Description of key information

EC50: >191 ng/l; NOEC 191 ng/l; LOEC >191 ng/l (highest concentrations tested) (mean measured concentrations): effects of the test substance on survival, growth and reproduction of Daphnia magna.

Key value for chemical safety assessment

191 ng/L

Additional information

A 21 day EC50 value of >191 ng/l, a NOEC value of 191 ng/l and a LOEC value of >191 ng/l (highest concentrations tested), based on mean measured concentrations, have been determined for the effects of the test substance on survival, growth and reproduction of Daphnia magna, in accordance with OECD Guideline 211.

The test solution preparation method and test system design indicate that the test organisms were predominantly exposed to the parent substance.
