AB  - The monitoring of food quality and safety requires a suitable analytical method 
      with simultaneous detection in order to control pesticide and herbicide residues. 
      In this study, a novel analytical method, referred to as "dispersive solid-liquid 
      extraction", was applied to monitor seven sulfonylurea herbicides in 
      strawberries. This method was optimized in terms of the amount of C(18) and the 
      volume of added water, and it was validated through satisfactory linearities 
      (R(2) > 0.99), recoveries of 70% to 84% with acceptable precisions, and limits of 
      quantification lower than the maximum residue limits for the seven sulfonylurea 
      herbicides in strawberries. The cleanup efficiency of the dispersive solid-liquid 
      extraction technique was compared to that of the QuEChERS- ("quick, easy, cheap, 
      effective, rugged and safe") based method with dispersive solid phase extraction. 
      The recoveries of the former were found to be comparable to those involving 
      QuEChERS C(18) cleanup (recoveries of 74%-87%). The method was used to determine 
      sulfonylurea herbicide residues in ten strawberry samples. None of the samples 
      had herbicide residues higher than that of limit of quantifications (LOQs) or 
      maximum residue limits (MRLs). The results suggest that the dispersive 
      solid-liquid extraction method combined with liquid chromatography-tandem mass 
      spectrometry (LC-MS/MS) is effective for the analysis of sulfonylurea herbicide 
      residues in strawberries.
