Although glyphosate is a heavily applied herbicide worldwide, the risk of environmental contamination through transport mechanisms of this substance is still not well documented. This work aimed to develop a new extraction method for an exact determination of glyphosate and AMPA in different soils, to investigate the time dependent behavior of glyphosate and AMPA in soils and to investigate the influence of soil erosion processes on the dissipation of glyphosate and AMPA. The developed method covers matrix effects of the most representative agricultural soil types of Austria but can be...
