Description of key information

No toxic effects were observed up to the attainable limit of solubility of the substance in experimental acute studies for the three trophic levels (fish, aquatic invertebrates and algae).

Regarding long-term exposure, no toxic effect was observed in the algae experimental study at the maximum attainable mean test concentration but EC10 values were determined by High Accuracy QSAR predictions (iSafeRat QSAR model) at 0.088 mg/L for aquatic invertebrates and 0.10 mg/L for fish.

Based on the respiration inhibition test, the substance had no inhibitory effect on the respiration rate of activated sludge, after the incubation period of 3 hours at the maximum test item concentration tested of 100 mg/L.

A testing proposal is included in the dossier to conduct an experimental Daphnia magna reproduction test, according to OECD Guideline 211, on the registered substance. The test on aquatic invertebrates is proposed, since according to the outcome of iSafeRat QSAR model, Daphnia magna is the most sensitive species in chronic exposure. An experimentally- determined EC10 value would allow to conclude appropriately on the environmental classification of the registered substance. After acceptance of the submitted testing proposal for a Daphnia magna reproduction test, by ECHA, and when the new experimental study report is made available, the dossier and the final environmental classification will be updated.
