Improved exposure assessment in Dutch ditches

Research output: Contribution to conferencePosterProfessional


At present the exposure of the aquatic ecosystem to plant protection products is under-estimated in the Dutch registration procedure. Only spray drift is considered to be a relevant entry route in surface water. In reality drainage and surface run off may also be important routes. The EU registration procedure does take these routes into account. Construction of a Dutch ditch scenario with a 90th-percentile probability of occurrence exposure concentration, that considers the three relevant entry routes
