Toxicity to aquatic algae and cyanobacteria
Administrative data
Link to relevant study record(s)
- Endpoint:
- toxicity to aquatic algae and cyanobacteria
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- other:
- Justification for type of information:
- A QSAR evaluation was carried out for the substance, to assess its potential for toxicity to fish. The logKow value of 6.13, which is itself a QSAR result, was used as input. The value for water solubility used in the assessment was 0.3 mg/l. The calculated 96h EC50 for green algae is above the aquatic solubility limit of the substance. The limit of water solubility (0.3 mg/L) is taken as the EC50 for PNEC derivation.
- Reason / purpose for cross-reference:
- data waiving: supporting information
Reference
Description of key information
The study does not need to be conducted because the substance is highly insoluble in water.
The limit of solubility of the substance in water is listed below.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 0.3 mg/L
- EC50 for marine water algae:
- 0.3 mg/L
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.
