摘　　要：通过参照《化学农药环境安全评价试验准则》中化合物对环境有益生物,如鱼类、蚯蚓、家蚕、水藻类的急性毒性的测定方法,进行化合物SCU-2028的环境安全性评价.结果表明化合物SCU-2028对斜生栅列藻72 h的EC50值为7.872 mg/L,对斑马鱼96 h的LC50> 12 mg/L,对蚯蚓14 d的LC50> 40 mg/kg和对3龄家蚕96 h的LC50> 4800 mg/kg桑叶.这显示出化合物SCU-2028对鱼类、蚯蚓、家蚕、藻类均为低毒.By referring to the assay for determining the acute toxicity of compounds to environmental organisms, such as fishes,earthworms,silkworms and algaes in "environmental safety evaluation tests of chemical pesticides standards", the environmental safety of compound SCU-2028 was evaluated. The results showed that the EC50 value against algaes in 72 h was 7.872 mg/L,the LC50 value against fishes in 96 h was more than 12 mg/L, the LC50 value against earthworms in 14 d was more than 40 mg/kg and the LC50 value against silkworms in 96 h was more than 4800 mg/kg. This showed that compound SCU-2028 had low toxicity to environmental organisms.
