Rapid GC-FPD determination of organophosphorus pesticide residues in Sicilian and Apulian olive oil

摘要: Abstract A simple and quick method for the determination of dimethoate, parathion-methyl, fenthion, parathion-ethyl, methidathion in olive oil is described. Analysis was carried out using GC (capillary column 5 m × 0.32 mm × 0.45 μm) with aspecific detector (FPD), after sample extraction acetonitrile. No cleanup necessary because there were no interferences chromatogram. Recoveries five pesticides at three fortification levels (1.0, 0.2 0.05 mg/kg) range 78–97%. Seventy-nine samples collected from Sicilian Apulian individual growers during 2002–2003. Only 16% contained fenthion concentrations ranging 0.09 to 0.73 mg/kg; other detected 79 samples.
