Description of key information
EC50 (3h) > 762 mg/L (corresponding to 1000 mg/L test material containing 76.2% submission substance)
Key value for chemical safety assessment
Additional information
In an activated sludge respiration inhibition test according to OECD 209 performed without GLP but compliant to principles of good laboratory practice (reliability category 2), toxicity towards sewage treatment plant bacteria was assessed. The inoculum was derived from a municipal sewage treatment plant. As the test item is poorly soluble in water, the limit concentration of 1000 mg/L was reached by directly adding the test substance to the test medium. No significant respiration inhibition could be observed. Derived effect values:
EC50 (3h) > 762 mg/L (corresponding to 1000 mg/L test material containing 76.2% 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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
