Abstract

This report is the result of the second sub-project of the project "Setting integrated environmental quality objectives", called exotic metals". These trace metals are antimony, barium, beryllium cobalt, molybdenum, selenium, thallium, tin and vanadium. This report is an integration of three activities, published in separate reports: 1. derivation of Maximum Permissible Concentrations (MPC's) and Negligible Concentrations (NC's) for water, sediment, and soil based on ecotoxicological data. 2. derivation of partition coefficients in order to apply the equilibrium partitioning method. 3. gathering information about background levels in soil, ground water, and surface water. In this report the MPC's and NC's for the different compartments are coordinated to one another using the equilibrium partitioning method. Also the coordinated MPC's and NC's are compared with the related background concentrations.
