用生物模拟采样技术模拟研究不同取代氯酚在金鱼(Crassius auratus)体内的富集和降解

摘要:
在实验室控制条件的流动体系中,研究了九种典型氯酚类化合物在半渗透膜生物模拟采样器件 (SPMD)和金鱼体内的富集动力学过程.基于氯酚污染物在SPMD中的生物浓缩和在鱼体脂肪中生物富集的差别,研究了氯酚污染物在生物体内的降解性和降解作用的结构/效应关系.结果表明氯酚类污染物在SPMD中的浓缩作用和在鱼体中的富集作用非常相似.氯酚化合物的生物降解性随氯取代基数量增加而降低,并与氯取代基的位置有关.

Abstract:
Bioaccumulation kinetics of 9 cholorophenols in semi-permeable membrane biomimetic sampling device and in fish was studied under controlled laboratory flowing-through conditions.Based on the difference between bioconcentration process in SPMD and bioaccumulation process of chlorophenols in fish the degradation and the structure/effects relationship of degradation of chlorophenols in fish was examined.The results showed that the chlorophenols under testing could be concentrated by SPMD in a similar way as it was concentrated by fish lipid.The biodegradability of chlorophenols decreased with increase of substitutions of chlorine atoms and is closely related to the position of chlorine substitution in the ring of benzene.
Key words:  Biomimetic sampling  biodeg radation  cholorophenols  Golden fish
