Key value for chemical safety assessment
- EC50 for freshwater algae:
- 100 mg/L
- EC10 or NOEC for freshwater algae:
- 77 mg/L
Additional information
The test substance was tested for growth inhibition on algae.
The full test was performed in range of test substance nominal concentrations 21 - 100 mg·L-1.
The nominal concentrations of the test substance were used for all evaluations and results.
Test results:
72 hour - EbC50 = 87 mg·L-1 (95% confidence limit: 78.11 – 95.92 mg·L-1) (nominal concentration)
72 hour - ErC50 > 100 mg·L-1 (nominal concentration)
72 hour - NOECb = 77 mg·L-1 (nominal concentration)
72 hour - NOECr = 77 mg·L-1 (nominal concentration)
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
