PM2.5, or particulate matter with a diameter of 2.5 micrometers or smaller, can penetrate deep into the lungs and even enter the bloodstream. Exposure to PM2.5 is associated with respiratory and cardiovascular issues, such as aggravated asthma, heart attacks, and decreased lung function. Long-term exposure can lead to more severe health problems, including chronic respiratory diseases and increased mortality risk.
