By focusing on the impact on ecosystems, MUSA aims at building up an efficient decision support tool integrating Environmental Risk Assessment (ERA) and Life 
Cycle Assessment (LCA) for contaminated soils management.   
   
1. Identifying and describing the similarities and discrepancies between   
Life Cycle Assessment (LCA) and Environmental Risk Assessment (ERA);   
   
2. Calculating uncertainty results associated for impact assessment   
on Ecosystems as a change in biodiversity for LCA and ERA   
   
3. Addressing the issue of speciation and bioavailability of metals in LCA and ERA    
   
4. Providing an approach integrating LCA and ERA for assessing impact of contaminated soils on ecosystems   
   
5. Applying the proposed methodology to the “Ronde Venen” Case   
Study.
