Abstract:
 To evaluate the safety of compound pesticide 82% metolachlor?metribuzin?2,4-D-ethylhexyl EC of metolachlor, metribuzin and 2,4-D-ethylhexyl in soybean, this study used an improved QuEChERS pretreatment method coupled with Ultra Performance Liquid Chromatography Tandem Mass Spectrometry (UPLC-MS/MS) and Gas Chromatography (GC) to determine metolachlor, metribuzin, 2,4-D-ethylhexyl and intermediate metabolite 2,4-D in soybean, immature soybean, soybean straw and immature soybean straw. The risk factors (Risk Quotients, RQ) of these pesticides were evaluated by comparing the national estimated daily intake with the acceptable daily intake. The results showed that the average recovery of metolachlor, metribuzin, 2,4-D and 2,4-D-ethylhexyl in samples were 72.3%-105.7%, and the Relative Standard Deviation (RSD) was 0.9%-14.0%. The limit of quantitation (LOQ) of metolachlor, metribuzin, 2,4-D and 2,4-D-ethylhexyl in soybean and immature soybean were repectively 0.02, 0.005, 0.005 and 0.005 mg?kg-1, in soybean straw was 0.04 and in immature soybean straw was 0.02 mg?kg-1. This method has been successfully applied to determine the concentration of metolachlor, metribuzin, 2,4-D-ethylhexyl and 2,4-D in soybean field test samples. Under the conditions of Good Agricultural Practices (GAP), the terminal residues of metolachlor, metribuzin, 2,4-D-ethylhexyl and 2,4-D in soybean, immature soybean, soybean straw and immature soybean straw were not detected. The National Estimated Daily Intake (NEDI) of metolachlor, metribuzin and 2,4-D for the general population was 0.083 73, 0.011 6 and 0.279 5 mg?(kg bw)-1, respectively, and the RQs were 1.33%, 1.41% and 44.36%, which showed that the application of 82% metolachlor?metribuzin?2,4-D-ethylhexyl EC compound of the three herbicides under GAP conditions had a lower health risk for consumers.
