The environmental relevance of solid residues is described by their leach ability and toxicity. Short-term leaching tests and bioassays have been developed to assess their initial leaching and direct effect. Criteria set up for their reuse or disposal is based on these test schemes. However we are still uncertain to translate the obtained laboratory data into "real" systems. Main objective of the proposed study is to describe the significance of leaching processes for whole ecosystems. For this reason, multi-species test systems are proposed here for the first time to study the complex interaction between leaching processes and the biota. In contrast to single-species tests, these systems show a high degree of realism, in terms of size, diversity and food web interactions. It will be possible to identify indirect and secondary effects, which may be overlooked by conventional test procedures. This will help to develop environmentally more safe recycling products and applications.
