Assessment of site-specific ecological risks of soil contamination can be used for determining the urgency of remediation and remediation goals, for spatial planning of land use at a site, and for developing measures to cope with soil contamination within a soil management system. This report describes a framework for site-specific ecological risk assessment taking into account land use, soil and contamination characteristics, and the ecology at the site. The framework is essentially a decision support system (DSS) consisting of three elementary steps: 1. definition of actual or desired landuse; 2. summing up site-specific ecological aspects related to this land use; 3. setting up instrumentation according to a Triad approach based on integrated analysis of different site-specific sources of information (environmental chemistry, toxicity, ecology). Three tiers of preciseness can be applied: qualitative, semi-quantitative and fully quantitative. The proposed DSS is a prototype which should be applied in practice to test its applicability and form of expression.
