Description of key information
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 "in the absence of toxicity data for soil organisms, the equilibrium partitioning method may be applied to assess the hazard to soil organisms. The choice of the appropriate tests depends on the outcome of the chemical safety assessment. In particular for substances that have a high potential to adsorb to soil or that are very persistent, the registrant shall consider long-term toxicity testing instead of short-term.These studies do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely."
The available experimental data for Propan-1 -ol are not appropriate for a derivation of PNECsoil.
The substance however, exhibits low potential for adsorption, is not bioaccumulative and readily biodegradable. Furthermore, results of aquatic tests revealed no harmful effects of Propan-1 -ol, and by thereby suggesting little hazardous potential towards soil organisms. Therefore, the equilibrium partitioning method has been used to assess the hazard potential of Propan-1 -ol for soil organisms.
For deriving a PNECsoil the guidance for the implementation of REACH, Chapter 10 states: “when only one test result with soil organisms is available the risk assessment is performed both on the basis of this result using assessment factors and on the basis of the equilibrium partition method (EPM). From both PECsoil/PNECsoil ratios the highest one is chosen for the risk characterisation.” Taking the EC50 concentration of Reynolds (1977) into account a PNECsoil of 2.25 mg/kg soil d.w. (assessment factor 1000) can be derived. In contrast using the equilibrium partitioning method a PNECsoil of 1.49 mg/kg soil d.w. can be derived. Since the results are similar for both assessments, the risk assessment will be performed using the derivation of EPM.
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.
