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.
The Roman lead smelting has led to evidence of global pollution. Greenland ice cores from 500 BCE to 300 CE show measurably elevated lead content in the atmosphere. In the USA there are 400 forgotten lead smelting firms that operated in the 1930s to 1960s and may have deposited dangerous levels of lead contamination in nearby soil.
