Conclusions & Next Steps in RA

This fact sheet presents the approach for data gathering, data selection, and data aggregation to be used for derivation of the PNEC value for the soil environment based on the SSD. Because the ecotoxicity of nickel is mitigated by the long-term reactions with the soil (i.e., ageing) and the physico-chemistry of the soils (i.e., pH, clay content, organic matter content), it is highly recommended to age and normalize the ecotoxicity data for PNEC derivation using the available bioavailability models as described in the Fact Sheet 5.
