Biodegradation in water: screening tests

In a valid follow-up study applying the OECD method 310 (Ready Biodegradability - CO2 in Sealed Vessels, Headspace Test), biodegradation of 60 % was reached after 23 d within a 12-days window, hence just failing the 10-days window (Fiebig/NOACK 2013) (see Chapter 4.1.2.1.3.). GC-analysis demonstrated >99% elimination of the original substance after 16 days.

A MITI II test (OECD 302 B, 28 d) apparently suggested only poor biodegradation with a low BOD of about 12 %. However, GC-analysis suggested significant primary structural changes under the test conditions (removal of the pristine test substance of about 93 %). As pointed out above, this study is considered unreliable and, therefore, has been disregarded for further assessment.
