Cadmium, pronounced kad-mee-uh-m, is a soft bluish-white metal that is used in batteries, nuclear reactor shields, rustproof plating, pigments (bright red, yellow and orange shades) and TVs.

Its use is decreasing due to new technologies and the fact that in certain forms it can be toxic – it accumulates in the body and is known to cause birth defects and cancer.

It’s also found in cigarette smoke, tap water, coffee and in some processed foods and sea foods.

In the lab it’s used in helium-cadmium lasers – a source of blue-ultraviolet laser light, and it’s also used in fluorescence microscopes – which are used for imaging biological tissues.
