Description of key information
Determination of the acute toxicity of TK 30250 in Daphnia magna (Acute 48-hours immobilization test).
Key value for chemical safety assessment
Additional information
The study was performed to assess the acute toxicity of the test item to Daphnia magna.
Chemical analysis of the test preparations at 0 and 48 hours showed measured test concentrations of less than the limit of quantification (LOQ) of the analytical method employed were obtained which was determined to be 0.00565 mg/L. This does not infer that no test item was in solution, just that any dissolved test item was at a concentration of less than the LOQ.
Exposure of Daphnia magna to the test item gave EC50values based on the nominal test concentrations of greater than 100% v/v saturated solution. The No Observed Effect Concentration was 100% v/v saturated solution.
This study showed that there were no toxic effects at saturation.
