(52-12) PIERIS: the ecotoxicological database for plant protection products in Switzerland. Daniel, Otto*,1, Rudolf, Büchi1, Nathalie, Chèvre1, Umbricht, Michael1, 1 Swiss FederalResearch Station for Agroecology and Agriculture, Zürich-Reckenholz, Zürich, Switzerland ABSTRACT- In Switzerland, ecotoxicology has become an integral part of risk assessment and registration of plant protection products (PPP) since the year 2000. Based on the dossiers submitted by the industry with GLP studies and ecotoxicological reviews, we assess risks of PPP to organisms. Risk assessments evaluate effects of new active ingredients, changed composition of known active ingredients, modified formulations and PPP applied to new crops. The annual workload consists of 60-80 registration applications; 8-10 are new active ingredients. We developed the ecotoxicological database PIERIS (Pesticides and Intermediates Risk Information System). The database contains basic information on the product, environmental behaviour of active ingredients and intermediates of degradation, and ecotoxicological data on algae, crustaceans, fish, arthropods, birds, annelids and microorganisms. Ecotoxicological data include a brief test description, dose-specific observations and toxic potentials (e.g. LC50, NOEC). PIERIS calculates from crop-specific maximum application rates with specified scenarios PECs for aquatic and terrestrial ecosystems and TERs for different organisms. PIERIS has distinct output options and can create risk assessment reports, lists with PECs and TERs and overviews of the status of reports and deadlines for project management. The database allows the formulation of detailed queries to retrieve specific ecotoxicological data. An additional feature of PIERIS is the ability to calculate risk scores for different organism groups and to visualise risks with graphical representations.
