Description of key information

An OECD 211 GLP test has been conducted with NOEC >= 20mg/L

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater invertebrates:
20 mg/L

Additional information

The purpose of this study was to assess the toxicity of the test substance dissolved in fresh water, on the reproductive efficacy of Daphnia magna STRAUS - clone 5, in a semi-static test complying with the OECD Guideline No. 211. The test criterion of toxicity used was reproductive capacity expressed as the number of neonates per daphnid during the study. The nominal concentrations used in the study were as follows: 0, 1.0, 2.2, 4.5, 9.5 and 20.0 mg/L All concentrations given refer to the technical product as supplied. The results of the chemical analyses show that the concentrations in the test solutions freshly prepared were all close to nominal test concentrations. Some of the used solutions were higher than nominal, this is not taken into account and nominal test substance concentrations were used to calculate the effects. The NOEC (reproduction, parent length and weight) was > 20 mg/L
