- A new eco-friendly method was developed for detecting low levels of four herbicides, specifically glyphosate, glufosinate, and their main metabolites, using solid-phase extraction with Chelex-100 resin and ultra-high-performance liquid chromatography paired with mass spectrometry.
- The method was validated in various water types, achieving recovery rates between 80.1% and 109.4%, with low detection limits ranging from 0.70 to 4.7 ng/L for the herbicides and metabolites.
- Successful application of this method in surface waters from the Red River Delta revealed significant concentrations of herbicides and metabolites, highlighting its effectiveness for monitoring environmental water quality.
