Aquatic toxicity

The available reliable ecotoxicity results selected for the effect of the substance on aquatic organisms are all based on a supersaturated suspension with a loading rate of 100 mg/L of the test substance (OECD Series, No. 23 (2000)).

Daphnia magna

The results indicate that the substance does not effect the mobility of the freshwater invertebrate Daphnia magna after 48-hours of exposure

up to the analytically measured concentration of 79 µg/L which corresponds to the solubility limit of the test item in test water at a loading rate of 100 mg/L.

 

Algae

The results indicate that the respective 72-h EC10 and 72-h EC50 for the inhibition of growth rate of the freshwater green algae Pseudokirchneriella subcapitata are above the highest nominal loading rate of 100 mg/L test substance, corresponding to a geometric mean measured concentration of 119 µg/L test substance.
