Description of key information

The test substance is not readily biodegradable according to OECD criteria. The test substance is poorly biodegradable

Key value for chemical safety assessment

Additional information

In a GLP guideline study conducted in compliance with OECD 301B the ready biodegradability of the test substance was tested. Based on the determined CO2 evolution no biodegradation within 28 days was detected (RCC Ltd., 2002b). The result is supported by a second study set up according to OECD guideline 301C. The O2 consumption of activated sludge was recorded for 28 days and a degradation rate of 0 -3 % was determined (Ciba Specialty Chemicals Inc., 2002).
