摘要
本文研究了7种常见拟除虫菊酯对4种鱼类、水蚤、藻类的毒性。结果表明:拟除虫菊酯对所有试验生物均属高毒,其中水蚤最为敏感,藻类最不敏感,而鱼类(除泥鳅)的敏感性相近,α-氰基和卤族元素会增加拟除虫菊酯对水生生物的毒性,由于商品中所含溶剂二甲苯和乳化剂农乳2201的毒性比试验中原药所用溶剂丙酮的毒性高,商品中助溶剂的毒性应加以考虑。
The toxicity of 7 quasi—pyrethrins(QPs)to 4 kinds of fish, water flea and algae has been studied. The results indicated that QPs is high toxic to all kinds of tested beings,in which water flea is the most sensitive, algae is the most insensitive and fishes (except loach) have similar properties. Cyanogen and halogen family can increase the toxicity of QPs to aquatic beings. Due to the high toxicity from solvent xylene and emulsion 2201 compared with acetone solvent,it should be considered carefully the toxicity of solvent promoters.
