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.
There are two primary types of dust exposure in agriculture: inorganic and organic. Often the cause of allergy illnesses like asthma, organic dusts come from both plant and animal sources. Inorganic dust illnesses are non-allergic lung reactions that originate in the soil. [4] Asthma-like symptoms are linked to inorganic dust syndrome.
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.
Inhalation is a critical but understudied route of MNP exposure, with airborne MNPs originating from urban dust, synthetic fibers from textiles, rubber tires, and household plastic items. [ 43 ] [ 10 ] These airborne particles may become suspended in the air due to wave action in aquatic environments or the spread of wastewater treatment sludge ...
Children with a mutation in a gene called MET, combined with high levels of exposure to air pollution, may have increased risk. [48] Prenatal and early childhood exposure to heavy metals, like mercury, lead, or arsenic; altered levels of essential metals like zinc or manganese; pesticides; and other contaminants cause concern. [48]
Desert lung disease may be related to Al Eskan disease, a lung disorder thought to be caused by exposure to sand dust containing organic antigens, which was first diagnosed after the 1990 Gulf war. [57] The relative importance of the silica particles themselves and the microorganisms that they carry in these health effects remains unclear. [58]
Inhalation is a major route of exposure that occurs when an individual breathes in polluted air which enters the respiratory tract. Identification of the pollutant uptake by the respiratory system can determine how the resulting exposure contributes to the dose .
