| 摘 要： | 采用等毒性单位比的方法研究了对氯硝基苯(para-nitrochlorobenzene,P-NCB)、间二硝基苯(m-dinitrobenzene,M-DNB)、2,4-二硝基苯氯苯(chloro-2,4-dinitrobenzene,CDNB)对锦鲤鱼(Brocarded carp)的单一毒性和二元、三元混合体系联合毒性。用四种方法(毒性单位法(TU)、相加指数法(AI)、混合毒性指数法(MT)I和相似性参数法(λ))对联合毒性类型进行了评价。结果表明,3种硝基苯对锦鲤鱼的单一毒性大小顺序为:CDNB>M-DNB>P-NCB。P-NCB与M-DNB的联合毒性48小时之前为拮抗作用,48小时后为协同作用,P-NCB与CDNB的联合毒性类型为拮抗作用,而M-DNB与CDNB以及三元混合体系的联合毒性机制均为协同效应。

| Abstract: | The toxicities to Brocarded carp of single chemical and different mixture systems of para-nitrochlorobenzene(P-NCB)with m-dinitrobenzene(M-DNB)and chloro-2,4-dinitrobenzene(CDNB)according to equitoxcity ratio of 1:1 were determined respectively.Four methods including toxic unit,additional index,mixture toxic index and similarity parameter were used to evaluate the joint toxicity types of the three chemicals to Brocarded carp.The results indicated that the acute toxicity sequence was CDNB>M-DNB>P-NCB and the... |
