Description of key information

The nominal test item concentrations tested were 2.2, 4.6, 10, 22, 46 and 100 mg/L. Additionally, a control was tested in parallel.
The 48-hour EC100 is > 100 mg/L. The 48-hour NOEC is about 22 mg/L.

Key value for chemical safety assessment

Additional information

The acute toxicity of the test item to Daphnia magna was determined in a 48-hour static test according to the EU Commission Directive 92/69/EEC, Part C.2 (1992), and the OECD Guideline for Testing of Chemicals, No. 202, Part I (1984).

 

The nominal test item concentrations tested were 2.2, 4.6, 10, 22, 46 and 100 mg/L. Additionally, a control was tested in parallel.

 

The analytically determined test item concentrations in the analyzed test media from the start and the end of the test varied in the range from 80 to 92% of the nominal values. Consequently, the test item was stable during the test period of 48 hours under the conditions of the test, and the reported biological results are based on the nominal concentrations of the test item.

 

The 48-hour EC100 is > 100 mg/L. The 48-hour NOEC is about 22 mg/L.
