Description of key information
Performance of a test for bioaccumulation in aquatic species was waived. Substances of the Persulfate Category are inorganic salts sharing the same anionic persulfate moiety. Persulfates are very soluble in water and are not expected to bioaccumulate in soil or aqueous solutions. They will decompose into organic sulfate or bisulfate.
Key value for chemical safety assessment
Additional information
In accordance with Column 2 of REACH Annex IX, bioaccumulation in aquatic organisms, information requirement 9.3.2, can be waived if the substance has a low potential for bioaccumulation and direct and indirect exposure to the aquatic compartment is unlikely. Substances of the Persulfate Category are inorganic salts sharing the same anionic persulfate moiety. Persulfates are very soluble in water and are not expected to bioaccumulate in soil or aqueous solutions. They will decompose into organic sulfate or bisulfate. Experimental determination of a log Pow was waived, instead a default log Pow of -1 was assumed for risk assessment (EUSES v 2.1 default). Based on the low potential for bioaccumulation, experimental determination of the bioaccumulation factor (BCF) was waived.
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.
