Description of key information
Waiving of study:
The substance has no high potential to adsorb to soil and is not very persistent. Hypochlorite dissipates rapidly in contact with soil with a DT50 of < 1 minutes. The environmental risk assessment for the terrestrial compartment was performed on the basis of a calculated PNECsoil of 0.03 µg/kg, derived from the PNECaquatic using the equilibrium partitioning method. The resulting PEC/PNECsoil values are < 1.
In accordance with column 2 of REACH Annex IX, Effects on soil micro-organisms (required in section 9.4.2) do not need to be conducted as the equilibrium partitioning method was applied to assess the hazard to soil organisms.
Key value for chemical safety assessment
Additional information
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.
