- 15.4 mg/L
Additional information
The toxicity of the test item to activated sewage sludge was taken from the toxicity control of a GLP-compliant ready biodegradability CO2evolution test following OECD guideline 301B (Harlan 2013). In the toxicity control the biodegradation rate of a reference substance known to be readily biodegradable is followed in the presence of the test item. The test item did not exhibit any inhibitory effects on the biodegradation rate of the reference substance, indicating that it was not toxic to the microorganisms at the concentration tested.
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.
