Guidance for summarizing and evaluating aquatic micro- and mesocosm studies. A guidance document of the Dutch Platform for the Assessment of Higher Tier Studies(Rijksinstituut voor Volksgezondheid en Milieu RIVMAlterraWageningen IMARESEC&C, 2008-03-10)A guidance document has been developed for ensuring that the test results required for the registration of pesticides be supplied in a uniform and transparent manner. This document is specifically directed at experiments carried out in artificial ecosystems in surface water (micro- and mesocosm studies). It has been developed by the Dutch Platform for the Assessment of Higher Tier Studies (PHTS), of which the Netherlands National Institute of Public Health and the Environment (RIVM) is the secretariat. Within the framework of the rules and regulations governing pesticide registration in the Netherlands, applicants (e.g. manufacturers of crop protection agents) are required to supply all necessary information to the Dutch Board for the Authorisation of Crop Protection Products and Biocides (Ctgb). Based on this information the Ctgb assesses whether the use specified for a specific product is acceptable. Complex and often extensive data on micro- and mesocosm studies can be a necessary part of the information provided. The Ctgb, an independent administrative body, requests various external institutes to summarize and evaluate these studies. Potential differences in the evaluator's methodology may lead to a lack of uniformity in the form and content of the summaries and evaluations and - occasionally - in the conclusions. These differences were the primary motivating factor for Ctgb to harmonize the evaluation reports of studies on ecosystems of surface water bodies. A secondary aim was to increase the transparency of the registration process.
