Particulate matter is categorized based on size, with PM10 and PM2.5 being critical for understanding air quality and health risks.
The aerodynamic diameter of particles determines their settling velocity and ability to penetrate into the respiratory system.
Health concerns associated with particulate matter vary by size, with smaller particles posing greater inhalation risks and potential health impacts.
Tiny solid or liquid particles suspended in the air, categorized by size, such as PM10 and PM2.5.
The diameter of an equivalent spherical particle of density 1 g/cm³ that has the same settling velocity as the particle in question.
The constant speed that a particle reaches when the force of gravity is balanced by the drag force of the surrounding fluid.
The process by which particles collide with a surface due to their momentum as the airflow direction changes.
The erratic movement of particles suspended in a fluid as a result of collisions with fast-moving molecules in the gas or liquid.
