Description of key information
Additional information
Vanadylhydrogenphosphate-hemihydrate (CAS no. 93280-40-1) is inorganic; according to REACH Guidance Document R.7b (v4.0; ECHA 2017), “biodegradability testing of inorganic substances is not worth doing.” In addition, a study on ready biodegradability does not need to be conducted for inorganic substances according to Annex VII, Section 9.2.1.1, Column 2 of Regulation (EC) 1907/2006.As biodegradation testing is not relevant for metals and metal compounds like vanadylhydrogenphosphate-hemihydrate (CAS no. 93280-40-1), further testing according to Annex IX, Section 9.2.1, Column 2 of Regulation (EC) 1907/2006 is not performed. The substance is considered as not (bio)degradable. Therefore, the chemical assessment of divanadium pentaoxide 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.
