What does it all mean?
PM 10 is particulate matter of 10 micrometers or less in diameter. It can increase the number and severity of asthma attacks, cause or aggravate bronchitis and other types of lung inflammation, and reduce the body’s ability to fight off infections. PM 2.5 is smaller (up to 2.5 micrometers) and able to travel deeply into the respiratory tract, reaching the lungs and even the bloodstream. Exposure to fine particles can cause respiratory and circulatory inflammation and produce asthma-like symptoms.
