Description of key information
A study is available in which the effect of MgO2 as a bio-stimulant agent was examined by application of the substance to a microcosm simulating the sediment of aquaculture farms with a high load of organic matter. The dominance of sulphate-reducing bacteria (SBR) was used as one of the parameters to monitor sediment conditions. Other parameters assessed were redox potential and amount of organic carbon and nitrogen.
These experimental findings demonstrate that magnesium peroxide can function as an oxygen-releasing compound (ORC) and as such can improve the quality of organically polluted sediment by reducing the abundance of sulphate-reducing bacteria and the levels of sulfides.
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.
