Description of key information
Readily biodegradable: 61% (O2 consumption) after 28 d (OECD 301F)
Key value for chemical safety assessment
Additional information
One experimental study is available investigating the ready biodegradability of Dub TGI 24. The study was conducted according to OECD 301F using non-adapted activated sludge from a municipal sewage treatment plant. Two test concentration were used, 100 mg/L which correspond to 302 mg ThOD and 20 mg/L which correspond to 60 mg ThOD. The ThOD of the first test substance concentration (302 mg ThOD) is clearly above the demanded value of at least 50 – 100 mg ThOD. Therefore, the additional approach with 20 mg test item (60 mg ThOD) was conducted. The biodegradation after 28 days was recorded as 40% at 100 mg/L and 61% at 20 mg/L. As the first test substance concentration (100 mg/L) failed the treshold with 302 mg ThOD, the second approach (20 mg/L with 60 mg ThOD) was used for evaluation of the biodegradation of the test substance. Therefore a biodegradation of 61% (O2 consumption) was reported after 28 days, but the 10-day-window was failed. Since the test substance is an UVCB substance and consists of structurally similar constituents with [e.g. different chain-lengths, degree and/or site of branching or stereo-isomers], sequential (instead of concurrent) biodegradation of the individual structures can take place. All can be considered as readily biodegradable. Thus, referring to Annex I to the OECD Guideline for Testing of Chemicals ‘Revised introduction to the OECD guidelines for testing of chemicals, section 3’ (OECD, March 2006), the 10-day window should not be applied to this UVCB substance . Based on the degradation of >60 % within 28 days the substance can be regarded as readily biodegradable.
