Notes:
Field desorption mass spectrometry was applied to the screening of aquatic environments for herbicides. The standard field desorption mass spectra of these compounds are also presented. The spectra of standard herbicides showed molecular and isotope ions, but fragment ions were not observed. The molecular ion was observed as the base peak. The spectra of the extracts of water showed positive responses at m/z 257 and m/z 344 corresponding to molecular ions of benthiocarb and oxadiazon. These herbicides were simultaneously confirmed when present in mixtures.
