What is Antimony?
The element antimony (Sb) is a silvery white, brittle solid. Antimony along with arsenic and bismuth, belongs to group VA of the periodic table.
Antimony is present in the Earth's crust at a concentration of about 0.2-0.5 mg/kg. It is seldom found in the environment as a pure element, but it is often found as trivalent and pentavalent sulphides and chlorides. A major source of antimony is its recovery as a by-product from lead smelting operations.
Health risks of Antimony on humans.
The health risk of Antimony in humans is very smill.
The maximum acceptable concentration (MAC) for antimony in drinking water is 0.006 mg/L (6 µg/L).
Acute intoxication is characterized by abdominal pain, vomiting, diarrhoea, dehydration, muscular pain, shock, haemoglobinuria, anuria and uraemia.
Uses of Antimony.
Antimony compounds have been used for a long time as therapeutic agents for parasitic diseases such as schistosomiasis, leishmaniasis, trypanosomiasis and ulcerative granu-loma.
Alloys of antimony are used in the manufacture of batteries, cable sheathing, printing type, plumbing solder and antifriction materials; non-metal antimony products are used in flame retardant materials, paint pigments, ceramic enamels, plastics, glass and pottery, ammunition primers and fireworks.
