Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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.
