Brief Review Analytical Methods for the Determination of Glyphosate

Submit Manuscript | http://medcraveonline.com Glyphosate is a non-selective herbicide widely used in agriculture, which accounts for over 60% in the global market, providing a wide spectrum of action which enables an optimal control danin has plants [1-4]. Besides, this pesticide has low acute oral toxicity when compared to other herbicidas [5-7]. It is known that pesticide residues are widely used in chromatographic methods for quantifying the target analyte. However, many pesticides have high polarity, such as glyphosate, making it difficult to determine. Therefore, in many cases, it is used derivatization of these compounds, in order to make them suitable for a particular method in determining analítico [8-12]. It is noteworthy that even with derivatization often these residues require significant laboratory resources, as well as treatment processes of long, complex and expensive samples. So there is a clear need to develop simple, fast and effective methodologies that are able to determine and analyze high polarity pesticides [13,14]. The aim of this study was to develop brief review of the main analytical methodologies available in the analytical determination of glyphosate pesticide by chromatographic methods.
