AB  - Analytical method for the monitoring of residues of multiclass pesticides 
      (variable chemical structure and chromatographic behavior) in honey has been 
      optimized and in-house validated in the present study. Chemical confirmation of 
      35 selected pesticides (in-hive-treated pesticides and pesticides applied for 
      agricultural practices in vicinity of apiaries) has been successfully achieved 
      with the acetonitrile extraction/partitioning and cleanup by modified US EPA 
      solid-phase extraction (SPE) protocol following analysis on the GC/MS DRS 
      Pesticide Screener. The applied extraction procedure has given acceptable 
      recoveries with an associated precision (RSD) for selected pesticides within the 
      range as suggested by SANTE at MQL of 10 mug kg(-1). Potential matrix effect for 
      selected analytes was calculated by using honey from five different floral 
      sources. The optimized method was used to determine levels of pesticide residues 
      in honey samples randomly collected from 26 different apiaries in Pakistan. 
      Residues of nine selected pesticide (dichlorvos, mevinphos, ethalfluralin, 
      trifluralin, lindane, chlorpyrifos-methyl, dieldrin, profenofos, 4,4-DDE) were 
      frequently detected in the ranges of 3-48.8 mug kg(-1) in 26.9% of analyzed 
      samples (n = 26) and 15.3% of the studied samples exceeded maximum residue limits 
      (MRLs). In-hive-treated acaricides, i.e., coumaphos, tau-fluvalinate, and 
      malathion, were not detected in any of the analyzed honey samples.
