본 연구에서는 우리나라 주요 하천에 서식하는 붕어와 주변 퇴적토에 축적된 HBCDs(hexabromocyclododecanes)의 농도를 분석하고 분포특성을 조사하였다. 조사한 15개 지점에서 구한 모든붕어 근육 및 퇴적토 시료에서 HBCDs가 검출되었는데 이는 HBCDs가 광범위하게 오염되어 있음을 나타내는 것이다. 붕어 근육과 퇴적토에 축적된 HBCDs의 총 농도(ΣHBCDs, α-, β- 및 γ-HBCD 농도를 모두 합한 값)는 각각 1.3~19 ng/g (lipid wt)과 0.17~30 ng/g (dry wt) 범위로 나타났다. 지금까지 일반적으로 알려진 다른 연구에서와 마찬가지로 붕어에서는 α-이성질체가 그리고 퇴적토에서는 γ-이성질체가 각각 88%와 60%로 가장 우세하게 축적된 것으로 나타났다. 각 하천의 하류에서 채집한 붕어 근육에 축적된 ΣHBCDs가 상류에서의 시료보다 훨씬 높은 수준으로 검출되었다. 또한 하천 하류에 위치하지만 고립된 지점에서의 붕어 근육에 축적된 ΣHBCDs는 하천의 다른 지점에서 채집한 붕어 근육에 축적된 값보다 크게 낮은 값으로 나타났다. 이는 하천의 주변 환경이 HBCDs 오염에 기여하고 있는 것을 나타내는것으로 보인다.
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.
