Currently viewing:

Administrative data

Endpoint:
biodegradation in water: sediment simulation testing
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is highly insoluble in water

Applicant's summary and conclusion

Conclusions:
In accordance with REACH Annex XI, the sediment simulation testing (required in section 9.2.1.4) does not need to be conducted as the substance activated carbon does not contain any hydrogen available for dehydrogenation; thus there is no energy gain by enzymatic dehydrogenation, so further biodegradation of this molecule will not occur.
Executive summary:

In accordance with REACH Annex XI, the sediment simulation testing (required in section 9.2.1.4) does not need to be conducted as the substance activated carbon does not contain any hydrogen available for dehydrogenation; thus there is no energy gain by enzymatic dehydrogenation, so further biodegradation of this molecule will not occur.
