Description of key information
Determination of the chronic toxicity to Daphnia magna with FAT 40870/A TE (Reproduction test on daphnia magna).
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 25
Additional information
The chronic toxicity of the test item was assessed in a Daphnia magna reproduction test.
Based on the results of acute toxicity range finding test and an initial test, Daphnia magna were exposed (10 replicates of a single daphnid per group) to solutions of the test item at nominal concentrations of 3.125, 6.25, 12.5, 25 and 50 mg/L in Elendt M7 media for a period of 21 days.
Exposure of Daphnia magna to the test item gave the following results based on the nominal test concentrations:
