Ecotoxicological Serious Risk Concentrations for soil, sediment and (ground)water: updated proposals for first series of compounds

The Intervention Value for soil and groundwater is based on the integration of a separately derived human toxicological Serious Risk Concentration or SRChuman as well as an ecotoxicological Serious Risk Concentration or SRCeco. This report presents proposals for updated SRCseco for the first series of compounds. For substances for which MPCs/NCs have been derived between 1990 and now, the same data are used to derive the SRCeco. Together with the derivation of the SRCeco, also a new MPC is derived, according the most recent guidelines as summarised in this report. The information in this report is used in the technical evaluation of Intervention Values for soil, sediment and groundwater, RIVM report 711701 023.
