particulate matter (PM)

Particulate matter (PM) refers to tiny particles or droplets in the air that can be harmful to health and the environment. These particles come from various sources, including vehicle emissions, industrial processes, wildfires, and natural sources like dust. PM is usually classified by its size: PM10 includes particles that are 10 micrometers or smaller, while PM2.5 includes those that are 2.5 micrometers or smaller. Because they are so small, they can be inhaled and can cause respiratory problems, cardiovascular issues, and other health concerns. Reducing PM levels is important for public health and air quality.

    Particulate Matter (PM) refers to tiny particles or droplets in the air that can be inhaled and affect health. These particles vary in size, with PM10 being less than 10 micrometers and PM2.5 being less than 2.5 micrometers. Sources include vehicle emissions, industrial processes, and natural elements like dust and pollen. PM can cause respiratory issues, cardiovascular disease, and other health problems, especially in vulnerable populations. Reducing PM levels is important for improving air quality and public health.

    Particulate matter (PM) refers to tiny solid or liquid particles suspended in the air, which can include dust, smoke, and soot. PM is categorized into two main sizes: PM10 (particles with a diameter of 10 micrometers or smaller) and PM2.5 (particles with a diameter of 2.5 micrometers or smaller), which can penetrate deep into the lungs and even enter the bloodstream. Exposure to high levels of particulate matter can lead to health issues such as respiratory problems and heart disease. It is commonly produced by vehicles, industrial processes, and natural sources like wildfires.
