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 and in an experimental chronic Daphnia study ( NOACK, 2021) the LOEC value for aquatic invertebrates, based on reproduction, was determined to be > 0.937 mg/L. The value predited by calculation method (KREATiS, 2021)  21d - EL10 = 0.2 mg/L supports this value.


In addition, reliable calculation method result is available to assess chronic toxicity to fish 32d- EL10 value predicted was 0.4 mg/L.


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.
