Ecotoxicological information

Toxicity to aquatic algae and cyanobacteria

Currently viewing:

Administrative data

Endpoint:
toxicity to aquatic algae and cyanobacteria
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 algae 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

Materials and methods

Principles of method if other than guideline:
ECOSAR v1.11 is a QSAR for organic substances which estimates the ecotoxicity based on structure-activity relationships.

Applicant's summary and conclusion

Conclusions:
The EC50 (96 hr) for algae was reported to be 124.4 mg/L
Executive summary:

No experimental data are available for the effect of the substance on the toxicity to algae. The QSAR, ECOSAR Program v1.11 was used to predict the toxicity. The QSAR is acceptable with restrictions. The EC50 (96 hours) for algae is estimated to be 124.4 mg/L in fresh water
