TI  - Large volume GC injection for the analysis of organophosphorus pesticides in 
      vegetables using the through oven transfer adsorption desorption (TOTAD) 
      interface.

AB  - A simple, rapid and sensitive multiresidue method has been developed for the 
      determination in vegetables of organophosphorus pesticides commonly used in crop 
      protection. Pesticide residues are extracted from samples with a small amount of 
      ethyl acetate and anhydrous sodium sulfate. No additional concentration and 
      cleanup steps are necessary. Analyses are performed by large volume GC injection 
      using the through oven transfer adsorption desorption (TOTAD) interface. The 
      calculated limits of detection for each pesticide injecting 50 microL of extract 
      and using an NPD are lower than 0.35 microg/kg which is much lower than the 
      maximum residues levels (MRLs) established by European legislation. Repeatability 
      studies yielded a relative standard deviation lower than 10% in all cases. The 
      method was applied to the analysis of eggplant, lettuce, pepper, cucumber, and 
      tomato.
