EDTA对鱼类EOG的影响及其在渔业养殖中使用剂量的探讨

Effect of EDTA on Fish's EOG and Exploration of Used Dosage among Fishery Breed Aquatics

观测5种浓度的EDTA对EOG的影响,研究EDTA对Cu^(2+)、Zn^(2+)、Hg^(2+)、Cd^(2+)、pb^(2+)、及cu^(2+)+Zn^(2+)中毒鱼的解毒效应,并探讨使用剂量、依据及其可能原理。结果表明:当EDTA与各种金属离子比例为1:1时,解毒效果最佳。

The effects of five concentrations of EDTA on the fish's (Oreochromis sp.) EOG are observed and detoxification of EDTA on heavy metal (Cu2+, Zn2+, Hg2+, Cd2+, Pb2+, Cu2++Zn2+) poisoned fish are studied. The paper probe into used dosage, gist and probable mechanism. The results indicated that the detoxification of the ratio is best effect when the ratio is 1:1 beteew EDTA and heavy metal ions.
