Additional information
According to Annex X, section 9.5.1., column 2, to REACH long-term toxicity tests for sediment organisms shall be proposed if the result of the chemical safety assessment indicates the need to investigate further the effects of the substance. According to “Guidance on information requirements and chemical safety assessment Chapter R.7b: Endpoint specific guidance”, Section 7.8.14 Integrated Testing Strategy for toxicity to sediment (ECHA, 2017), the main property of a substance that triggers the assessment for the sediment compartment is the potential to adsorb or bind onto sediment. A log Kow of 3 should be used as trigger value for a sediment assessment. The substance Sulfuric acid, mono-C12-14 (even numbered)-alkyl esters, ammonium salts exhibits low potential for adsorption to sediment (log Kow = 0.8 at 22°C). Additionally this is confirmed by the adsorption coefficient (experimental value) of log Koc 2.5 – 3.19.
Moreover, the risk for sediment organisms was calculated based on the equilibrium partitioning method (EPM). The PEC/PNEC ratios for the sediment compartment are below one. Taking all the available information mentioned above into account long-term sediment tests with benthic species are not required.
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.
