Measurement of Underivatized Glyphosate and Other Polar Pesticides in Mult Matrices Using Reversed-Phase Chromatography and Tandem MS
Glyphosate is a synthetic, broad-spectrum herbicide widely used in both agricultural and residential sectors. Glufosinate is naturally produced by plants but is also produced synthetically on an industrial scale. Both are degraded by bacteria in plants, soil and water, to Aminomethylphosphonic acid (AMPA) and 3-(methylphosphinico)propionic acid (MPPA), respectively.
The accurate quantitation of these compounds and other polar pesticides (2-hydroxyethyphosphonic acid (HEPA), N-acetylglufosinate, Ethephon, Fosetyl) at sub-ppb levels in surface water, and low-ppb levels in other matrices, have proven to be challenging, given their very polar nature.
