Herbicide mitigation in microcosms simulating stormwater basins subject to polluted water inputs

► Stormwater basins (SWB) downstream of vineyards potentially mitigate herbicides. ► Microcosms mimicked physico-chemical conditions and hydraulic regime of SWBs. ► Mitigation efficiency of glyphosate, diuron and 3,4-dichloroaniline was investigated. ► Efficient sorption of herbicides in microcosms required a storage time of 6 h ► Herbicides in microcosm sediments were dissipated in 5 weeks.
