- W950373516 abstract "为了评价农药对土壤无脊椎动物种群的生态风险,采用OECD标准滤纸法和人工土壤法测定了10种常用农药对蚯蚓（Eisenia foetida）的急性毒性效应。采用滤纸法,48h测定结果表明,4种氨基甲酸酯类（异丙威、甲萘威、速灭威和丁硫克百威）和2种有机磷类（毒死蜱和哒嗪硫磷）农药对蚯蚓的急性毒性（其LC50值为3.50（2.77～4.44）～72.42（59.58～88.05）μg·cm-2）明显高于3种昆虫生长调节剂（噻嗪酮、虫酰肼和呋喃虫酰肼）和吡蚜酮对蚯蚓的急性毒性（其LC50值〉629.1μg·cm-2）。采用人工土壤法,14d测定结果表明,上述4种氨基甲酸酯类农药对蚯蚓的急性毒性（其LC50值为59.61（55.13～64.44）～134.1（127.0～141.5）mg·kg-1）明显高于上述2种有机磷类农药和其他农药对蚯蚓的急性毒性（其LC50值为193.0（180.1～206.8）～386.4（359.7～414.2）mg·kg-1）。上述结果表明,不同类型的农药对蚯蚓的毒性存在较大差异,且同一类型的不同农药品种对蚯蚓的毒性也存在较大差异。总体来看,氨基甲酸酯类农药比其他类型的农药对蚯蚓具有更高的毒性。根据《化学农药环境安全评价试验准则》,本研究采用人工土壤法测定的所有农药对蚯蚓均为低毒级。" @default.
