AB  - A modified QuEChERS purification-liquid chromatography-tandem mass spectrometry 
      method has been developed to determine 51 pesticide residues with newly 
      established maximum residue limits (MRLs) in foodstuffs. Samples were extracted 
      with acetonitrile under citrate-buffered conditions and purified using a modified 
      QuEChERS method employing hydroxylated MWCNTs, SAX, and C(18). The limits of 
      quantification ranged from 0.2 to 9.8 microg/kg. Recoveries in ten different 
      foodstuffs ranged from 70.2% to 117.9%, with relative standard deviations between 
      2.3% and 19.9% at three spiking levels. This method was applied to analyze 352 
      market samples, detecting 14 pesticides in 97 samples. Notably, Afidopyropen, 
      cyantraniliprole, and fluxapyroxad residues in vegetables exhibited a consistent 
      pattern of higher levels in the spring and winter and lower levels in the summer 
      and autumn. Moreover, the risk assessments for acute and chronic dietary exposure 
      to the 14 detected pesticides indicated that the %ADI and %ARfD were well below 
      100%.
