Description of key information
Daphnia Reproduction Test (21 days) was performed in order to examine the long-term aquatic toxicity of invertebrates to the test substance. NOEC and LOEC values of 55.6 mg/L and 100 mg/L were obtained respectively.
Key value for chemical safety assessment
Fresh water invertebrates

- 55.6 mg/L
Additional information
Daphnia reproduction test (21 days) was assessed similarly to OECD 211 guideline with the test substance in the following concentrations: 55.6, 100 mg/L. The test substance tends to split immediately to two components in aqueous solution. Its half-life is about 1 hour, and it almost fully decomposes in 5 to 6 hours. Therefore, concentration of the test substance in a test solution was not measured. Thus, the test result was calculated in accordance with a target concentration. Under the test conditions the NOEC (reproduction) and the LOEC (reproduction) values obtained were 55.6 mg/L and 100 mg/L, respectively.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
