Ecotoxicological information

Short-term toxicity to aquatic invertebrates

Currently viewing:

Administrative data

Endpoint:
short-term toxicity to aquatic invertebrates
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 aquatic invertebrates 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

Applicant's summary and conclusion

Conclusions:
The 48 hr LC50 to daphnia was predicted to be 307.5 mg/L
Executive summary:

No experimental data are available for the effect of the substance on the short term toxicity of invertebrates.The QSAR, ECOSAR Program v1.11 was used to predict the toxicity. The QSAR is acceptable with restrictions. The LC50 (48 hours) for daphnia is estimated to be 307.5 mg/L in fresh water
