TI  - Development and application of a liquid chromatography-mass spectrometry method 
      to evaluate the glyphosate and aminomethylphosphonic acid dissipation in maize 
      plants after foliar treatment.

AB  - A simple and fast method has been developed and validated to measure glyphosate 
      (GLYP) and aminomethylphosphonic acid (AMPA), which were previously derivatized 
      with 9-fluorenylmethylchloroformate (FMOC-Cl), in maize plants using liquid 
      chromatography (LC) coupled to fluorescence (FLD) and electrospray ionization 
      mass spectrometry (ESI-MS) detection. The method has shown to be consistent, 
      reliable, precise, and efficient. Moreover, the limits of detection (LOD) and 
      quantification (LOQ) reached with the proposed method for GLYP and AMPA are lower 
      than the established maximum residue levels (MRLs). The validated method was 
      applied to quantify GLYP and AMPA in genetically modified (GM) maize foliar 
      treated with the herbicide. It has been found that the GLYP dissipation was 
      mainly due to the progressive dilution effect after herbicide treatment. Finally, 
      it was also observed that the GLYP residue dissipation trend in maize shoot 
      (leaves and stem) tissue determined by LC-ESI-MS matched that determined by 
      liquid scintillation.
