Additional information
According to the standard requirements set in Regulation (EC) No. 1907/2006, Annexes VII and VIII, information regarding the effects of the substance to sediment organisms does not need to be presented at this tonnage band (10-100 t/y). Moreover, the environmental exposure assessment according to Annex XI, section 3 performed for this substance shows that the Risk Characterization Ratio (i.e. PEC/PNEC ratio) in the sediment compartment is < 1 and therefore, under the current exposure conditions, UM-235 does not pose a risk to 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.
