Additional information
In the assessment of environmental fate and toxicity of iron vanadium tetraoxide, read-across to the assessment entities „vanadium ions“ and „iron ions“ is applied since the ions of iron vanadium tetraoxide determine the environmental fate and toxicity of iron vanadium tetraoxide. Since vanadium and iron ions behave differently in the environment, a separate assessment of the environmental fate and toxicity of each assessment entity is performed. Please refer to the data as submitted for each individual assessment entity. For a documentation and justification of that approach, please refer to the separate document attached to section 13, namely Read Across Assessment Report for iron vanadium tetraoxide.
Conclusion on classification
Iron vanadium tetraoxide is poorly soluble. The results from a standard water solubility test according to OECD 105 indicate that at a loading of 25 mg/L, the dissolution of iron vanadium tetraoxide after 37 days results in a vanadium concentrations of 145.5 microg V/L whereas iron concentrations remained ≤ 1.13 microg/L. The acute and chronic ecotoxicity reference values of 0.693 and 0.120 mg V/L are based on dissolved elemental vanadium concentrations. Thus, the dissolved vanadium concentration of iron vanadium tetraoxide after 37 days in water is below the acute but not the chronic reference values for dissolved elemental vanadium. There are not any indications that the assessment entity “iron ions” (i.e. diiron trioxide) would be classified as environmental hazard under Regulation (EC) No 1272/2008.
Iron vanadium tetraoxide does not meet based on i) the acute aquatic ecotoxicity value of 0.693 mg V/L; ii) the maximum vanadium content of iron vanadium tetraoxide of 30 %, and iii) the resulting acute ecotoxicity reference value of 2.31 mg/L iron vanadium tetraoxide classification criteria of acute (short-term) aquatic hazard Category 1 of Regulation (EC) No 1272/2008.
Based on the chronic aquatic ecotoxicity value of 0.120 mg V/L; ii) the maximum vanadium content of iron vanadium tetraoxide of 30 %, and iii) the resulting chronic ecotoxicity reference value for iron vanadium tetraoxide of 0.400 mg/L, iron vanadium tetraoxide meets in accordance with Table 4.1.0 (b) (i) of Regulation (EC) No 1272/2008 criteria of Category 2 for long-term aquatic hazard.
