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.
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.
Mineral dust is mainly constituted of the oxides (SiO 2, Al 2 O 3, FeO, Fe 2 O 3, CaO, and others) and carbonates (CaCO 3, MgCO 3) that constitute the Earth's crust.The composition of mineral dust, usually named in atmospheric sciences as mineralogy composition, is relevant for different physical and chemical processes in the atmosphere, for example, oxides with iron have an effect in the ...
Exposure to mineral dust presents the hazards for farmers in the development of lung disease. [6] In one analysis, 112 male Hispanic individuals in the Fresno county were part of a study conducted in the findings of the comparison between farm workers and non-farm workers.
Because of work-exposure to silica dust, silicosis is an occupational hazard to construction, railroad, [42] demolition, mining, sandblasting, quarry, tunnelling, [43] ceramics and foundry workers, as well as grinders, stone cutters, stone countertops, refractory brick workers, tombstone workers, workers in the oil and gas industry, [44 ...
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 ]
New maps of the chemical composition of dust based on measurements taken from the International Space Station will help scientists understand which types of minerals contribute to climate change.
Fugitive dust is an environmental air quality term for very small particles suspended in the air, primarily mineral dust that is sourced from the soil of Earth's pedosphere.A significant volume of fugitive dust that is visible from a distance is known as a dust cloud, and a large dust cloud driven by a gust front is known as a dust storm.
