Particulate Matter Pollution

Particulate matter (PM) pollution consists of tiny solid particles and liquid droplets suspended in the air. These particles, small enough to be inhaled deeply into the lungs, come from sources like vehicle exhaust, industrial processes, construction, and natural events like wildfires. PM pollution can harm respiratory and cardiovascular health, especially in vulnerable populations. Measuring the concentration of these particles helps assess air quality. Reducing PM pollution involves controlling emissions from various sources and promoting cleaner technologies to protect public health and the environment.
