摘要
采用暴露实验方法,研究了不同浓度的Cu(Cu2+)对栉孔扇贝(Chlamys farreri)鳃、肌肉、内脏团组织中Cu蓄积量及过氧化氢酶(CAT)活性的影响.结果表明:随水体中Cu浓度的升高,扇贝各组织中Cu蓄积量明显上升,Cu蓄积量顺序为:内脏>鳃>肌肉.Cu浓度对栉孔扇贝各组织中过氧化氢酶(CAT)活性均有明显影响,各组织中酶活性均随Cu浓度升高表现为抑制—诱导—抑制的规律.这表明,栉孔扇贝各组织中CAT酶对水体中Cu污染反映敏感,存在计量-效应关系,对海洋Cu早期污染具有指示作用.
An exposure experiment was made to study the effect of copper （Cu） at different concentrations on its accumulation and CAT activities in gills, muscle and visceral mass of Chlamysfarreri. The results showed that Cu accumulation in the tissues increased significantly with the increase of Cu concentration in seawater, and the accumulation was in a descendant order： visceral mass 〉 gill 〉 muscle. Cu concentration could obviously affect CAT activities and the restraint - inducement - restraint law could be seen with the increase of Cu concentration. The results also showed that the CAT in the tissues of C. farreri was sensitive to Cu contamination in seawater, which indicated early Cu pollution in sea. Fig 2, Tab 1, Ref 19
