摘要
1999年5-6月和10-11月对珠江三角洲虎门、蕉门、磨刀门3大人海河口的经济鱼类肌肉中重金属残留水平进行了调查分析,结果表明在采集的24个种类鱼样中,Zn、Ph、As 3种重金属含量分别为5.789mg/ks’0.987mg/kg、0.207mg/ks,超标率分别为45％、50％、44％。在3大人海口采集的鱼样中,肌肉内重金属含量经方差分析表明,各地点无显著差异。与80年代河口鱼类肌肉重金属含量相比,Zn、Ph、Cr含量有显著差异.
Investigation on heavy metal content in muscle of main economic fishes at three different main estuaries, i.e. Humeng, Jiaomeng and Modaomengs of River Pearl Delta during May ~ June and October ~ November 1999 has been conducted. The result showed that Zn, Pb and As contents in 24 species of fish were 5.789mg/kg, 0.987mg/ kg and 0.207mg/kg respectively, and exceeding 45%, 50% and 44% of standards respectively. After various analysis, no remarkable difference among different sampling sites, when compared with heavy metal content in 1980' s, the remarkable difference of Pb, Zn and Cr existed.
