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.
Short-term toxicity to aquatic invertebrates

Description of key information
tests performed on eluate of slag, lead-zinc smelting according to standard OECD protocol show no short-term toxicity to Daphnids.
Key value for chemical safety assessment
Additional information
Slag from lead-zinc smelting is insoluble material. Daphnid tests, performed on an eluate of the slag made according to DIN 384141 part 4, and tested according to OECD 202, show very limited toxicity of the slag for the daphnids.
According to these data, slag, lead-zinc smelting should not be classified for aquatic toxicity.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
