A "Manometric Respirometry Test" was conducted by Bayer Industry Services GmbH (2007) in accordance with EU-Method C.4-D and OECD TG 301 F in order to assess the ready biodegradability of the test substance. A suspension of the test item was inoculated and incubated for 28 d under aerobic conditions. During this period, degradation was followed by BOD determinations. After 28 days, 0.0% degradation was observed. Therefore, the test item is considered to be "Not Readily Biodegradable".

As no biodegradation (0%) was observed in a study on ready biodegradability it is not expected that a significant degradation would occur in a simulation test. The test substance is considered as non-biodegradable in surface water and sediment compartment. However, biodegradation is irrelevant as primary degradation step because immediate hydrolysis takes place.
