  • [Objective] To establish a rapid qualitative method for detecting dichlorvos and omethoate in biomaterials.

    [Methods] Dichlorvos and omethoate in gastric juice and blood samples were extracted by dichloromethane and evaporated using nitrogen stream. The residues were dissolved with dichloromethane and detected by gas chromatography-mass spectrometry (GC/MS). Indicators of sample pre-treatments and GC/MS conditions were described.

    [Results] The detection of dichlorvos and omethoate in biomaterials could be finished in 60 min. A qualitative conclusion was drawn by comparing the total ion chromatograms and the mass spectrums of the samples with the standard mass spectra.

    [Conclusion] The method can rapidly and accurately identify dichlorvos and omethoate in gastric juice and blood samples.
