【摘要】 应用超高效液相色谱-串联质谱法(UPLC-MS/MS)测定土壤中溴嘧氯草醚残留量,采用薄层层析法首次研究了溴嘧氯草醚在重壤土、中壤土和砂壤土中移动特性,为该药的环境风险提供数据支持。结果表明,溴嘧氯草醚在重壤土、中壤土和砂壤土中移动值(Rf)均为0.083,在3类土壤中溴嘧氯草醚属于不移动农药。在正常条件下,溴嘧氯草醚通过移动作用进入地下水而造成地下水污染的风险较小。更多还原

【Abstract】 The soil movement characteristics of SIOC0426 by thin layer chromatography were first investigated,including heavy loam soil, medium loam soil and sandy loam soil, which can provide data on the environmental risks of the pesticide. The residue of SIOC0426 in soil samples was analysed by ultra performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS). The results showed that the movement values(Rf) of SIOC0426 in heavy loam soil, medium loam soil and sandy loam soil were all 0.083. According to the results, the SIOC0426 belongs to a kind of immobile pesticide. Under normal conditions, the risk of groundwater contamination by SIOC0426 leaching into groundwater is small.更多还原
