In this report new proposals for the aquatic effects assessment of plant protection products (pesticides) in the Netherlands are described for edge-of-field surface waters (drainage ditches) falling under the domain of the Plant Protection Product Regulation (pre-registration) and for water bodies falling under the domain of the Water Framework Directive (post-registration). These methods are developed on request of two Dutch ministries (Ministry of Economic Affairs, Agriculture and Innovation; Ministry of Infrastructure and Environment). They are based on specific protection goals proposed by the responsible risk managers of the Dutch ministries, the current European aquatic risk assessment procedures for plant protection products, state-of-the-art knowledge on the ecotoxicology of these chemicals and different aims/claims of the Plant Protection Product Regulation (1107/2009/EC) and the Water Framework Directive (2000/60/EC).
