五氯苯酚(PCP)在鱼体胆囊内积累的研究

STUDIES ON THE ACCUMULATION OF PENTACHLOROPHENOL (PCP) IN GALL BLADDER OF FISH

  • 摘要: 鱼体吸收水中的异生物质能迅速、大量地分配主胆囊。胆囊的功能好像一个强烈的生物浓集器,杂交鲫暴露在含PCP水溶液中48h,胆囊对五氯苯酚(PCP)的富集系数(BCF)高达11365.胆囊积累和排除PCP是随水温升高而增快的。草鱼胆汁内积累的PCP90%以上为结合态,并随暴露时间延长而增加,48h残留达到904mg/kg;BCF为6027.草鱼暴露在自来水和东湖水中48h,用气相色谱分析胆汁内的有机物分别为24和25个。这一结果说明了鱼胆汁可能用于监测水中某些异生物质。

     

    Abstract: The xenobiotics in water absorbted by fish can be rapidly transported to the gall bladder.The bioconcentration factor(BCF)of PCP in gall bladder of hybrid crucian carp was 11365after 48h exposure.The accumulation and excretion of PCP in gall bladder were increasedwith the rise of water temperature.More than 90% of the whole PCP were conjugated-PCP in the bile of the grass carp.The binary concentration of the conjugated-PCP increased withthe exposure duration and reached a level of 904 mg/kg and a BCF of 6027 at 48h. The bileof grass carp exposed in both tap water and Donghu lake water for 48h was founded 24 and25 compounds(chromatogram)respectively as measured by GC.The results suggest that it issuitable to monitor xenobiotics in water.
