    Particulate Matter (PM) refers to a mixture of tiny solid particles and liquid droplets found in the air. These particles can include dust, dirt, soot, and smoke, and they vary in size, with PM10 and PM2.5 being common classifications based on their diameter in micrometers. PM2.5, in particular, can penetrate deep into the lungs and even enter the bloodstream, posing significant health risks such as respiratory and cardiovascular issues.
