A new monitoring system was established for the determination of 90 pesticides and 10 pesticide degradation products in river water. The pesticides consisted of 18 fungicides, 30 insecticides, and 42 herbicides. The pesticides were extracted with a solid-phase, styrene-divinylbenzene copolymer, eluted with acetone, hexane, and ethyl acetate, and determined by gas chromatography/mass spectrometry. Overall recoveries ranged from 72 to 118%. The limits of detection were 0.01-0.1 microgram/L. This system determines most of the pesticides used in Japan and was successfully applied to practical monitoring of water polluted with pesticides and related compounds.
建立了一种新的监测系统，用于测定河水中的90种农药和10种农药降解产物。这些农药包括18种杀菌剂、30种杀虫剂和42种除草剂。采用苯乙烯-二乙烯基苯共聚物固相萃取这些农药，用丙酮、己烷和乙酸乙酯洗脱，然后通过气相色谱/质谱法进行测定。总体回收率在72%至118%之间。检测限为0.01 - 0.1微克/升。该系统能测定日本使用的大部分农药，并成功应用于受农药及相关化合物污染水体的实际监测。
