Byssinosis [n 1] is an occupational lung disease caused by inhalation of cotton or jute dust in inadequately ventilated working environments and can develop over time with repeated exposure. [ 2 ] [ 3 ] Byssinosis commonly occurs in textile workers who are employed in yarn and fabric manufacture industries.
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]
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 ]
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.
Despite lower respiratory effects among all children, there was a significant difference in health outcomes between children with pre-existing conditions and children without. [15] Children with pre-existing conditions were at greater risk that can likely be attributed to the greater disruption of care in the face of flooding and natural disaster.
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]
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.

The airways and lungs receive continuous first-pass exposure to non-toxic and irritant or toxic gases via inhalation. Irritant gases are those that, on inhalation, dissolve in the water of the respiratory tract mucosa and provoke an inflammatory response, usually from the release of acidic or alkaline radicals.
