Description of key information
3 hour EC50 >1000 mg/L in activated sludge (OECD 209)
Key value for chemical safety assessment
- EC50 for microorganisms:
- 1 000 mg/L
Additional information
The toxicity of MTDID 44430 to activated sludge was assessed according to the OECD 209 guideline in a definitive test conducted at 10, 100, 300, and 1000 mg/L. The validity criteria were met based on an acceptable level of oxygen uptake in control samples, acceptable variation among control replicates and a typical level of inhibition with the positive control. The 3-hour EC50 (respiration) of MTDID 44430 to activated sludge is >1000 mg/L, as no inhibition was was observed. The study followed an international standard method and is GLP compliant. Therefore, the study is deemed reliable without restrictions.
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.
