Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint:
biodegradation in water: sediment simulation testing
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is highly insoluble in water
other:
Justification for type of information:
Since slags are inorganic UVCB similar to natural rock, there is no need to perform any study on biodegradation
Endpoint:
biodegradation in water: simulation testing on ultimate degradation in surface water

Description of key information

No biodegradation of inorganic ionic substances

Key value for chemical safety assessment

Half-life in freshwater:
1 000 yr
at the temperature of:
20 °C
Half-life in freshwater sediment:
1 000 yr
at the temperature of:
20 °C

Additional information

Since slags are inorganic UVCB similar to natural rock, there is no need to perform any study on biodegradation. 1000 years taken as a default value for half-life in water and sediment
