Biodegradation in water:
under test conditions no biodegradation observed

Additional information

The biodegradation potential of the substance in water was determined in a screening study according to OECD TG 301B (CO2 -Evolution Test) and in compliance with GLP criteria (BASF, 2014). In this study ca. 32 mg/L test substance was inoculated with activated sludge from a municipal sewage plant for 28 days under aerobic conditions. During the incubation period degradation was followed by determining the carbon dioxide produced. After the 28 -day incubation period less than 10% of the test substance was biodegraded. Based on these findings, the test substance is classified as not readily biodegradable.
