Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

EC number: 297-907-9 | CAS number: 93763-87-2 Substance formed by processing of chiefly oxidic material with lead and zinc content in a rotating furnace. Consists primarily of Al2O3, CaO, Fe, FeO and SiO2 with other nonferrous compounds as well as carbon.
Toxicity to terrestrial plants

Description of key information
The results of the terrestrial plant toxicity tests documented in this section, the results of the transformation/dissolution tests in aqueous media (IUCLID 5.6.) and of the aquatic toxicity tests in section 6 all consistently demonstrate the very limited solubility of slag, leead-zinc smelting.
Key value for chemical safety assessment
Additional information
Sags, lead-zinc smelting are very stable also in soils, and have no toxic effect on plants. The results on soil toxicity obtained with soluble or slightly soluble zinc compounds are not considered relevant for slags, lead-zinc smelting.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
