Biodegradation in water:
under test conditions no biodegradation observed

Additional information

The ready biodegradability of the test substance was assessed  in a CO2 Evolution Test following OECD guideline No. 301B (1993). The  biodegradation after 31 days was 0% (CO2 related to ThCO2). The DOC elimination degree after 31 days was 15%. Further, the biodegradability of the test substance was assessed in a Manometric Respirometry Test following OECD Guideline 301 F (1993). Elimination degree after 33 days was as "BOD of ThOD"14% and as "BOD of COD" 10%. Thus, the test substance is in both tests was poorly biodegradable (BASF, 1995) .
