coarse particulate matter (PM10)

Coarse particulate matter (PM10) refers to tiny particles in the air that are between 2.5 and 10 micrometers in diameter—about one-seventh to one-fifth the width of a human hair. These particles originate from sources like construction sites, road dust, and natural events such as windblown dust or pollen. Because of their size, PM10 can be inhaled into the lungs and may cause health issues, especially for sensitive groups like children, the elderly, and those with respiratory conditions. Monitoring PM10 helps assess air quality and protect public health.
