Workshop on Bioaccumulation: sediment test using benthic oligochaetes

The presented report gives a description of the results of the international workshop 'Bioaccumulation: Sediment test using benthic oligochaetes', held at Hochheim/Main, Germany, on April 26-27 1999. Scientists and experts from industry, academia and governmental agencies in the field of assessment of bioaccumulative, sediment-associated contaminants came together for a workshop held in Hochheim/Main, Germany, on April 26/27, to discuss the guideline proposal: Egeler Ph., Knacker Th., Roembke J., Schallnass H.-J., Meller M., Studinger G., Franke C. and Nagel, R. (1997). Bioaccumulation: Sediment test using benthic oligochaetes. Proposal for a draft guideline according to OECD format. 2nd, revised version. German Federal Environmental Agency (Umweltbundesamt) Berlin. Submitted to OECD, Paris, for revision. This draft guideline was based on the results of a research and development project on a standardisable method for the determination of bioaccumulation in sediment dwelling organisms (UBA-F+E 106 03 106/03; UBA Text 2/99) and conducted at ECT Oekotoxikologie GmbH, Floersheim/Main, Germany. The objective of the workshop was to review and refine methodological and scientific aspects of the proposed draft guideline. Questions concerning choice of test species, sediment ageing, duration of the test, and application of the test guideline were discussed. Furthermore, the organisation of an international ring test as well as further steps for the draft test guideline to be implemented in international guideline programs were considered. The proposed method was accepted in general. Recommendations regarding scope and application of the test, test species, and on details of test performance were given and will be included in the revised draft guideline document, which is presented in this report.
