对有机磷杀虫剂杀螟松及其降解产物3-甲基-4-硝基苯酚(3M4NP)进行了监测，其诱变剂形成潜力(MFP)比杀螟松更大。从东京都市区12条河流的41个地点采集了109个样品，在日本神奈川县靠近稻田的2条河流的4个地点采集了71个样品。固相萃取并用 N, O-双-(三甲基甲硅烷基)三氟乙酰胺 (BSTFA) 衍生化 3M4NP 后，通过 GC/MS 和选择离子监测测定杀螟硫磷和 3M4NP 的浓度。河水样品中杀螟松和 3M4NP 均低于 1 μg/L（杀螟松为 0 – 0.083 μg/L，3M4NP 为 0 – 0.156 μg/L），而河水样品中杀螟松和 3M4NP 分别达到 0.16 和 1.6 μg/L。溪流中还观察到季节性和区域波动。尽管如此，所有站点的 3M4NP 最高浓度均出现在 5 月下旬。此外，在检测到杀螟硫磷和/或3M4NP的样品中，3M4NP对56%和67%的河流和溪流样品的潜力贡献很大。这些结果有力地支持了同时监测各种农药及其降解产物、鉴定降解产物及其 MFP 以及表征它们在水净化过程中的行为的需要。
The organophosphate pesticide fenitrothion and its degradation product 3-methyl-4-nitrophenol (3M4NP), which possesses greater mutagen formation potential (MFP) than fenitrothion, were monitored. A total of 109 samples were collected from 41 sites of 12 rivers in the Tokyo metropolitan area and 71 samples were collected from 4 sites of 2 streams close to paddy fields in Kanagawa, Japan. The concentrations of fenitrothion and 3M4NP were determined by GC/MS with selected ion monitoring after solid-phase extraction and derivatization of 3M4NP with N, O-bis-(trimethylsilyl)trifluoroacetamide (BSTFA). Both fenitrothion and 3M4NP were below 1 μg/L (0 – 0.083 μg/L of fenitrothion and 0 – 0.156 μg/L of 3M4NP) in the river water samples, whereas fenitrothion and 3M4NP reached 0.16 and 1.6 μg/L, respectively, in the stream water samples. Seasonal and areal fluctuations were also observed in the streams. Nevertheless, the maximum concentration of 3M4NP appeared in late May at all sites. Furthermore, among the samples in which fenitrothion and/or 3M4NP were detected, 3M4NP largely contributed to the potential in 56% and 67% of the river and stream samples, respectively. These results strongly support the need for simultaneous monitoring of various pesticides and their degradation products, identification of degradation products and their MFP, and characterization of their behavior in water purification processes.
