Glyphosate and AMPA were analyzed in PM10 and soils from different landmanagement systems: agricultural soils under no-tillage with genetically modifiedannual crops (AG), agricultural soils under conventional tillage with annual crops (nonglyphosate-resistant) (AFG), and permanent grasses (PG) with no-tillage and noglyphosate application in the last 30 years. The percentage of detection wascalculated. AG had the highest glyphosate and AMPA percentage of detection, in soiland PM10 (100% in all cases). Similar results were found for AFG, except forglyphosate in soil (80%). In PG, no glyphosate was detected in soil but it was detectedin PM10 samples (83%) and AMPA was detected in soil (67%) and PM10 (100%)samples. The detection in PG suggests the entry of glyphosate and AMPA from othersites. The contents of glyphosate and AMPA in soil and PM10 were greater in AG thanin AFG and PG (p
