Description of key information

Experimental aquatic toxicity studies of reliabilities 1 or 2 (Klimisch rating), based on international guidelines, are available on the registered substance for aquatic invertebrates and algae. According to these results, the aquatic invertebrates Daphnia magna was considered to the most sensitive species. The 48h-EC50 value based on mobility on D. magna was determined to be 1.8 mg/L (95% CL: 1.0 - 3.3 mg/L) and the 72h-ErC50 value based on growth rate on Pseudokirchneriella subcapitata was determined to be greater than the highest tested concentration, 2.67 mg/L. However, a 72h-ErC10 value based on growth rate on P. subcapitata was determined at 1.54 mg/L(95% CL: 1.02 - 2.28 mg/L).
