Description of key information
The inhibition of the degradation potential of activated sludge is not anticipated when is introduced in appropriately low concentrations.
Key value for chemical safety assessment
Additional information
The assessment of the toxicity to microorganisms is derived on the available data from an inhibition control of a DOC-die-away test conducted according to EU method C.4-A (see also Section 5.2).
The results of the key study in Section 5.2 indicate that
a) The substance is not readily biodegradable (according to OECD criteria),
b) inhibitory effects of the substance to sewage sludge bacteria were not observed at the tested concentration 78 mg/L, and
c) the inhibition of the degradation potential of activated sludge is not anticipated when the substance is introduced in appropriately low concentrations.
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.
