铜和锌离子对真鲷幼鱼组织酶活性的影响 %A 戴家银 %A 郑微云 %A 王淑红 %J 环境科学 %D 1998 %I %X This paper reported the effects of Cu2+ and Zn2+ on activities of catalase (CAT),glutamic pyruvic transaminase (GPT) and pepsin in the tissues of red sea bream P.major.Red sea breams were exposed to different concentrations of cupric sulfate solution (0.5,0.75,1.5mg/L)and zinc sulfate solution (1,2,4mg/L)for 4 days.The results showed that the CAT activities in gill and liver and pepsin activities were inhibited by Cu2+ and Zn2+.At the highest Cu2+ concentration groups,the CAT activities in gill and in liver and pepsin activities decreased 73%,33% and 42.8% in relation to control,respectively,while at the highest Zn2+ concentration groups,the CAT,GPT and pepsin activities decreased 30%,68.5% and 32.8% in relation to control,respectively.The GPT activities of liver in P.major decreased at all exposure groups.The GPT activities of liver decreased 76% and 67% in relation to control at highest Cu2+ and Zn2+ concentration groups,respectively.The effects of Cu2+ and Zn2+ on the CAT,GPT and pepsin had concentration response relationship. %K copper %K zinc %K Pagrosomus major %K CAT %K GPT %K pepsin
