The test substance is not considered to be toxic to microorganisms under the conditions of the test. - Executive summary:
The acute toxicity of the test substance to microorganisms has been determined in a test according to Directive 87/302 No. 133/118. The IC50 (0.5h) was > 100 mg/L. This result shows that at a concentration in excess of the water solubility level of the test material, the test material does not have an effect on the respiration rate of activated sewage sludge.
