Description of key information
Testing on long-term toxicity to sediment organisms has been judged to be not necessary in accordance with column 2 of REACH Annex X and also in accordance with section 3 of REACH Annex XI. In accordance with column 2 of REACH Annex X 9.5.1,the Long-term toxicity to sediment organisms is not proposed because the results of the chemical safety assessment do not indicate any need to investigate further the effects of the substance and/or relevant degradation products on sediment organisms.
Key value for chemical safety assessment
Additional information
Due to the lack of ecotoxicological data for sediment organisms an estimation of the PNEC for sediment was performed using the equilibrium partitioning method (EPM) as recommended in the Guidance on information requirements and chemical safety assessment Chapter R.10 (ECHA, 2008).
On this basis the chemical safety assessment demonstrates that for all uses, the exposure levels estimated for the sediment compartment do not exceed the appropriate PNEC values, the resulting RCR values are all below 0.1 providing a high margin of safety for sediment dwelling 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.
