Description of key information
Due to the low aquatic toxicity, the high water solubility and low adsorption potential, hazards to sediment dwelling organisms are not expected.
Key value for chemical safety assessment
Additional information
No data are available for the toxicity assessment of the test substance to sediment organisms. However, tert-butanol, the organic hydrolysis product of sodium 2 -methylpropan-2 -olate, has a low potential for adsorption to sediment particles (log Koc of 0.32) and it has no bioaccumulative properties (log Kow clearly below 3). Additionally, the lack of any harmful effects in aquatic tests on all three trophic levels at concentrations below or equal 100 mg/L indicate a low hazardous potential of the test substance towards sediment organisms. Therefore, the risk to sediment dwelling organisms is considered negligible and no tests on sediment 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.
