Dynamics of chloroacetanilide herbicides in various types of constructed wetlands
Original language description
Constructed wetlands for pesticide mitigation from agricultural runoff became widespread in the last decade. However, comparison of different types of CWs at one location is missing. Therefore, site by site comparison of three different types. ie. subsurface flow, surface flow and floating hydroponic root mat of CWs treating four chloroacetanilide herbicides acetochlor, s metolachlor, metazachlor, dimethachlor were carried out. All three planted systems are effective in removing the four herbicideswith removal efficiency higher than 92 percent after 9 days. The metabolites ethane sulfonic acids and oxanilic acids of the four herbicides peaked at 9 days in the surface flow CWs with soil, but all the metabolites did not peaked in the subsurface flow with gravel systems and the floating hydroponic root mat system after 21 days. All the detected metabolites account about 20 percent of the mother compounds. There is no noticeable metabolites accumulation in the control system with no plants and no su
