Description of key information
No data on sediment toxicity are available.
2 -methylpropan-1 -ol has no tendency to adsorb to particulate matter and is readily biodegradable. Therefore, an assessment on sediment toxicity is not required.
Key value for chemical safety assessment
Additional information
In Annex X of the Regulation (EC) No 1907/2006 REACH concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), it is suggested, that "long-term toxicity testing shall be proposed by the registrant if the results of the chemical safety assessment indicates the need to investigate further the effects of the substance and/or relevant degradation products on sediment organisms. The choice of the appropriate test(s) depends on the results of the chemical safety assessment."
2 -methylpropan-1 -ol has a low potential for adsorption or bioaccumulation, exhibits a very high solubility in water and is readiliy biodegradable. In addition, results from the aquatic studies indicate no harmful effects. Therefore exposure of sediment organisms is unlikely and testing towards sediment dwelling organisms not necessary. Furthermore, the equilibrium partitioning method can be used for assessing the hazard of sediment organisms.
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.
