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 soil macroorganisms except arthropods

Description of key information
The results of the terrestrial toxicity test documented in this section demonstrate the very limited hazard of the slag for terrestrial organisms, e.g. earthworms. Further, transformation/dissolution tests in aqueous media (IUCLID 5.6.) and of the aquatic tests in this section 6 all consistently demonstrate the very limited solubility of slag, lead-zinc smelting.
Key value for chemical safety assessment
Additional information
Slags, lead -zinc smelting are very stable also in soils. There is no toxicity observed to earthworms. The results on soil toxicity obtained with soluble or slightly soluble zinc compounds are not considered relevant for slag, lead-zinc smelting.
