Description of key information
Waiver: indirect and direct exposure to terrestrial organisms is unlikely.
Key value for chemical safety assessment
Additional information
Measured toxicity data are not available for terrestrial organisms for o-tert-butylphenol.
In Annex X of Regulation (EC) No 1907/2006, it is laid down that long-term toxicity to terrestrial organisms shall be proposed by the registrant if the chemical safety assessment indicates the need to investigate further the effects of the substance and/or relevant degradation products on terrestrial organisms. Column 2 of Annex X states that studies do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely.
The test substance is not supposed to be applied directly to soil. Reliable biodegradation study results indicatethatthe substance is considered inherently biodegradable. Use of the substance does not include direct exposure to soil. It can be assumed that o-tert-butylphenol will be biodegraded within the STP process and as a consequence a transfer to the soil compartment via sewage sludge is not expected. Any release to wastewater treatment plant or soil from residual o-tert-butylphenol in resin is negligible. Therefore, no tests on terrestrial organisms are provided.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.
