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
