The test item is not readily biodegradable. Within 28 days only 50 % of
the test substance was degraded in a test conducted according to the EU
Method C.4-D (Determination of the "Ready" Biodegradability - Manometric
Respirometry Test)(Bayer AG, 1994).
Within 28 days a degradation of 73 % was determined for the test item
according to the OECD Guideline 302 C. Therefore the test item is
considered to be "Inherently Biodegradable" (Currenta, 2009).
A test on ready biodegradability showed that 50 % of the substance is degraded within 28 days. These results show that the substance is not readily biodegradable, but additionally provided evidence from an inherent test show that the substance can be degraded in sewage treatment plants. The substance is not readily biodegradable but inherent biodegradable (Bayer AG, 1994; Currenta, 2009).
The ready biodegradability of the substance was determined according to
the EU method C.4 -D (Determination of the "Ready" Biodegradability -
Manometric Respirometry Test) with the following result (Bayer AG,
1994): 50 % degradation after 28 days.
The inherent biodegradability was determined according to the OECD
Guideline 302 C (Inherent Biodegradability: Modified MITI Test (II)) and
results in 73 % degradation within 28 days (Currenta, 2009).
Based on these results, the substance is considered to be "Not Readily
Biodegradable", but "Inherently Biodegradable" .
