通过添加回收试验建立高效氟吡甲禾灵及其代谢物氟吡禾灵在油菜籽中的残留检测方法;2018-2019年,在河南济源、安徽合肥、浙江杭州、湖北武汉、湖南长沙、四川彭州、云南昆明、广西南宁等8地开展高效氟吡甲禾灵最终残留量试验,并对其进行膳食摄入风险评估。结果显示:采用乙腈超声提取,经弗罗里硅土层析柱净化,结合高效液相色谱检测油菜籽样品中高效氟吡甲禾灵,采用NaOH-甲醇混合溶液提取,经N-丙基乙二胺净化,结合液相色谱质谱联用检测油菜籽样品中氟吡禾灵,在0.05、0.30、3.00 mg/kg 3个添加水平下,高效氟吡甲禾灵和氟吡禾灵在油菜籽中的平均添加回收率分别为77%~87%和77%~100%,相对标准偏差分别...

A method for detecting the residues of haloxyfop-p-methyl and its metabolite haloxyfop-p in rapeseed was developed by recovery test. From 2018 to 2019, the final residue test of haloxyfop-p-methyl was carried out in Jiyuan of Henan, Hefei of Anhui, Hangzhou of Zhejiang, Wuhan of Hubei, Changsha of Hunan, Pengzhou of Sichuan, Kunming of Yunnan and Nanning of Guangxi, and the its dietary intake risk was then assessed. Ultrasonic extraction with acetonitrile, purification with Florisil column, combined with high performance liquid chromatography determination of haloxyfopp- methyl in rapeseed sam...
