Antimony | Minerals Education Coalition

Antimony is also used for pigments in plastics, paints, rubber, and for a wide variety of minor uses, including medicines, fireworks and others. Antimony oxide is a brilliant yellow color, accounting for much of the pigment use. A tiny amount of highly purified antimony metal is used in the computer industry to make semiconductors.

Arsenic Wikipedia

Arsenate (+5 oxidation state) is the dominant form of arsenic in surface water, while arsenite (+3 oxidation state) is the dominant form in hypoxic to anoxic environments. Arsenite is more soluble and mobile than arsenate. Many species of bacteria can transform arsenite to arsenate in anoxic conditions by using arsenite as an electron donor.
