Particle matter (PM)

Particulate matter (PM) refers to tiny particles or droplets suspended in the air, which can originate from sources like vehicle emissions, industrial processes, and natural events such as wildfires. These particles vary in size, with PM10 being larger and PM2.5 being smaller; the smaller particles are more dangerous because they can penetrate deep into the lungs and bloodstream. Exposure to PM can cause health problems such as respiratory issues, heart disease, and worsen existing conditions. Monitoring PM levels is important for assessing air quality and protecting public health, especially in urban and industrial areas.
