Dustiness may be defined as the propensity of a finely divided solid to form an airborne dust from a mechanical or aerodynamic stimulus. [1] Dustiness can be influenced by particle morphology (shape), size, and inter-particle forces. Dustiness increases the risk of inhalation exposure. [2]
When a person becomes sensitized to wood dust, he or she can suffer severe allergic reactions (such as asthma or dermatitis) after repeated exposure or exposure to lower concentrations of the dust. [3] Other common symptoms associated with wood dust exposure include skin and eye irritation; nasal dryness and obstruction; and prolonged colds. [3]
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.
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 ]
A common scenario is exposure to moldy grain, hay or woodchips, with farmers and pig workers the most common occupations affected. Those who work with grain, poultry and mushrooms also frequently report symptoms. [1] Wheat harvested has dust blown in the air. Pulmonary reactions occur due to the exposure to grain dust.
People who had dust pneumonia often died. [1] There are no official death rates published for the Great Plains in the 1930s. In 1935, dozens of people died in Kansas from dust pneumonia. [1] Red Cross volunteers made and distributed thousands of dust masks, although some farmers and other people in the affected areas refused to wear them. [1]

The use of personal protective equipment may substantially reduce the risk of adverse health effects from contact with hazardous materials. [2] Long-term exposure to chemical hazards such as silica dust, engine exhausts, tobacco smoke, and lead (among others) have been shown to increase risk of heart disease, stroke, and high blood pressure.
