Description of key information

EC50 of the test substance was greater than 100 mg/L.

Key value for chemical safety assessment

Additional information

In Preliminary test, the test substance has been tested in 100 mg/L and the result of test was 8.59% growth inhibition to Pseudokirchneriella subcapitata. The value was less than 75%, so that the highest does of test substance was 100 mg/L. The pH values in 100, 50, 25, 12.5 and 6.25 mg/L were less than ± 1.5. The specific growth rate of control group in this test came up to quality requirements, so that the data in this test were valid. According to OECD Guideline 201 (Alga, Growth Inhibition Test), EC50of the test substance was greater than 100 mg/L.
