ABSTRACT
Objective To develop a method to screen and quantify 10 common herbicides (paraquat, diquat, glyphosate, glufosinate, cyanazine, atrazine, metazachlor, acetochlor, chlorsulfuron, and metsulfuron) in blood.Methods With acetonitrile-water solution[V (acetonitrile) ∶V (water) =3∶1]as protein precipitant, 10 common herbicides in blood were detected using ultra-high performance liquid chromatography-high resolution mass spectrometry (UPLC-HRMS).Results All the 10 herbicides had good linearity in their linear range (coefficient of determination R2≥0.993), with the recovery rates 67.4%-111.9%, the relative standard deviations 1.5%-10.8%, the accuracies 85.1%-106.1%, intra-day precisions 2.7%-13.5%, and inter-day precisions 3.3%-13.3%.Conclusion This method is easy to operate with high recovery rates.It enables rapid and accurate qualitative screening and quantitative analysis of various herbicides in blood simultaneously.
