液体クロマトグラフ-四重極飛行時間型質量分析計によるターゲットスクリーニング分析法を用いた水道水源中農薬類の存在実態の把握
We analyzed agricultural chemicals in water sources by target screening method using LC-Q/TOFMS. We detected many agricultural chemicals including pesticides analyzed in routine analysis such as bromobutide, isoprothiolane, orysastrobin, pyraclonil, pyroquilon and tefuryltrione. We also found bromacil, clothianidin, dinotefuran, furametpyr, ipfencarbazone, pyriminobac-methyl, thifluzamide and chlorantraniliprole, which are not recommended to analyze in routine analysis by the Ministry of Health, Labour and Welfare. Therefore, we do not have enough information for distribution of these chemicals in Japan because we don’t monitor these pesticides in routine analysis. These findings show that the target screening method using LC-Q/TOFMS is very useful to monitor a large number of agricultural chemicals simultaneously and to select chemicals for routine analysis.
