Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Discussion (screening testing)

The test item (charcoal) 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.

The following information is taken into account for any hazard / risk / persistency assessment:

The biodegradability of charcoal (Probe 2: C-Fix = 80.5%) was tested according to OECD guideline 301B (CO2evolution test) and under GLP compliance.

Biodegradation in water: under test conditions, no biodegradation was observed.

Discussion (simulation testing)

Simulation testing on ultimate degradation in surface water and sediment simulation testing is not needed, as charcoal, coconut shell is highly insoluble in water (see IUCLID section 4.8).
