Key value for chemical safety assessment
Additional information
The effect of the test substance on oxygen consumption of activated sludge was performed according to OECD guideline 209. The test substance 2-[(2-methoxy-5-nitrophenyl)diazenyl]-N-(2-methoxyphenyl)-3-oxobutanamide was tested at nominal concentrations of 62.5, 125.0, 250.0, 500.0, and 1000 mg/L in a static setting. No inhibitory effect on the respiration rate of activated sludge after an incubation period of three hours was determined. The NOEC was > 1000 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).
