Occupational medicine: principles & practical applications. Zenz C, ed., Chicago: Year Book Medical Publishers, Inc., 1977 Jul; :843-868
Of all the occupational health aspects of particular concern to professional workers in the disciplines involved with occupational medicine, industrial hygiene and safety, the role of carcinogenic agents is the most vexing and perhaps the most poorly understood. A vast body of scientific evidence has been accumulated demonstrating relationships between occupational exposures and the development of cancers. Hazards range from actinic or solar ultraviolet effects of exposure outdoors to those workers engaged in deep underground mining. The "mixed dusts" , consisting of iron oxide and silica in various ratios or quantities, also have been suspected and are discussed in Chapter 10. Other suspected or implicated agents are arsenic, asbestos, beryllium, cadmium, chromium, cobalt, iron, nickel, radioactive substances, certain aromatic amines and their derivatives, and, most recently, vinyl chloride, discussed in depth elsewhere in this book.
