Description of key information
EC50 > 730 mg/L (corresponding to 1000 mg/L test material containing 73% submission substance);
Key value for chemical safety assessment
Additional information
In an activated sludge respiration inhibition test according to OECD 209 and performed compliant to GLP (reliability categroy 1), toxicity of the submission substance towards sewage treatment plant bacteria was assessed. The inoculum was derived from a municipal sewage treatment plant and non-adapted. As the test item is poorly soluble in water, the test item concentrations were reached by directly adding the test substance to the test medium.
Derived effect values:
EC50 > 730 mg/L (corresponding to 1000 mg/L test material containing 73% submission substance);
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).
