This work presents the determination of Glyphosate (GLY) and its biological degradation by-product, aminophosphonic acid (AMPA), in sediment samples collected in February (1a campaign), in June (2a) and November (3a) of 2019.The samples come from rivers/streams around the Itaipu Reservoir, on the Brazilian (BR) and Paraguayan (PY) sides. According to Table 1, it is possible to see the average percentage of occupation and land use. The samples are indicated with (a), (b) and (c) where group a covers areas possibly little impacted, group b with scenarios impacted by agriculture, but without the high presence of pesticides and group c with impact by agriculture and large amounts of pesticides.
