Green onion and cabbage certified reference materials for the analysis of pesticide residues were issued by the National Metrology Institute of Japan, part of the National Institute of Advanced Industrial Science and Technology. Green onion and cabbage samples were grown so as to contain several kinds of organophosphorus and pyrethroid pesticides, and those were collected from a field in the Kochi Prefecture in Japan. The certification was carried out by using multiple analytical methods to ensure the reliability of analytical results; the values of target pesticides (diazinon, fenitrothion, cypermethrin, etofenprox, and permethrin for green onion and chlorpyrifos, fenitrothion, and permethrin for cabbage) were obtained by isotope dilution mass spectrometry. Certified values of target pesticides were 0.96-13.9 and 2.41-6.9 mg/kg for green onion and cabbage, respectively. These are the first green onion and cabbage powder certified reference materials in which organophosphorus and pyrethroid pesticides are determined.
葱和白菜的农药残留分析标准物质由日本国家计量研究院（National Metrology Institute of Japan），日本产业技术综合研究所（National Institute of Advanced Industrial Science and Technology）的一部分颁发。葱和白菜样本是为了包含几种有机磷和拟除虫菊酯类农药而种植的，这些样本是从日本高知县的一个农田中采集的。认证是通过使用多种分析方法来确保分析结果的可靠性来进行的；目标农药（葱中的二嗪磷、杀螟硫磷、氯菊酯、乙氰菊酯和氯菊酯，以及白菜中的毒死蜱、杀螟硫磷和氯菊酯）的值是通过同位素稀释质谱法获得的。葱和白菜中目标农药的认证值分别为 0.96-13.9 和 2.41-6.9mg/kg。这是首批测定有机磷和拟除虫菊酯类农药的葱和白菜粉标准物质。
