Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The results of the transformation/dissolution tests in aqueous media (IUCLID 5.6.) and of the aquatic toxicity tests documented in this section 6 all consistently demonstrate the very limited solubility of slag, lead-zinc smelting. For this reason, the testing for soil toxicity is waived, because exposure to zinc ions in the pore water is anticipated to be very limited. Slag, lead-zinc smelting is very stable also in soils. The results on soil toxicity obtained with soluble or slightly soluble zinc compounds are not considered relevant for slag, lead-zinc smelting.
