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
