TEST ATMOSPHERE
- Brief description of analytical method used: the atmosphere generated was measured gravimetrically at regular intervals (approx. 50 min) during exposure by pulling a volume of 5 L of test atmosphere from the exposure chamber through glass fibre filters (Fiberfilm T60A20, Pallflex Product Corp.). The duration of each sampling was 5 minutes. Sampling was performed 5 times: shortly after chamber equilibration and then at regular intervals during the exposure. Samples were collected from a vacant animal exposure port (animals' breathing zone). The actual sampling schedule employed was designed in order to obtain adequate quantities of test item. The achieved average concentration was calculated by combination of the gravimetric results and the recorded real-time data provided by the Aerosol Light Scattering Photometer integrated in the monitoring system of the exposure apparatus. The photometer was calibrated during the technical trials and the recorded data were corrected following the treatment according to the results of gravimetric concentration measurements. The test atmosphere concentration measurements were conducted also during sighting exposure.

Additional information
Oral
An acute oral toxicity study with aluminium magnesium vanadium oxide according to the acute toxic class method (OECD guideline 423) and GLP was performed in female RccHan: WIST rats (2012). Two groups, each consisting of 3 animals, were treated with the test substance diluted in olive oil as vehicle by single oral gavage administration at a limit dose of 2000 mg/kg bw in a stepwise procedure. No mortality and no clinical signs were observed during the study period. All 6 animals showed the expected gain in body weight after treatment. The macroscopic examination revealed a thinning of the forestomach in 3 of 6 animals. Based on the experimental results, the LD50 of aluminium magnesium vanadium oxide was greater than 2000 mg/kg bw. According to the criteria of OECD guideline 423, the LD50 cut-off of aluminium magnesium vanadium oxide may be considered to be greater than 5000 mg/kg bw.
Inhalation
The acute inhalation toxicity of aluminium magnesium vanadium oxide was studied in Wistar CRL (WI) BR rats according to OECD guideline 403 and in compliance with GLP (2012). A preliminary sighting study was performed in 1 male and 1 female animal at a target concentration of 5 mg/L of the dust aerosol for a period of 4 h using a nose only exposure system. Since no mortality occurred in this study, 5 male and 5 female animals of the main study were exposed for 4 h to the same target concentration, corresponding to an analytical atmosphere concentration of the dust aerosol of 4.852 mg/L (4852 mg/m³). No mortality and no clinical signs of toxicity were observed in any of the animals during the 14-day observation period. A slight loss in body weights was observed in both genders at the day of inhalation exposure, but was compensated from Day 3 of the observation period. At necropsy, no abnormalities were noted in the animals. Based on these results, the LC50 value for male rats was assumed to be greater than 5 mg/L (5000 mg/m³), corresponding to an analytical concentration of 4.852 mg/L (4852 mg/m³).
Dermal
The acute dermal toxicity of aluminium magnesium vanadium oxide was investigated in a study according to OECD guideline 402 and compliant with GLP (2012). In this limit test, 5 male and 5 female Sprague Dawley rats were exposed to the test substance at a dose of 2000 mg/kg bw. The test substance was applied at a concentration of 0.2 g/mL in liquid paraffin onto the clipped dorsal skin of the test animals for 24 h under semiocclusive conditions. After removal of the test substance, animals were observed for a period of 14 days. A slight yellow coloration was noted on the treatment site 24 and 48 h after test substance application in all males. No mortalities and no signs of systemic toxicity were observed. No effect on body weight was noted during the study. At necropsy, no macroscopic findings were recorded. Based on these results, the dermal LD50 value for male and female rats was greater than 2000 mg/kg bw.
Justification for classification or non-classification
The available data on the acute toxicity of aluminium magnesium vanadium oxide do not meet the criteria for classification according to Regulation (EC) 1272/2008 (CLP), and are therefore conclusive but not sufficient for classification.
