Description of key information

In the study on ready biodegradability a degradation rate of 79 % (20 mg/L) and 92 % (10 mg/L) were determined within 29 days for Androst-4-ene-3,17-dione.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Androst-4-ene-3,17-dione showed a degradation rate of 79 % (20 mg/L) and 92 % (10 mg/L) within 29 days and therefore has to be classified as "readily biodegradable".
