IMPROVE – Towards an IMPROVED framework for the ecological risk assessment of pesticide mixtures

IMPROVE aimed to compile existing knowledge and data and use a predictive model approach to identify combinations of pesticides were interactions are likely to occur and that thus are of particular high risk to aquatic biota and ecosystem processes. These mixtures where to be tested at different concentrations in higher-tier test systems that allow for the quantification of a set of ecologically relevant end points. IMPROVE aimed to develop (1) a guidance document with science-based monitoring strategies and (2) an electronic expert system that facilitates the consideration of pesticide combination effects in risk assessment.
