Biodegradation in water and sediment: simulation tests

Description of key information
Studies on the biodegradability in water and sediment do not need to be conducted because the substance is inorganic.
Key value for chemical safety assessment
Additional information
According to Annex IX, Section 9.2, Column 2 of Regulation (EC) 1907/2006, "Further biotic degradation testing shall be proposed by the registrant if the chemical safety assessment according to Annex I indicates the need to investigate further the degradation of the substance and its degradation products. The choice of the appropriate test(s) depends on the results of the chemical safety assessment." Degradation/biodegradation testing is not relevant for metals and metal compounds, like vanadylhydrogenphosphate-hemihydrate (CAS no. 93280-40-1), which are considered as not (bio)degradable. Therefore, the chemical assessment of vanadylhydrogenphosphate-hemihydrate (CAS no. 93280-40-1) is based on the total initial vanadium concentration, which can be considered as a worst-case assumption.
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.
