建立了尿液样品中阿特拉津(ATZ)及其代谢物脱乙基阿特拉津(DEA)、脱异丙基阿特拉津(DIA)、脱乙基脱异丙基阿特拉津(DEDIA)的气相色谱分析方法.样品经乙酸乙酯萃取、硫酸钠脱水、弗罗里硅土净化、浓缩后用气相色谱-电子俘获检测器分析.对样品萃取时的pH值等条件进行了优化,获得了较好的回收率.方法的检出限分别为DEDIA 0.002 5 mg/L,DEA、DIA、ATZ 0.005 mg/L.4种化合物在进样量为0.2～8 ng时与其峰面积呈良好的线性关系.利用该方法对阿特拉津生产厂工人的尿液样品进行了分析,尿液中4种化合物的质量浓度为:DEDIA 0.003～0.301 mg/L,DEA 0.005～0.011 mg/L,DIA 0.006～0.276 mg/L,ATZ 0.005～0.012 mg/L.
