摘要

本研究的目的是为波多野研究所(HRI)组织的能力验证(PT)中使用的糙米样品中的目标农药提供可靠的浓度分配值。将糙米浸入农药溶液中,并使用 HRI 提供的喷雾干燥器制备能力验证测试样品。对 PT 样品进行了均匀性和稳定性评估,不均匀性和不稳定性导致的相对不确定性分别为 0.58 %-0.78 % 和 0 %-0.96 %。日本国家计量院(NMIJ)采用多种分析方法,包括日本官方分析方法、QuEChERS 和改进的 QuEChERS,结合同位素稀释质谱法,对目标农药的分配值进行了定量,以确保分析结果的可靠性。毒死蜱的 NMIJ 分配值为 0.065±0.004 mg/kg,二嗪农为 0.217±0.012 mg/kg,杀螟松为 0.138±0.008 mg/kg,马拉硫磷为 0.138±0.008 mg/kg。

A reliable quantification of organophosphorus pesticides in brown rice samples for proficiency testing using Japanese official analytical method, QuEChERS, and modified QuEChERS combined with isotope dilution mass spectrometry

The objective of the present study is to provide reliable concentration values as assigned values for target pesticides in brown rice samples used in proficiency testing (PT) organized by the Hatano Research Institute (HRI). The test samples for PT were prepared by immersing brown rice in the pesticide solution and using a spray dryer by the HRI. Homogeneity and stability assessments were performed for PT samples, and the relative uncertainties due to inhomogeneity and instability were 0.58 %–0.78 % and 0 %–0.96 %, respectively. Quantification for the assigned values of target pesticides by the National Metrology Institute of Japan (NMIJ) was carried out using the multiple analytical methods including Japanese official analytical method, QuEChERS, and modified QuEChERS, which were combined with isotope dilution mass spectrometry, to ensure the reliability of the analytical results. The NMIJ assigned values were 0.065±0.004 mg/kg for chlorpyrifos, 0.217±0.012 mg/kg for diazinon, 0.138±0.008 mg/kg for fenitrothion, and 0.138±0.008 mg/kg for malathion.
