Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Freshwater: chronic sediment data are available for one species of benthic nematode (Caenorhabditis elegans) with a reported NOEC growth of 1225 mg/kg d.w. (geometric mean of three NOECs from same study). The test was performed in unpolluted sediment with a background cadmium concentration of <1 mg/kg d.w. In addition, an in-situ recolonization study is also available for freshwater systems with a NOEC abundance reported of 115 mg/kg d.w. The test was performed in unpolluted sediment with a background cadmium concentration of 2.8 mg/kg d.w.
Marine water: chronic sediment data are available for one species of benthic marine crustacean (Leptocheirus plumulosus) with a reported NOEC growth, survival and reproduction of 1370 mg/kg d.w. The test was performed in unpolluted sediment with a background cadmium concentration of <0.001 mg/kg d.w. In addition, a field colonization study is also available for marine systems with a reported NOEC abundance and taxa richeness of 169 mg added Cd/kg d.w.

Additional information
Freshwater PNECsediment: Conclusion
The assessment of the freshwater PNECsedimentfor cadmium identified only two long-term ecotoxicity studies from the scientific literature. However, both the “Added” EqP (using partitioning coefficients and a robust aquatic toxicity database from the Cd RAR) and AF (using the lowest NOEC from a field colonization study) approaches produced consistent derivations for the freshwater benthic compartment. The resulting value is considered protective for EU freshwater ecosystems: freshwaterPNECadd, sediment of 1.80 mg/kg d.w. (equivalent to 0.40 mg/kg w.w.). It is emphasized that this is an added PNEC, i.e. natural background needs to be taken into account when characterising the risk from monitored data.
Marine PNECsediment: Conclusion
The assessment of the marinePNECsedimentfor cadmium identified only two long-term ecotoxicity studies from the scientific literature. However, an “Added” EqP (using partitioning coefficients and a robust aquatic toxicity database) approach provided a reliable derivation for the marine benthic compartment. The resulting value is considered protective for EU marine ecosystems:marinePNECsediment, addedof 0.64 mg/kg d.w. (equivalent to 0.14 mg/kg w.w.). It is emphasised that this is an added PNEC, i.e. natural Bg needs to be taken into account when characterising the risk from monitored data.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
