Description of key information
The inhibitory effect of DNBP on the respiration of activated sludge was examined in an experiment conducted in accordance with OECD 209, EU method C.11 and US EPA OPPTS 850.6800 guidelines.
The effect of the test item on the respiration of activated sewage sludge micro-organisms gave a 3-Hour EC50 of 130 mg/l, 95% confidence limits 100 - 170 mg/l. The No Observed Effect Concentration (NOEC) after 3 hours exposure was 22 mg/l.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 130 mg/L
- EC10 or NOEC for microorganisms:
- 22 mg/L
Additional information
A reliability rating of 1 was assigned to the key study, according to the criteria of Klimisch, 1997 as the study was conducted in accordance with recognised guidelines and GLP.
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.
