The Toxic Test and Evaluation of Ether Pyrethroid to Fresh Water

本文对MTI-500,MTI-800及其他类型拟除虫菊酯杀虫剂进行鱼类毒性试验,测得24,48,72,96小时半致死浓度LC_(50).结果表明除了MTI-500,MTI-800外其他均为高鱼毒其中I-800毒性最低.

This paper selects MTI-500, MTI-800 and other type of pyrethroids as samples for the test of acute toxicity to fresh water fish.The LC_(50) of 24hr, 48hr, 72hr and 96hr was determined.The results show that, they exhibit high toxicity except MTI-500 and MTI-800.
