Triazine herbicide residues were monitored in the rivers Adour, Danube, Garonne, Herault, Loire, Marne, Oise, Rhine, and Rhône from spring 1976 to fall 1977 to determine whether the continued use of the compounds resulted in accumulations of undesirable residues in the streams. Samples were generally collected monthly or bimonthly and analyzed for the parent compounds atrazine, simazine, terbumeton, terbuthylazine, and dealkylated metabolites GS 26571 (2-amino-4-etert-butylamino-6-methoxy-1,3,5-triazine) and G 30033 (2-amino-4-chloro-6-ethylamino-1,3,5-triazine). The compounds were extracted into dichloromethane and quantitated by gas chromatography (GC) with nitrogen-specific detection. Selected results were verified by GC with mass fragmentographic detection. Limit of detection was usually 0.4 mg/m3; 80 percent of all results were below 0.4 mg/m3, 14 percent were 0.4-1 mg/m3, 6 percent were 1-10 mg/m3, and 0.3 percent were higher than 10 mg/m3. Detectable residues were mainly atrazine from the downstream sampling sites. Residues usually peaked during June.
1976年春季至1977年秋季，对阿杜尔河、多瑙河、加龙河、埃罗河、卢瓦尔河、马恩河、瓦兹河、莱茵河和罗纳河中的三嗪类除草剂残留进行了监测，以确定这些化合物的持续使用是否会导致溪流中出现不良残留的积累。样品通常每月或每两个月采集一次，并对母体化合物阿特拉津、西玛津、特丁通、特丁津以及脱烷基代谢物GS 26571（2-氨基-4-叔丁基氨基-6-甲氧基-1,3,5-三嗪）和G 30033（2-氨基-4-氯-6-乙氨基-1,3,5-三嗪）进行分析。这些化合物用二氯甲烷萃取，并用带氮特异性检测的气相色谱法（GC）进行定量。选定的结果通过带质量碎片检测的气相色谱法进行验证。检测限通常为0.4毫克/立方米；所有结果的80%低于0.4毫克/立方米，14%为0.4 - 1毫克/立方米，6%为1 - 10毫克/立方米，0.3%高于10毫克/立方米。可检测到的残留主要来自下游采样点的阿特拉津。残留通常在6月达到峰值。
