Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Test data is available on the acute toxicity of copper slag to fish. The results demonstrate that copper slag is not chronically toxic at the concentration tested: 48 h EC 10 94 mg/l or >1 mg/l
Key value for chemical safety assessment
Additional information
A reliable study (De Schamphelaere, 2010) was performed which assessed the chronic toxicity of mesocosm water extracts of five slags on Brachionus calyciforus (rotifer).The 48 h EC10 for copper slag in the range of 94 mg/l to >674 mg/l were found. Typical slag samples have been tested which were within the composition concentration range defined in IUCLID Section 1.2.
The calculated classification via Toxic unit approach (Higher Tier Arche CLP Tool) resulted in No chronic classification for the UVCB substance.
Based on this result, the related criteria provided the estimated value for chronic (long term) toxicity to aquatic invertebrate (see EU CLP Annex I Table 4.1.0):NOEC (for crustacea) >1 mg/l
Using a weight of evidence approach, the lowest short-term toxicity of copper slag to invertebrates is greater than 1 mg/l.
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).
