Description of key information

Valid acute studies based on international guidelines are available for the three aquatic trophic levels (algae, aquatic invertebrates and fish). Among all data available, a toxic effect was observed for the three aquatic trophic levels. The fish Danio rerio is the most sensitive species with a 96h-LC50 value at 52.0 mg/L based on analytically confirmed nominal concentration. For the algae Pseudokirchneriella subcapitata, the 72h-ErC50 and 72h-NOEC values based on growth rate were determined to be greater than the highest tested concentration 67.9 mg/L and 16.6 mg/L, respectively, based on geometric mean measured concentrations. For the aquatic invertebrates Daphnia magna, the 48h-EC50 value was determined to be 108 mg/L based on analytically confirmed nominal concentration. In addition, the registered substance was not toxic to activated sludge of a municipal sewage treatment plan up to the nominal concentration of 100 mg/L.

Additional information

Although not requested under REACH Annex VII, the vertebrate acute fish study was performed to comply with worldwide regulations.
