The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Three acute experimental studies and two QSAR predictions are available to assess the aquatic toxicity of the registered substance.

The two experimental studies, performed on aquatic invertebrates Daphnia magna and the algae Desmodesmus subspicatus respectively, were not considered reliable due to major methodological deficiencies and/or insufficient information provided on the methodology used. Therefore, QSAR predictions for these endpoints were performed using iSafeRat® High-Accuracy-Quantitative Structure-Activity Relationship (KREATIS, 2019). Toxic effects were predicted on aquatic invertebrates and algae in acute conditions. For daphnids, the 48h-EC50 value was predicted at 0.92 mg/L. For algae, the 72h-ErC50 value was predicted at 2.5 mg/L.

Finally, an experimental study performed on fish Danio rerio was considered reliable (with restrictions). The 96h-LC50 value was determined at 1.9 mg/L, based on initial measured concentrations.
