Antimony (Sb) is in the fourth row of group 5A (IUPAC group 15) in the periodic table, residing between arsenic and bismuth. Antimony displays four oxidation states: -3, 0, +3, and +5. The most common and stable oxidation states of antimony in aqueous solutions and biological fluids are Sb(III) and Sb(V).

The main phases are antimony sulfate (Sb 2 (SO 4) 3), antimony trisulfide (Sb 2 S 3), metallic antimony (Sb), and antimony oxides (Sb 2 O 3 or Sb 2 O 4). It can also be seen that Sb 2 O 3 or Sb 2 O 4 are the stable phases in the dust in the experimental conditions, which is consistent with the analysis results of Figs. 2 and 3.
