract
The accumulation levels of hexabromocyclododecanes (HBCDs) were measured in samples of muscletissue from crucian carp (Carassius auratus) and also in samples of associated sediments. Samples were collectedfrom 15 sites along the courses of four major rivers. Widespread contamination by HBCDs in this area wasidentified from the results of this investigation. HBCDs were found above the detection limit from all of thesampling sites. The ΣHBCDs (sum of α-, β-, and γ-HBCDs) levels ranged from 1.3 to 19 ng/g (lipid wt) inthe crucian carp musscle tissue samples, and from 0.17 to 30 ng/g (dry wt) in the associated sediment samples. The predominance of α-diastereomer in the muscle tissue of the carp and γ-diastereomer in the sediments wasidentified, accounting for 88% and 60% of the ΣHBCDs, respectively. The ΣHBCDs levels in the muscle tissuesamples of carp collected from the upstream sections of each river were much lower than those in the samplesfrom carp in the downstream sections. In addition, the ΣHBCDs levels in carp tissue samples from an isolatedsite were much lower than those in carp collected from the sites along the major rivers. This suggests thatHBCD contamination in the rivers is likely to be sourced from the environment adjacent to them.
