Biodegradation in water and sediment: simulation tests
Administrative data
Link to relevant study record(s)
- Endpoint:
- biodegradation in water: sediment simulation testing
- Data waiving:
- exposure considerations
- Justification for data waiving:
- the study does not need to be conducted because direct and indirect exposure of sediment is unlikely
- Transformation products:
- not specified
- 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:
- the study does not need to be conducted because the substance is highly insoluble in water
- Transformation products:
- not specified

Description of key information
No data on the biodegradation in simulation tests are available.
In accordance with Regulation (EC) No 1907/2006, Annex IX, Section
9.2.1.2 Column 2 the simulation test on ultimate degradation in surface
water does not need to be conducted if the substance is highly insoluble in
water. This has been demonstrated by the Key study (Ciba Specialty
Chemicals Corporation, USA, REPORT ON WATER SOLUBILITY,
Report no. GLP97010, 1997) according to EU MEthod A.6 (Water Solubility),
EEC Directive 92/69, A.1 (section 4.8). The water solubility of test
substance was determined to be < 40 µg/L at 20°C and therefore meets the
waiving criteria.
Furthermore, in accordance with Regulation (EC) No 1907/2006,
Annex IX, Section 9.2.1.4 Column 2, the sediment simulation testing
does not need to be conducted if direct and indirect exposure of sediment
is unlikey. No hazard regarding the envirionment has been identified.

Additional information
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.
