研究四种浓度CA--(2+)溶液对罗非鱼嗅电图(ElECTrO-OlfACTOgrAM,简称EOg)的影响,探讨CA--(2+)对重金属中毒鱼的解毒效应,并讨论其可能机制。结果表明,1CA--(2+)对罗非鱼EOg具双重效应;2CA--(2+)能使重金属中毒鱼的EOg幅值增高,反映其具有一定的解毒作用,效果顺序为Hg--(2+)>Cu--(2+)>zn--(2+)>Cd--(2+);3CA--(2+)对Cu--(2+)+zn--(2+)混合液也具一定解毒作用。The effects of Ca2+ with four different concentrations on the electro-olfactogran (EOG) of fish (Oreochromis Sp.) are investigated by electrophysiological method.The paper discusses detoxification of Ca2+ and possible mechanism in the poisoned fish of heavy metal.The results indicate as follow:(1) Ca2+ has dual effect on the EOG of the fish.(2) The amplitude of EOG can be increased by Ca2+ in the polluted fish of single heavy metal, and the result shows Ca2+ to poisoned fish take on some detoxification, in addition, the sequence of detoxification is Hg2+>Cu2+>Zn2+>Cd2+.(3) Ca2+ also reduce certain toxicity in the poisoned fish of Cu2++Zn2+ mixture.
