A column switching system for the determination of some polar pesticides and their main metabolites, such as aldicarb, aldicarb sulphoxide, aldicarb sulphone, carbofuran and 3-hydroxicarbofuran, in human urine has been developed. The limits of detection were between 0.3 and 1 microg/l. We used a simple solid-phase extraction with graphite carbon and a RPLC-LC analysis with UV detection yielding average recoveries between 84 and 110% (N=5) with RSD between 4 and 8%.
已开发出一种柱切换系统，用于测定人尿中的某些极性农药及其主要代谢物，如涕灭威、涕灭威亚砜、涕灭威砜、克百威和3-羟基克百威。检测限在0.3至1微克/升之间。我们采用了简单的石墨碳固相萃取和带紫外检测的反相液相色谱-液相色谱分析，平均回收率在84%至110%之间（N = 5），相对标准偏差在4%至8%之间。
