EC number: 206-996-5 | CAS number: 420-46-2
Toxicity to aquatic algae and cyanobacteria
Administrative data
- Endpoint:
- toxicity to aquatic algae and cyanobacteria
- Type of information:
- calculation (if not (Q)SAR)
- Remarks:
- Migrated phrase: estimated by calculation
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Results based on modeling. The model has given good results with fish and Daphnia and should therefore be reliable for algae. Also the substance is a gas with a boiling point of -47.4 deg. C and will partition into the air with minimal contact to algae
