Description of key information
In 72-h growth inhibition study Desmodesmus subspicatus were exposed to the test item at nominal concentrations of 0.1, 0.32, 1.0, 3.2 and 10 mg/L. Test concentrations were achieved by dilution of water accommodated fractions. The EL50 and EL10 based on growth rate were determined to be 3.26 mg/L and 0.471 mg/L, respectively. The EL50 and EL10 based on biomass was 0.724 mg/L and 0.519 mg/L, respectively. The substance is acutely toxic for aquatic plants. The substance is chronic harmful for aquatic plants.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 3.26 mg/L
- EC10 or NOEC for freshwater algae:
- 0.471 mg/L
