  abstract = {{W}e report the spatial and seasonal distribution of organophosphorus herbicides, namely glyphosate ({GLYP}), glufosinate ({GLUF}), and their respective metabolites aminomethyl phosphonic acid ({AMPA}) and 3-(methylphosphinico)-propionic acid ({MPPA}), in the {R}ed {R}iver system ({N}orth {V}ietnam), a major water body in {S}outheast {A}sia. {T}he four compounds were measured at 34 sampling stations located from upstream to the estuary during the dry ({M}arch) and wet ({J}uly) seasons in 2019. {L}arge seasonal variations in herbicide concentrations were measured for the four analytes from upstream to the estuary, with the highest range of variations observed during the wet season. {I}n the surface waters of the {R}ed {R}iver, the maximum concentrations of {GLUF} (234 ng {L}-1), {GLYP} (565 ng {L}-1) and its metabolite {AMPA} (1329 ng {L}-1), occurred in the wet season. {T}hese values however, are lower than reported in other rivers worldwide. {I}n contrast, the estimated fluxes of these compounds in the {R}ed {R}iver water basin were very high during the wet season, i.e., up to 121, 50.2, 284, and 186 kg d-1 for {GLYP}, {GLUF}, {AMPA}, and {MPPA}, respectively. {D}uring both seasons, we observed correlations between the four compounds and ammonium ({NH}4+), suggesting that both nitrogen containing fertilizers and herbicides were applied in areas close to the river shore. {T}he concentrations and fluxes of the herbicides {GLYP}, {GLUF}, and their metabolites determined in the {R}ed {R}iver were compared to those recorded in other world river systems, such as the {G}aronne {R}iver ({F}rance), thus highlighting the importance of monitoring these compounds in surface waters.},
