摘要
对珠江河口生物样品中多溴联苯醚(PBDEs)的含量进行了检测。所采集的鱼类(鲬鱼,大黄鱼、银鲳、舌鳎、龙头鱼),虾类(刀额新对虾.近缘新对虾)及虾蛄类生物样品肌肉组织中10种PBDEs(BDE28,47,66,100,99,85,154,153,138,183)的含世分别为37.8~407.1ng·g^-1(脂肪归-化浓度).49.0~239.1ng·g^-1和142~444.5ng·g^-1.所有样品中,BDE47相对含量最高,其相对于∑10PBDEs的贡献为53.7%~66.9%,不同类别的鱼、虾之间PBDEs含量及组成的差别可能与不同物种之间的食性、栖息环境以及对PBDEs吸收、代谢能力的差异有关。鱼肝中PBDE含量与肌肉组织中PBDE含量的对比分析表明,多溴联苯醚在鱼肝中的富集能力高于鱼肉。
Polybrominated diphenyl ethers (PBDEs) were detected in biota samples collected from the Pearl River Estuary. The concentrations of ∑10 PBDEs(BDE28, 47, 66, 100, 99, 85, 154, 153, 138, 183) in fish species ( including Platycephalus indicus, Pseudosiaena crocea , Pampus argenteus, Cynoglossus robustus, and Harpodon nehereus ) , shrimps (including Metapenaeus ensis and Metapenaeus affinis) and Squilla oratoria were from 37.8 ng·g^-1 to 407.1 ng·g^-1 (normalized to lipid), from 49.0 ng·g^-1 to 239.1 ng·g^-1 and from 142 ng·g ^-1 to 444.5 ng·g^- 1, respectively. BDE47 was the dominant congener in all biota samples, with a contribution to ∑10 PBDEs ranging from 53.7% to 66.9%, Differences in concentrations of PBDEs and PBDE patterns in different species may be related to the different feeding habit, living environment and uptaking or elimination rate, High ratios of concentrations of PP, DEs in liver /muscle in fish species indicated thai PBDEs tended to accumulate more in liver than in muscle.
