Cadmium poisoning can also occur in certain workplaces where cadmium is either used in the process or generated as a byproduct. By means of occupational exposure, workers can be exposed to high cadmium levels and experience its toxic effects over time while smelting and mining for other metals Cadmium is a naturally occurring toxic metal with common exposure in industrial workplaces, plant soils, and from smoking. Due to its low permissible exposure in humans, overexposure may occur even in situations where trace quantities of cadmium are found. Cadmium is used extensively in electroplating, although the nature of the operation does not generally lead to overexposure

Cadmium is used in low-melting alloys, especially solder. It is also used in electroplating, paint pigments (cadmium sulfide is the common pigment cadmium yellow) and rechargeable batteries (ni-cads). Cadmium absorbs neutrons and is used in the control rods that dampen nuclear reactions in fission reactors sources of cadmium include the mining and smelting of zinc-bearing ores, the combustion of fossil fuels, waste incineration, and releases from tailings piles or municipal landfills ( UNEP, 2008 ; ATSDR, 2008). 1.4.1 Natural occurrence In the earth's crust, cadmium appears mainly in association with ores containing zinc
