AB  - In this study, a quick, easy, cheap, effective, rugged and safe (QuEChERS) 
      extraction technique was adapted to develop a simple sample treatment for 
      multi-residue pesticide analysis in milk samples. The proposed method is based on 
      liquid-liquid partitioning with acetonitrile followed by dispersive solid phase 
      extraction clean-up using primary secondary amine along with zirconia-coated 
      silica particles for extract purification. Identification and quantification of 
      30 pesticides was conducted via high performance liquid chromatography with 
      diode-array detection (HPLC-DAD). Recoveries were from 70 to 100% for the vast 
      majority of the analytes, with relative standard deviations less than 20% being 
      observed. HPLC-DAD provided suitable linearity, precision and accuracy. For 28 of 
      30 analytes in the study method limit of quantification values (mLOQs) comply 
      with the most recent European Union guidelines for the maximum residue levels 
      (MRLs) in milk. Negligible matrix effect was observed due to efficient extract 
      clean-up with ZrO2-based sorbents.
