Toxicity to aquatic algae and cyanobacteria

Currently viewing:

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
