Key value for chemical safety assessment

EC50 for microorganisms:
100 mg/L

Additional information

Bacteria toxicity was tested following the procedures outlined into the OECD guideline 209. Test substance was evaluated at the concentrations of 10, 32 and 100 mg/l and the EC50 at 3 hours was set higher than 100 mg/l. The test was conducted according to internationally accepted testing guidelines, but only the summary is actually available.

Nevertheless, the result is confirmed by other test results, for which complete test report are not available.

In conclusion, the substance does not inhibit the activity of activated sludge in concentrations higher than or equal to 100 mg/l.
