Ecotoxicological information

Short-term toxicity to fish

Currently viewing:

Administrative data

Endpoint:
short-term toxicity to fish
Type of information:
(Q)SAR
Adequacy of study:
supporting study
Study period:
2012
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
As the substance is a gas, measured data for the toxicity to fish are not available. In the place of measured data, predicted data using the QSAR model ECOSAR v.1.11. The substance is within the profile of the model and so the results are considered reliable
Justification for type of information:
QSAR prediction: migrated from IUCLID 5.6

Data source

Reference Type:
other: QSAR predicted data
Title:
Unnamed

Materials and methods

Principles of method if other than guideline:
ECOSAR is a QSAR for organic substances which estimates the ecotoxicity based on structure-activity relationships.

Results and discussion

Effect concentrations
Duration:
96
Dose descriptor:
LC50
Effect conc.:
672.6 mg/L
Remarks on result:
other: Predicted value

Applicant's summary and conclusion

Conclusions:
The 96 hr LC50 for fish is predicted to be 627.6 mg/L
Executive summary:

No experimental data are available for the effect of the substance on the short term toxicity of fish. The QSAR, ECOSAR Program v1.11 was used to predict the toxicity. The QSAR is acceptable with restrictions. The LC50 (96 hours) for fish is estimated to be 627.6 mg/L in fresh water
