An indicator that describes the concentration of solid particles in air or gases, usually expressed in milligrams per cubic meter (mg/m³) or the number of particles by size fractions.
Shows the physical quality of air or gas, which affects health, technological processes and environmental conditions
High dust concentrations can increase the risk of respiratory diseases, promote allergies, reduce visibility, cause equipment wear or contaminate products
Solid particles are often associated with industrial activities, transport, combustion processes or natural phenomena (e.g. wind-borne soil particles)
In occupational health and safety assessments (work environment air quality, impact on employees)
In industrial facility control (filtration system efficiency, emission monitoring)
In environmental studies (air pollution assessment, climate impact analysis, public health monitoring)
