Description of key information

HFC 227ea was found not readily biodegradable after 28 days under aerobic conditions.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

Under aerobic conditions 1% biodegradation was found for 8.49 mg/l HFC 227ea tested according to OECD Guideline 301 D (Ready Biodegradability: Closed Bottle Test) (Katsuura, 1993). This was supported by another Closed Bottle Test (OECD 301 D) in which 5% biodegradation was found for 17.4 mg/L HFC 227ea under aerobic conditions (Teufel, 1992).
