Description of key information
The inhibition of the degradation activity of activated sludge is not anticipated when the substance is introduced in appropriate low concentrations.
Key value for chemical safety assessment
Additional information
The data on toxicity to microorganisms are based on results obtained for 3,7-dimethyl-3-ol, since no data for 3,7-dimethyl-1-ol are available. The respiration rate of microorganisms in presence of 3,7-dimethyl-3-ol was tested by a test conducted in compliance with German standard, DIN 38412, part 27 focused on the respiration of the species Pseudomonas putida. By measuring the oxygen consumption of P. putida for 30 minutes an EC50 of 1000 mg/l was determined (BASF AG, 1989).
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.
