Description of key information
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 103 mg/L
Additional information
A concentration series of test substance from 7.4 to 103 mg/L loading of hydrogenated terphenyl in water (after 6 days stirring at room temperature) was used to prepare a series of WAFs. All WAFs showed the same final dissolved concentration of 25+/-5 µg/L. The WAFs of hydrogenated terphenyl have no adverse effects on the respiration rate of activated sludge: respiration rates in the test conditions were all comparable to the control.
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.
