Improving EU-risk assessment of toxicants for aquatic communities by considering competition on the population and community level

Objective

At present prospective risk assessment (RA) of toxicants is based on laboratory single-species tests and field test systems used in regulatory testing (91/414/EEC). Retrospective effects of contaminants are assessed by field monitoring (2000/60/EEC). The EU-SETAC workshop EPIF (France, 2004) identified a gap between the results of prospective and retrospective RA: Prospective RA should be improved by integrating environmental parameter. Competition was identified as such a parameter as it is ubiquitous present in natural populations and communities. Hence, there is an urgent need to incorporate this parameter into future RA. Also recent papers of the applicant and studies of other authors indicate the great importance of competition for forecasting chronic effects of toxicants on the community level. However, it remains the question on how to integrate competition in RA. In the light of this situation the aim of the project INTERACT is to improve the scientific basis of risk assessment concerning the parameter competition. To achieve this, investigations of the role of competition will be conducted on three levels of biological organisation: (i) a one-species system of aquatic invertebrates (ii) a two-species system (iii) and a multi-species mesocosm system with a nearly natural aquatic invertebrate community. The expected major outputs of INTERACT will be: (a) basic ecotoxicological knowledge about the interaction of toxicants and competition. On the basis of this mechanistic understanding additional outputs of the project will be (b) support for the interpretation of the above-mentioned regulatory tests and (c) of field monitoring data from retrospective RA according the EU water framework directive. The applicant has a strong interest to conduct his work at the working group Effect propagation at the UFZ as this group is an international accepted in this field and organized the EU EPIF workshop on this topic as mentioned above.
