Cadmium is primarily consumed for the production of rechargeable nickel cadmium batteries; other end uses include pigments, coatings and plating, and as stabilizers for plastics. Solar cell manufacturing may become another significant market for cadmium in the future.
Cadmium is used to create a range of yellow colors in plastics formulations. Cadmium sulfides and sulfo-selenides are used in pigments to create a family of yellow/orange/red pigments. Cadmium yellow is created using cadmium sulfide (CdS), cadmium red is cadmium selenide (CdSe) and cadmium orange is an intermediate cadmium sulfoselenide.
Exposure Sources of Cadmium. Cadmium and cadmium compounds have been used in various commercial and industrial applications since the early 1900s [19,164,165]. Today, cadmium is primarily used in batteries, though other cadmium-containing products include pigments, electroplates and coatings, and plastic stabilizers.
solders, as a stabilizer in plastics (organic cad-mium), as a pigment, and as a component of nickel-cadmium batteries. Cadmium production may use by-products and wastes from the pri-mary production of zinc. Health Impacts of Exposure Ingestion via food, especially plant-based food-stuffs, is the major route by which cadmium en-
Cadmium occurs as a minor component in most zinc ores and is a byproduct of zinc production. Cadmium was used for a long time as a corrosion-resistant plating on steel, and cadmium compounds are used as red, orange and yellow pigments, to color glass, and to stabilize plastic.
Cadmium sulfide compounds (e.g. cadmium sulfide, cadmium sulfoselenide, and cadmium lithopone) are used as pigments in a wide variety of applications, including engineering plastics, glass, glazes, ceramics, rubber, enamels, artists colours, and fireworks. Ranging in colour from yellow to deep-red maroon, cadmium pigments
Nickel-cadmium batteries Aluminum foil Plastic bags Plastic grocery bags Plastic and foil packaging Aluminum pop can Plastic (No. B2) plate Benzene, naphthalene, styrene, tol-uene, and xylene are aromatic hydrocar-bons, which are suspected carcinogens. Aromatic hydrocarbons also are severe eye, nose, and throat irritants. These compounds occur ...
Recent data on pulmonary uptake of cadmium compounds 20-23 and on the effects of solubility, particle charge, and crystallinity of cadmium compounds 24-26 suggest the need to better characterize the extent of workers' biological exposure to cadmium in various work settings.
· Cadmium was used for a long time as a corrosion-resistant plating on steel, and cadmium compounds are used as red, orange and yellow pigments, to color glass, and to stabilize plastic.
The International Cadmium Association (ICdA) is a non-profit association representing the interests of the world's cadmium industry. Its Members include producers, processors, recyclers and consumers of cadmium metal, cadmium compounds, and products to which cadmium or its compounds have intentionally been added.

Cadmium Oxide (CdO): This compound in used in a variety of reactions including acting as a catalyst in redox reactions, hydrogenation reactions, polymerization and cleavage. Cadmium Oxide is heat resistant so it can be very useful in heat-resistant plastics, as well as other coatings for plastic.
Cadmium Cadmium is a very toxic metal. All soils and rocks, including coal and mineral fertilizers, contain some cadmium. Cadmium has many uses, including batteries, pigments, metal coatings, and plastics. It is used exten-sively in electroplating. Health effects Cadmium and cadmium compounds are known human carcinogens.
Cadmium is also used in paint pigments, for electroplating and in making polyvinyl chloride plastics. The majority of cadmium present in the atmosphere is the result of human activities, especially smelting of non-ferrous metal ores, fossil fuel combustion and municipal waste incineration. 4. Soluble inorganic cadmium compounds are of
The other company, operating in Ohio, recovered secondary cadmium metal from spent nickel-cadmium (NiCd) batteries. Domestic production and consumption of cadmium were withheld to avoid disclosing company proprietary data. Cadmium metal and compounds are mainly consumed for alloys, coatings, NiCd batteries, pigments, and plastic stabilizers.
