Persistence and mobility of metazachlor and its metabolites in soils: Why transformation products pose a greater groundwater risk
Abstract Metazachlor is a widely used herbicide that is transformed into various metabolites that are often found in groundwater. To assess their mobility and persistence in the soil environment, batch experiments were performed for the parent compound and two most frequently occurring metabolites OA (479M04) and ESA (479M08), using representative soils of the Czech Republic. In addition, the concentrations of all three compounds and two additional metabolites (479M09 and 479M11) were measured during metazachlor de …
