Additional information
The test item was tested using a concentration of nominally 20 mg organic carbon/L (corresponding to 29.7 mg test item/L) in test medium following OECD 301 Band EU-Method C4 -C.
Aniline was chosen as reference item. Activated sludge was used as inoculum (concentration in the test 25.9 mg dry matter/L) . The test was left running for 28 days. All validity criteria were met. Degradation of the reference item was 82 % after six days. The following data could be determined for the test item:
10-day-window: day 3 -13
degradation at the end of 10-day-window: 73 %
degradation at the end of the test: 89%
pass level: 60% at the end of 10-d-window
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
