Description of key information

Toxicity of the test item to activated sludge in a respiration inhibition test resulted in an EC50 value of greater than 1000 mg/L

Key value for chemical safety assessment

EC50 for microorganisms:
1 000 mg/L

Additional information

EC50 value clearly higher than the limit of water solubility of the test item under the present test conditions, or higher than the nominal concentration of 1000 mg/L. The 3-hour NOEC was at the nominal concentration of 1000 mg/L and thus greater than the limit of water solubility determined in this test.
