Description of key information
The amounts of Al (pH 7) / Mg / V after five days was more than 90% of the amount at the start of the test, therefore whole Aluminium magnesium vanadium was considered to be stable.
In accordance with column 2 of Annex VII, 9.2.1.1 of Regulation (EC) No 1907/2006, testing for biodegradation is not required as the substance is inorganic.
Bioaccumulation is of no concern for the assessed substance.
No adsorption/desorption studies are available for Aluminium Magnesium Vanadium oxide. However, the adsorption/desorption behaviour of the different metals in the environment is well known. The undissolved fraction of the substance will deposit in soil or sediment, and the dissolved metals will undergo speciation in function of the environmental conditions.
Additional information
Due to its low solubility in water, Aluminium Magnesium Vanadium oxide will mainly remain undissolved under environmental conditions and will deposit in soil or sediment. A minor fraction may dissolve into the aqueous phase. In this case each metal will undergo speciation in function of the environmental conditions. The speciation of metals in the environment depends on several parameters, such as pH, redox potential, DOC and the presence of anions. Free aluminium ions are likely to react with water to form aluminium hydroxides. Magnesium is naturally present in the environment as free ions as well as in bound form. The adsorption potential of vanadium seems to vary strongly depending on the type of soil. Kd values from 1.70 to 360.91 L/kg have been reported. All of the three metals are naturally present in the environment. Mean concentrations for aluminium, magnesium and vanadium in water of 0.076 mg/L, 11.5 mg/L and 0.008 mg/L, respectively, have been reported by Salminen et al. (2005).
Biodegradation is not relevant, since the substance is inorganic. The dissolved metal ions may participate in hydrolysis reactions, thereby forming a number of monomeric and polymeric hydroxides and this process is highly dependent on pH. However, the metals will persist in the environment irrespective of whatever chemical species are formed as a result of hydrolysis.
