occupational diseases
diseases caused by factors involved in a person's work; there are many types. Dusts are a common cause; fine particles of
silica can lead to silicosis in miners, glassworkers, and persons involved in the manufacture of materials such as cement. Another cause is toxic gases
and vapors, which can result in respiratory disorders and may also involve the blood and other body systems. Many different
substances are toxic; some are therapeutic but in large amounts are toxic. Some chemicals can affect the skin and cause forms
of dermatitis. Working conditions, such as high temperatures or humidity, loud noise, changes in air pressure, or continuous exposure to
sun and wind, can cause disorders such as heat exhaustion, impaired hearing or vision, decompression sickness, or skin conditions.
