用经处理的废水灌溉农作物有可能通过农业径流将源自废水的有机微污染物引入地表沃茨。为了确定是否化合物的存在下，处理后的污水灌溉水可以确定在农业径流，从污水灌溉和雨养耕地收集的地表径流样品进行了分析，为有机化合物的广谱。各种化合物被确定，似乎与灌溉处理废水。这些化合物包括人类药物（例如，卡马西平、吉非贝齐、卡立普多），个人护理产品成分（例如，驱虫剂、多环麝香）和烷基磷酸酯阻燃化学品。这些化合物中的大多数似乎以前没有在农业径流中报道过。这些化合物的浓度低于现有的少数已发表的水生毒理学数据;然而，不能排除它们在水生生物中引起更微妙影响的可能性。这些化合物都没有检测到从相同的领域在径流产生的降雨事件的样品中的广谱分析。
Irrigation of crops with treated wastewater has the potential to introduce effluent-derived organic microcontaminants into surface waters through agricultural runoff. To determine whether compounds indicative of the presence of treated effluent in irrigation water could be identified in agricultural runoff, surface runoff samples collected from effluent-irrigated and rain-fed cultivated fields were analyzed for a broad spectrum of organic compounds. A variety of compounds was identified that appeared to be associated with irrigation with treated wastewater. These compounds included human pharmaceuticals (e.g., carbamazepine, gemfibrozil, carisoprodol), personal care product ingredients (e.g., insect repellent, polycyclic musks), and alkyl phosphate flame retardant chemicals. Most of these compounds appear not to have been previously reported in agricultural runoff. These compounds were present at concentrations below the few published aquatic toxicology data available; however, their potential to elicit more subtle effects in aquatic organisms cannot be excluded. None of these compounds were detected by broad-spectrum analysis in samples from the same fields during runoff-producing rain events.
