摘　　要：研究了氯化镉、灭多威和硝基苯对孵化以后7d左右日本青鳉(Oryzias latipes)行为毒性。结果表明,在不同污染物中,随暴露浓度的增加,第1尾日本青鳉产生行为抑制的时间逐渐缩短,并且半数行为抑制时间(time ofhalf behavior inhibition,THBI,Y)随暴露浓度(X)呈现幂指数关系Y=aXb,其中20<a<28,-1.2<b<-0.8。实验结果表明基于日本青鳉THBI分析,能初步实现水体突发性污染事故污染水平的应急监测,从而为污染事故应急预案提供支持。Behavior inhibition of Japanese medaka（Oryzias latipes）exposed to cadmium chloride,methomyl and nitrobenzene for 7 days was investigated.The results suggested that the behavior inhibition time of the first medaka decreased with the exposure concentrations.The relationship between the time of half behavior inhibition（THBI,Y）and the concentrations（X）was Y= aXb,in which 20a28 and-1.2b-0.8.Therefore,biological emergency monitoring based on THBI could be applied in the water pollution accidents,and provide supports to emergency treatment of water pollution accidents.
