Air Pollution: Particulate matter is one of the components of air pollution, along with gases like nitrogen dioxide and ozone.
PM2.5: PM2.5 refers to fine particulate matter with a diameter of 2.5 micrometers or smaller. These tiny particles are particularly concerning because they can penetrate deep into the lungs and enter the bloodstream.
Respiratory Diseases: Exposure to high levels of particulate matter has been linked to an increased risk of respiratory diseases such as asthma, bronchitis, and lung cancer.
