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.
