AB  - An accurate method based on matrix solid-phase dispersion (MSPD), and gas 
      chromatography-mass spectrometry (GC/MS) was developed for determination of 
      phosmet residues and its metabolites (phosmet-oxon, phthalimide, 
      N-hydroxymethylphthalimide, and phthalic acid) in olive fruits. After testing 
      different sorbents and eluents for MSPD extraction, C(18) and acetonitrile were 
      found to be the most appropriate for clean-up of the samples, in terms of yields 
      and efficient removal of interfering compounds. All analytes were determined in 
      selective ion monitoring (SIM) mode following a derivatization step with 
      N,O-bis-trimethylsilyltrifluoroacetamide (BSTFA) containing 1% of 
      trimethylchlorosilane (TMCS), except for phosmet and phosmet-oxon which were 
      analyzed directly. The method showed suitable linearity (correlation coefficients 
      higher than 0.8919 for all the compounds) and suitable sensitivity (limit of 
      detection lower than 0.06mg/kg). It was successfully applied in the analysis of 
      olive fruits collected during the preharvest interval and olive oil. Phosmet 
      residues found in all samples were lower than the maximum residue limits 
      established by legislation (2mg/kg).
