What Are the Sources of Respirable Dust Particles?
Respirable dust particles originate from various sources, both natural and man-made. Key sources include:
Industrial operations: Activities such as mining, quarrying, and manufacturing can generate significant amounts of dust. Construction sites: Demolition, excavation, and other construction-related activities release dust into the air. Transport emissions: Exhaust from vehicles, particularly diesel engines, contributes to airborne particulate matter. Agricultural practices: Plowing, harvesting, and other farm operations can generate dust. Natural events: Wildfires, wind erosion, and volcanic eruptions are significant natural sources of respirable particles.
