Resumen:
Glyphosate is the most widely used herbicide worldwide, in order to evaluate theoccurrence of this pesticide and its microbiological degradation product, theaminomethylphosphonic acid (AMPA), this study measured their presences infreshwater, sediments and suspended particulate matter (SPM) samples fromSuquía River basin in Córdoba, Argentina. From all the analyzed samples 35 %contained glyphosate, AMPA or both compounds. The concentrations were spreadin different percentages depending on the environmental matrices considered,ranging from 12 to 20 times higher of glyphosate and AMPA in sediment and SPMthan in water. The maximum concentrations found in water were 125 μg. l-1 ofglyphosate and 4.8 μg. l-1 of AMPA, in sediment 1882.3 μg. kg-1 and AMPA 266.1μg. kg-1 and in SPM 1570.7 μg. kg-1 of glyphosate and 684.9 μg. kg-1 of AMPA. The most polluted area came to be CM that is situated in a green belt zone, in second place are RP and SR, extensive agricultural areas. As regards the aquatic risk assessment in water and sediments, fish in LC and CM are threatened by theconcentrations of glyphosate in water; these values were below the levels ofconcern for wildlife however it is convenient to update the limits established for freshwater aquatic protection.
