Additional information
The inhibitory effect of the Acid Blue 280 on aerobic waste-water bacteria was investigated following the OECD guideline 209. It should be considered that the test sample has a low content of Acid Blue 280, thus test results should be taken with caution.
The method determines the respiration rate (oxygen consumption) of an aerobic actlvated sludge fed with an excess but standard amount of biodegradable food as compared to the respiration rate obtained in an activated sludge run under identical conditions but containing the test chemical. The nominal test concentrations applied were 10 and 100 mg/l. Under the tested condltions, the respiration rate of the sludge was no inhibited at 3 hours (0.8 %) at the highest concentraton of 100 mg/l.
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.
