A simple analytical method was developed to measure concentrations of glufosinate ammonium and its metabolites, 3-methylphosphinico-propionic acid (MPP) and 2-methylphosphinico-acetic acid (MPA), in field soil samples.
To determine the minimum quantification limit, samples were spiked at different levels (0.1, 0.5, and 1.0 mg/kg).
Soil samples were extracted with ammonium hydroxide solution 5% (v/v), concentrated, and reacted with trimethyl orthoacetate (TMOA) in the presence of acetic acid for derivatization.
The derivatives were quantified by gas chromatography (GC) using a flame photometric detector (FPD).
The linear correlation coefficients of glufosinate ammonium, MPP, and MPA in soil were 0.991, 0.999, and 0.999, respectively.
The recoveries of this method for glufosinate ammonium, MPP, and MPA in soil were 77.2–95.5%, 98.3–100.3%, and 99.3–99.6% with relative standard deviations (RSD) of 1.8–4.1%, 0.4–1.4%, and 1.3–2.0%, respectively.
Glufosinate ammonium dissipated rapidly in soil to MPA in hours and gradually degraded to MPP.
The half-life of glufosinate ammonium degradation in soil was 2.30–2.93 days in an open field.
In soil samples stored at −20°C glufosinate ammonium was stable for two months.
The results of this study should provide guidance for the safe application of the herbicide glufosinate ammonium to agricultural products and the environment.
