重金属对真鲷幼鱼和黑鲷幼鱼的毒性效应

Abstract

研究了Cu、zn、Cd三种重金属对真鲷幼鱼和黑鲷幼鱼的毒性作用。结果表明Cu、zn、Cd对真鲷、黑鲷幼鱼的毒性须序均为Cu＞zn＞Cd；Cu、zn、Cd对两种幼鱼的96H半致死浓度及安全浓度：真鲷幼鱼为Cu0.31Mg/l、0.031Mg/l，zn3.6Mg/l、0.36Mg/l，Cd0.53Mg/l、0.053Mg/l；黑鲷幼鱼为Cu0.20Mg/l、0.02Mg/l，zn1.8Mg/l、0.18Mg/l，Cd0.3Mg/l、0.03Mg/l.

A study of the toxication of Cu , Zn , Cd on larval red sea bream and larval blacksea bream was conducted.The results indicated that the toxicity sequence was Cu>Cd>Zn.The 96 hMedian Lethal Concentrations and SaFe Concentrations of the two Fishes : For larval red sea bream wereCu 0.31 mg/L, 0.031 mg/L,Zn 3.6 mg/L,0.36 mg/L, Cd 0.53 mg/L,0.053 mg/L; For larvalblack sea bream were Cu 0.20 mg/L, 0.02 mg/L, Zn 1 .8 mg/L, 0.18 mg/L, Cd 0.3 mg/L , 0.03mg/L.
