Description of key information
Additional information
The biodegradability of charcoal (Probe 2: C-Fix = 80.5%) was tested according to OECD guideline No. 301B (CO2 evolution test) and under GLP compliance.
The test item was tested in a concentration of 25 mg/L. As positive control, aniline was tested in parallel. The biodegradation of the test substance was determined by measuring the emitted CO2concentrations on test days 2, 4, 7, 9, 11, 14, 18, 23, during the 28-day test period and on day 29. The biodegradation for the whole test period was determined as <2%. Hence, charcoal (Probe 2: C-Fix = 80.5%) is considered not readily biodegradable. For the positive control, a degradation of 64% was achieved within 9 d, ensuring the validity of the test.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
