Description of key information
Additional information
The test item Tar wood was tested using a concentration of nominally 20 mg organic carbon/L (corresponding to 33.4 mg Tar wood/L) in test medium following OECD 301B and EU-Method C.4-C. Aniline was chosen as positive control.
Activated sludge was used as inoculum (concentration in the test 25.0 mg dry matter/L). The test was left running for 28 days.
All validity criteria were met. Degradation of the positive control was 65 % after eleven days.
The following data were determined for the test item Tar wood:
10-day-window: day 4 – 14
degradation at the end of 10-day-window 37 %
degradation at the end of the test 47 %
pass level following guideline: 60% at the end of 10-day-window
Therefore, regardless of the 10-day-window, Tar wood is not biodegradable following OECD 301B/EU C.4-C.
