Additional information
The respiration inhibition of the test material CA3105A (93.9% purity) was determined after 3 hour incubation according OECD 209 in predominantly domestic sludge. The test item had no adverse effect on the respiration of activated sludge at concentrations up to 100 mg/L which was the highest tested concentration. NOEC = 100 mg/L EC10 >= 100 mg/L EC50 >= 100 mg/L. The test with the reference substance was valid. Therefore, the results of this study are considered to be acceptable for the assessment of the 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.
