Description of key information

Two key studies and one supporting study shows that the nominal EC50 value for freshwater invertebrates is above 100 mg ai /L. In one key study and in the supporting study a NOEC of 100 mg ai /L is reported. In the two highest concentrations (140 and 200 mg/L) in the supporting study effects have occurred. In both concentrations the pH was below 6 (140 mg/L = 5.5 and 200 mg/L =3.6). Therefore it can not be excluded, that the effects based on the low pH value only. The values will not be used for chemical safety assessment.
