The first known U.S. workers' compensation claim for asbestos disease was in 1927. In 1930, the first reported autopsy of a person with asbestosis was conducted in the United States and later presented by a doctor at the Mayo Clinic, although in this case the exposure involved mining activities somewhere in South America.

Mineral dust airway disease is a general term used to describe complications due to inhaled mineral dust causing fibrosis and narrowing of primarily the respiratory bronchioles. [1] It is a part of a group of disorders known as pneumoconioses which is characterized by inhaled mineral dust and the effects on the lungs.
Occupational dust exposure occurs when small particles are generated at the workplace through the disturbance/agitation of rock/mineral, dry grain, timber, fiber, or other material. When these small particles become suspended in the air, they can pose a risk to the health of those who breath in the contaminated air.
Murray indicated that fibrosis of the lungs caused by asbestos dust was a plausible cause of the patient's death. [ 30 ] [ 31 ] The death of English textile worker Nellie Kershaw in 1924 from pulmonary asbestosis was the first case to be described in medical literature, and the first published account of disease definitely attributed to ...
Exposure to coal dust is the cause of coalworker's pneumoconiosis, also called "black lung disease", is an interstitial lung disease caused by long-term exposure (over 10 years) to coal dust. Symptoms include shortness of breath and lowered pulmonary function. It can be fatal when advanced.
NIOSH has set a recommended exposure level of 1 mg/m3 total dust. The ACGIH has recommended a 0.5 mg/m3 Threshold Limit Value for western red cedar based on its asthma effects. Certain species of hardwood —such as oak , mahogany , beech , walnut , birch , elm , and ash — have been reported to cause nasal cancer in woodworkers.
Pneumoconiosis is the general term for a class of interstitial lung disease where inhalation of dust (for example, ash dust, lead particles, pollen grains etc) has caused interstitial fibrosis. [ 1 ] [ 2 ] The three most common types are asbestosis , silicosis , and coal miner's lung . [ 3 ]
Brief or casual exposure to low levels of crystalline silica dust are said to not produce clinically significant lung disease. [45] In less developed countries where work conditions are poor and respiratory equipment is seldom used, the life expectancy is low (e.g. for silver miners in Potosí, Bolivia, is around 40 years due to silicosis).
