1,1,1-trifluoroethane

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
