摘 要 ：分析了不同离子浓度的 Zn、Pb、Cu、Cd对中国鲎胚胎发育的影响。结果表明 :1 4种金属离子浓度≤渔业水域水质标准浓度 4倍时 ,对中国鲎胚胎发育无明显毒性效应 ;≥渔业水域水质标准浓度 8倍时 ,Cd离子和 Cu离子对中国鲎胚胎发育无明显影响 ,而 Zn离子组和 Pb离子组胚体发育随离子浓度提高而卵径变小 ,发育速度下降 ;2浓度为 1 .6mg/L时 ,Zn和 Pb离子组胚胎致畸率分别为 4 4%和 58% ,Pb离子组胚体孵化率仅 2 .67% ;3 4种重金属对中国鲎胚胎发育的毒性效应表现为 Pb>Zn>Cu=Cd;4中国鲎胚胎对重金属有蓄积作用 ,蓄积效应随金属种类不同而异。

Abstract:The effects of Zn、Pb、Cu and Cd on embryodevelopment of horsecrab \%T.tridentatus\% were investigated in present paper. The results showed that: (1)The embryodevelopment of this animal was not obviously affected by each of the four metals when the concentration of each ion was not more than four times of those described in Standard of Fishery Water Quality,but being disturbed in varying degrees as the concentration of each ion reached eight times or even higher than that of the Standard, for example, there i...
