Description of key information
Key value for chemical safety assessment
Additional information
Testing for sediment toxicity is not considered necessary because:
PNECsediment has been calculated from PNECfreshwater on the basis of the equilibrium partitioning method; the risk characterisation ratios (RCR) based on PNECsediment derived from this method are <1.In accordance with Annex XI, section 2, the long-term toxicity effects studies to sediment dwelling organisms (required in Section 9.5.1) do not need to be conducted as the study is technically not possible. This is due to the very short sediment half-life once desorbed (see CSR for further details), preventing maintenance of exposure concentrations.
PNECsediment has been calculated from PNECfreshwater on the basis of the equilibrium partitioning method; the risk characterisation ratios (RCR) based on PNECsediment derived from this method are <1.
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).
