How is cadmium used in everyday life?

Cadmium became an important metal in the production of nickel-cadmium (Ni-Cd) rechargeable batteries and as a sacrificial corrosion-protection coating for iron and steel. Common industrial uses for cadmium today are in batteries, alloys, coatings (electroplating), solar cells, plastic stabilizers, and pigments.

Will cadmium plating rust?

Cadmium provides tough corrosion resistance in part because the finish is “sacrificial.” That is, cadmium “sacrifices” itself to protect the metal it covers. of cadmium will withstand 96 hours of salt spray before the cadmium coating begins to corrode, and at least 148 hours before the iron substrate begins to rust.

Due to slow excretion, cadmium accumulates in the body over a lifetime and its biologic half life may be up to 38 years.

How is cadmium poisoning treated?

Cadmium intoxication was treated successfully with the oral administration of edathamil calcium disodium. The mechanism of the process is replacement of the calcium ion in the chelating agent by a cadmium ion and the excretion of the chelate in a nonirritating form through the kidneys.

Eating vegetables, plants, seafood or liver or kidneys containing cadmium is how most people get cadmium into our bodies. Smoking cigarettes is another common way cadmium enters our bodies.
