Analytical methods to determine phosphonic and amino acid group-containingpesticides

A comprehensive view on the possibilities of the most recently developed ch romatographic methods and emerging techniques in the analysis of pesticides glyphosate, glufosinate, bialaphos and their metabolites is presented. The state-of-the-art of the individual pre-treatment steps (extraction, pre-co ncentration, clean-up, separation, quantification) of the employed analytic al methods for this group of chemicals is reviewed. The advantages and draw backs of the described analytical methods are discussed and the present sta tus and future trends are outlined. (C) 2001 Elsevier Science B.V. All righ ts reserved.
