The measured concentrations can be compared with own measurements and thresholds* for pesticide active substances in surface waters valid during the monitoring period.
*The considered thresholds are
Field-based Acceptable Concentrations (ACfield): The threshold for maximum concentrations of primarily invertebrate-toxic pesticides derived on the basis of the Kleingewässermonitorng data collected here
Regulatory Acceptable Concentrations (RAC): The threshold for maximum concentrations derived by the German Federal Environment Agency (Umweltbundesamt - UBA) within the framework of plant protection product authorisation - see Methods/Analysed Substances
Annual Average-Environmental Quality Standards (AA-EQS): The threshold for acceptable annual average concentrations according to the Water Framework Directive (list of priority substances and river basin-specific pollutants)
Maximum Acceptable Concentration-Environmental Quality Standards (MAC-EQS): The threshold for maximum concentrations under the Water Framework Directive (list of river basin-specific pollutants)
