摘要：Neocaridina denticulata is a small freshwater shrimp indigenous to Korea. As an indigenous species has long- adapted to particular water environments,the species can be a suitable indicator to assess environmental risks caused by hazard chemicals in the particular site. Thus Neocaridina denticulata,a small freshwater shrimp indi- genous to Korea,is worth considering for a test species for such purpose. N. denticulata were exposed to pentachlorophenol sodium sll,sodium azide and ptassium dichromate using automatic flow through system for 96 hours. The 96 hr lethal concentrations (LCo) of these chemicals were cal- culated as 0.53士0.09 mg/L,2.40士0.61 mg/L and 1 .21士0.09 mg/L respectively and showed relatively small deviation from repetitive test results. When compared with the toxicity values of other species for each chemical, N. denticulata had moderate or high sensitivity to the toxicity of these chemicals. It can be concluded that N. denticulata is a good test species to evaluate acute toxicity of various hazardous chemicals.
