灭螨醌在柑橘上的残留降解及膳食风险评估
Residual degradation and dietary risk assessment of acequinocyl on citrus
摘要
Abstract
To address the lack of data on the residual degradation dynamics and dietary intake risk of acequinocyl 15%EW on citrus fruits,field residue tests were carried out using orah,shatangju,and kumquat as test materials.A high-performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS)method was used to determine the residual degradation dynamics of acequinocyl and hydroxyacequinocyl in different citrus varieties,and a dietary risk assessment was conducted.The results showed that acequinocyl and hydroxyacequinocyl exhibited good linear relationships(R2>0.99)in different citrus matrices.The limits of detection were 1.7-3.9 μg/kg and 1.0-1.2 μg/kg,respectively;the limits of quantitation were 4.5-7.9 μg/kg and 2.0-3.2 μg/kg,respectively;the recoveries were 79.4%—90.4%and 79.5%—92.6%,respectively,with RSD values of 2.4%—9.2%and 2.0%—9.0%,respectively.Except for the pulp of Shatangju,the degradation patterns of the two compounds in other parts of the three citrus varieties conformed to first-order kinetics,with half-lives of 17.5-24.8 d and 20.0-43.3 d,respectively.On the 14th and 28th days after application,the total residues of acequinocyl in the whole fruit of the three citrus varieties were 0.042-0.077 mg/kg and 0.013-0.046 mg/kg,respectively.The chronic and acute dietary exposure risks for all age groups were 0.03%—0.78%and 0.19%—2.84%,respectively.This study provides basic data for the rational use of acequinocyl on citrus and the establishment of maximum residue limits.关键词
