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, 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.
