Abstract: BACKGROUND Analytical constraints complicate environmental monitoring campaigns of the herbicide glyphosate and its major degradation product aminomethylphosphonic acid (AMPA): their strong sorption to soil minerals require harsh extraction conditions. Coextracted matrix compounds impair downstream analysis… read more here.
