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)
