| 摘 要： | 测定了2,4-二硝基甲苯(2,4-DNT)与5种硝基苯衍生物对发光菌的单一毒性和在等剂量下二元混合物的联合毒性.采用毒性单位(TU)、相加指数(AI)、相似性参数(λ)和混合毒性指数(MTI)进行联合毒性评价,结果表明,5种二元混合物的联合作用均为协同作用;比较了不同对位取代基对混合物协同作用强弱的影响,采用混合毒性指数的评价结果与其它3种方法略有不同,但在以2,4-DNT为底物的二元混合体系中,对硝基氯苯的协同作用最弱.

| Abstract: | The toxicities of each and their binary mixtures of 2 ,4-DNT and five derivatives of nitro benzenes to vibrio fischeri were determined respectively. Toxicity unit ( TU ) , additive index ( AI ) , similarity parameter (λ) and mixture toxicity index( MTI ) were used to evaluate the joint toxicity. The results show that the five binary mixtures showed all synergistic action. The abilities of synergistic action of the five mixtures were compared. The result by MTI was a little different from those by other three methods , but in general , when mixed with 2 ,4-DNT , p-chloronitrobenzene had the weakest synergistic action. |
