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.

Aquatic invertebrate, Daphnia magna, are the most sensitive species with a 48h-EC50 value at 1.1 mg/L based on time-weighted mean concentrations

For the algae Pseudokirchneriella subcapitata, the 72h-ErC50 and 72h-ErC10 values based on growth rate were determined to be 2.6 and 1.5 mg/L, respectively, based on time-weighted mean concentrations.

For the fish, Danio rerio, the 96h-LC50 value was determined to be 4.07 mg/L based on the geometric mean of the measured concentrations.

For micro-organisms, the effect of the test item on the respiration of activated sewage sludge micro-organisms gave a 3-Hour EC50 value of greater than 100 mg/L.

Additional information

Although not requested under REACH Annex VII, the vertebrate acute fish and ASRIT studies were performed to comply with worldwide regulations.
