NCIt definition : A dark brown colored, crystalline, inorganic compound that forms toxic fumes of cadmium
oxides when heated. Calcium oxide is mainly used in nickel-cadmium batteries, but
is also used in electroplating, in the production of plastics and nitrile rubbers
and as a nematocide and ascaricide in swine. Exposure to this substance irritates
the eyes, skin and respiratory tract and causes damage to the lungs resulting in shortness
of breath, chest pain and pulmonary edema, and can also damage the kidneys causing
proteinuria and decreased renal function. Calcium oxide is a known carcinogen and
is associated with an elevated risk of developing lung cancer. (NCI05);
