Fine Particulate Matter, often referred to as PM2.5, consists of tiny particles in the air that are less than 2.5 micrometers in diameter. These particles can originate from various sources, including vehicle emissions, industrial processes, and natural events like wildfires. Due to their small size, they can easily penetrate deep into the lungs and even enter the bloodstream. Exposure to PM2.5 can have serious health effects, including respiratory and cardiovascular issues. Because of its ability to travel long distances in the atmosphere, fine particulate matter can affect air quality in areas far from its source, making it a significant environmental concern.
