Occurrence of glyphosate and AMPA in an agricultural watershed from the southeastern region of Argentina por Lupi, Leonardo, Miglioranza, Karina Silvia Beatriz, Aparicio, Virginia Carolina, Marino, Damian Jose Gabriel, Bedmar, Francisco, Wunderlin, Daniel Alberto

“…The slight enrichment of pesticides observed from 25 cm depth to deeper layer, in addition to the alkaline pH along the profile, is of high concern about groundwater contamination. Sediments from pre-application period showed relatively lower pesticide levels (0.0053–0.0263 μg/g d.w.) than surface soil with a predominance of glyphosate, indicating a limited degradation. …”
