Effect of macrophytes and biochar on the performance of treatment wetlands for the treatment of agricultural runoffAgricultural runoff contributes greatly to the degradation of aquatic ecosystems, in particular by discharging a significant amount of fertilizers and pesticides. Current conventional methods used in agricultural environments are not sufficient to reduce the load of these pollutants in watercourses. One of the solutions to counter this problem is the incorporation of treatment wetlands into the agricultural landscape. My research is part of the project to mitigate agricultural pollution by greenery at Lac Saint-Pierre, initiated by "Unité de recherche en Gestion de l'Environnement et Nouvelles Technologies" (URGENT). It consists of using horizontal flow subsurfaced treatment wetlands (HSSF) for the treatment of agricultural runoff. Objectives: The general objective of this study is to optimize the use of the horizontal subsurfaced flow treatment wetland for the removal of chlorantraniliprole (CAP) and common agricultural pollutants from agricultural runoff. The first specific objective is to determine the performance of three local macrophytes planted in an HSSF for the removal of CAP and common agricultural pollutants. The second specific objective is to determine the effect of biochar addition in HSSF on the removal of CAP and common agricultural pollutants. To meet these objectives, the approach chosen is a mesocom experiment using horizontal subsurfaced flow treatment wetland, planted with three local plant species. Also, biochar is added to the main substrate, for a species of plant.
