Biodegradation in water and sediment: simulation tests
Administrative data
Link to relevant study record(s)
- Endpoint:
- biodegradation in water: sediment simulation testing
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because direct and indirect exposure of sediment is unlikely
- Justification for type of information:
- In accordance with Column 2 adaptation statement of REACH Annex IX, sediment simulation testing, information requirement 9.2.1.4 does not need to be conducted as direct and indirect exposure to sediment is unlikely. The test substance entering the water is not likely to sorb onto suspended solids and sediment based upon the measured log Pow (CSR section 1.3 Physico-Chemical Properties), mitigating exposure to sediment.
- Transformation products:
- not measured
- Endpoint:
- biodegradation in water: simulation testing on ultimate degradation in surface water
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- other:
- Justification for type of information:
- Degradation testing shall be proposed by the registrant if the chemical safety assessment according to Annex I indicates the need to investigate further the degradation of the substance and its degradation products. The chemical safety assessment conducted on this substance and attached to section 13 of the dossier indicates no concern at current and anticipated supply volumes. As such it is considered that there is no need to undertake simulation testing on ultimate degradation in surface water, as listed in section 9.2.1.2 of column 1 of REACH Annex IX.
- Transformation products:
- not measured

Additional information
Simulation testing on ultimate degradation in surface water
Degradation testing shall be proposed by the registrant if the chemical safety assessment according to Annex I indicates the need to investigate further the degradation of the substance and its degradation products. The chemical safety assessment conducted on this substance and attached to section 13 of the dossier indicates no concern at current and anticipated supply volumes. As such it is considered that there is no need to undertake simulation testing on ultimate degradation in surface water, as listed in section 9.2.1.2 of column 1 of REACH Annex IX.
Sediment simulation testing
In accordance with Column 2 adaptation statement of REACH Annex IX, sediment simulation testing, information requirement 9.2.1.4 does not need to be conducted as direct and indirect exposure to sediment is unlikely. The test substance entering the water is not likely to sorb onto suspended solids and sediment based upon the measured log Pow (CSR section 1.3 Physico-Chemical Properties), mitigating exposure to sediment.
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.
