These health effects have made us more aware of the dangers of exposure to antimony.ДЄntimony can be found in soils, waters and air in very small amounts. It is not known whether antimony can cause cancer or reproductive failure.ДЄntimony is used as a medine for parasital infections, but people who have had too much of the medicine or were sensitive to it have experienced health effects in the past.

Breathing in antimony that is bound to hydrogen in the gaseous phase, is what mainly causes the health effects.Д®xposure to relatively high concentrations of antimony (9 mg/m 3 of air) for a longer period of time can cause irritation of the eyes, skin and lungs.ДЄs the exposure continues more serious health effects may occur, such as lung diseases, heart problems, diarrhea, severe vomiting and stomach ulcers. Human exposure to antimony can take place by breathing air, drinking water and eating foods that contain it, but also by skin contact with soil, water and other substances that contain it. Health effects of antimonyД®specially people that work with antimony can suffer the effects of exposure by breathing in antimony dusts. In Finland there is a deposit of elemental antimony. Annual production is about 50.000 tonnes per year, with virgin materials coming mainly from china, Russia, Bolivia and South Africa. Antimony is an important metal in the world economy. But it also enters the environment through several applications by humans. The ancient Egyptians used antimony, in the form of stibnite, for black eye make-up.ДЄntimony occurs naturally in the environment. Antimony compounds are used to make flame-proofing materials, paints, ceramic enamels, glass and pottery. Antimony alloys are also used in batteries, low friction metals, type metal and cable sheathing, among other products. Antimony is alloyed with lead to increase lead's durability. Very pure antimony is used to make certain types of semiconductor devices, such as diodes and infrared detectors. Antimony makes up about 0.00002% of the earth's crust. Nicolas LГ©mery, a French chemist, was the first person to scientifically study antimony and its compounds.

It is sometimes found free in nature, but is usually obtained from the ores stibnite (Sb 2S 3) and valentinite (Sb 2O 3). Antimony and some of its alloys expand on cooling.ДЄntimony has been known since ancient times. Antimony is a poor conductor of heat and electricity, it is stable in dry air and is not attacked by dilute acids or alkalis.
