摘　　要：以淡水微型生物群落作为受试靶生物,研究了米满(Tebufenozide)对淡水微型生物群落呼吸作用的影响.用五天耗氧量抑制强度(RΔDO5)来表征农药对淡水微型生物群落呼吸作用的影响,并探讨了十二烷基苯磺酸钠、腐殖酸和硝酸盐等共存物质对米满生物效应的影响.本方法的表征参数可以推广到其它农药或化学品的环境安全评价.The toxicity of tebufenozide on the aquatic organisms was studied with freshwater microbial community as target species. Restrain grade of five-day oxygen demand（RDO5）, was established to express the effect extent of tebufenozide on the respiration of freshwater microbial community. Meanwhile the effects of coexistence such as SDBS, humic acid and nitrate on the toxicity of tebufenozide were also studied. The experiment method and parameter established can also be introduced to the environmental assessments of other pesticides or chemicals.
