In this report the proposals for the prospective (underlying Regulation 1107/2009/EC) and the retrospective (underlying the Water Framework Directive) aquatic effect assessment for plant protection products (pesticides) as described in Alterra Report 2235 are evaluated by applying the proposed procedures to a number of realistic cases (neonicotinoid insecticide, pyrethroid insecticide, triazinone herbicide, mitosis inhibiting herbicide, pyridinamine fungicide and cyano-acetamide fungicide). The examples presented in this report can be used as an illustration how the effect assessment schemes as described in Alterra Report 2235 need to be applied in decision making. Furthermore, the Regulatory Acceptable Concentrations (RACs) derived for these example cases on the basis of the new effect decision trees are compared with their Predicted Environmental Concentrations (PECs) provided by the Exposure Working Group and calculated on the basis of the new Dutch ditch exposure scenario.
