SPE-HPLC-MS／MS 法测定人参及土壤中氟硅唑的残留及风险评估
Residue determination by SPE-HPLC-MS/MS and risk assessment of flusilazole in the ginseng and soil
摘要
Abstract
[Objective]To investigate flusilazole residues in ginseng and to conduct risk assessment.[Method]A solid phase extraction (SPE) and high performance liquid chromatography coupled withmass spectrometry (SPE-HPLC-MS/MS) method was developed to determine the residual dissipation andfinal residues of flusilazole 400 g·L-1 EC in ginseng root and soil at Fusong County and Ji ’an City in2011 and 2012.The dietary risk assessment was also conducted using the calculation of risk quotient(RQ).[Result and conclusion]The half-lives of flusilazole were 7.85 -9.94 d in root and 5.59 -7.13d in soil at spraying dosage of 90 g·hm-2.Final residues of flusilazole were below 0.043 3 mg·kg-1 inroot and below 0.037 5 mg·kg-1 in soil,and the risk was very low with 4.59 ×10 -5 (much less than 1)of a risk quotient,and the residues could be declined to the safe level over 35 days after spraying once ortwice at a dosage ranging from 60 to 90 g·hm-2.It is recommended that the MRL of flusilazole in ginsengshould be 0.05 mg·kg-1 temporarily,and its preharvest interval should be set at 35 days.关键词
