Fast Facts-

Cadmium is very poisonous. A dose of 10 milligrams can cause symptoms of poisoning like amenia, chest pain, spasms of the anal sphincter, death, etc.

Like zinc, cadmium is used for electroplating for ist good corrosion resistance,lubricity, and compatibility with aluminum.

Though cadmium is toxic, it does play a role for some life-forms. Diatoms, a major group of algae utilze cadmium to carry out their normal functions.

Up to 30 milligrams of cadmium is inhaled throuout childhood.

Skin exposure to cadmium usually causes skin irritation. Many people were very itchy because it was once used for cheap jewelery.

Cadmium costs $3.55 (U.S. currency) per pound.
