Analysis and management of herbicidal mixtures in a high‐intensity agricultural landscape in Belgium

Abstract Water bodies located in anthropogenically influenced environments, such as agricultural landscapes, may be exposed to different chemicals simultaneously or sequentially. Yet, current environmental risk assessments focus on single active substances for unintended mixtures. For 3.5 years, the present study monitored the mixture of herbicides, within an intensively managed agricultural catchment, accompanied by a stewardship program. Twelve herbicides and one metabolite were monitored on a daily to sub‐daily basis, generating a unique, high temporal resolution data set, enabling an asses... Mehr ...
