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

EC10, LC10 or NOEC for freshwater 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.
