Short-term toxicity to aquatic invertebrates
Administrative data
- Endpoint:
- short-term toxicity to aquatic invertebrates
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model and falling into its applicability domain, with limited documentation / justification
- Justification for type of information:
- This substance is expected to hydrolyse rapidly to phenol in the environment. For the environmental assessment phenol PNECs have been used. However, in order to comply with the requirements of REACH, QSAR data on the substance is being provided since "rapid hydrolysis" is not a standard justification for waiving the endpoint.
