摘　　要：Mexel®432作为一种新型生物抑制剂,可治理电厂冷却水循环系统管道中的污损生物。本研究采用半静水实验方法研究了Mexel®432对3种经济型底栖生物:皱纹盘鲍(Haliotis discus hannai)、光棘球海胆(Mesocentrotus nudus)和日本蟳(Charybdis japonica)的96 h急性毒性效应。结果表明,Mexel®432对3种生物的毒性存在明显的时间-效应和剂量-效应关系。Mexel®432对皱纹盘鲍、光棘球海胆及日本蟳3种生物的96 h半致死浓度(LC50)分别为8 mg/L、11 mg/L、186 mg/L,安全浓度(safety concentration,SC)为0.80 mg/L、1.10 mg/L、18.60 mg/L。3种底栖生物对Mexel®432的毒性敏感性强弱依次为皱纹盘鲍>光棘球海胆>日本蟳。Mexel®432,as a new biological inhibitor,can be used to treat biological filth in the pipes of cooling water circulation system in power plants.In this study,the acute toxicity of Mexel®432 on three common marine economic organisms:Haliotis discus hannai,Mesocentrotus nudus,Charybdis japonica was studied by semi-static water experiments.The results showed that there was a significant time-effect and dose-effect relationships between the toxicity of Mexel®432 to three organisms.The median lethal concntrations of Mexe®l432 were 8 mg/L,11 mg/L and 186 mg/L,and the safe concentrations were 0.80 mg/L,1.10 mg/L and 18.60 mg/L,respectively.After stress,the toxicity of Mexel®432 to the three marine organisms was Haliotis discus hannai>Mesocentrotus nudus>Charybdis japonica.
