Particulate Matter (PM) refers to tiny particles or droplets in the air that can be harmful to human health and the environment. These particles can come from various sources, including vehicle emissions, industrial processes, and natural events like wildfires. PM is categorized by size, with PM10 and PM2.5 being the most commonly referenced, indicating particles with diameters of 10 micrometers and 2.5 micrometers, respectively. Exposure to high levels of particulate matter can lead to serious health issues, including respiratory problems, cardiovascular diseases, and even premature death. Monitoring and regulating PM levels is crucial for maintaining air quality and protecting public health, making it a significant focus for environmental agencies worldwide.
