在农业区的地表水中监测了许多杀虫剂。在三个水处理厂的雨水径流进水中发现阿特拉津、甲草胺、异丙甲草胺、氰嗪、甲草净、呋喃丹、利努隆和西马嗪。在这些工厂进行的研究以及实验室规模的研究表明，常规处理工艺的控制效果不佳。这些农药相对较高的吸附能力表明，颗粒活性炭对它们的控制具有成本效益。如果需要中等程度的去除率，以用于控制味道和气味的剂量施用粉末活性炭也可以有效。包括38个参考文献、图表和表格。

Numerous pesticides were monitored in surface waters in agricultural areas. Atrazine, alachlor, metolachlor, cyanazine, metribuzin, carbofuran, linuron, and simazine were found in the influent to three water treatment plants in stormwater runoff. Studies at these plants, together with bench-scale studies, demonstrated poor control by conventional treatment processes. The relatively high adsorption capacities of these agrichemicals indicate that granular activated carbon can be cost effective for their control. Powdered activated carbon applied at dosages used for the control of tastes and odors can also be effective if moderate percent removal is required. Includes 38 references, figures, tables.
