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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
