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.
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 ...
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.
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.

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.
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]
Acute exposure can also lead to long-term neurological effects such as cognitive and behavioural changes. Severe CO poisoning may lead to unconsciousness, coma and death. Chronic exposure to low concentrations of carbon monoxide may lead to lethargy, headaches, nausea, flu-like symptoms and neuropsychological and cardiovascular issues. [28] [26]
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.
