Soil hydro-physical variables and crop residues determinate runoff soil loss, and glyphosate and AMPA concentration in the aqueous phase under simulated rainfall events por Sainz, Daiana Soledad, Behrends Kraemer, Filipe, Carfagno, Patricia, Eiza, Maximiliano Joaquin, Chagas, Celio Ignacio

“…Thus, this entails a serious risk of water contamination. The objectives of this study were to (1) test the hypothesis that the hydrological dynamics and sediment concentration related to surface runoff were conditioned by soil structure regardless of the presence of maize (Zea mays L.) crop residue and (2) assess the incidence of maize crop residue on glyphosate and aminomethylphosphonic acid (AMPA) concentration in runoff. …”

Assessing pesticide residue occurrence and risks in the environment across Europe and Argentina por Alaoui, Abdallah, Christ, Florian, Abrantes, Nelson, Silva, Vera, González, Neus, Gai, Lingtong, Harkes, Paula, Navarro, Irene, De la Torre, Adrián, Martínez, María Ángeles, Nørgaard, Trine, Vested, Anne, Schlünssen, Vivi, Aparicio, Virginia Carolina, Campos, Isabel, Pasković, Igor, Polić Pasković, Marija, Glavan, Matjaž, Ritsema, Coen, Geissen, Violette

“…There was a clear relationship between soils and crops in terms of contamination, but not between water and sediment. Portuguese soil (wine grapes) had the highest number of substances (12) with average concentrations (AC) varying between 1 and 162 μg/kg, followed by French (11 substances in wine grapes) (1≤AC≤64 μg/kg) and Spanish soils (9 substances in vegetables) (3≤AC≤59 μg/kg). …”
