Global PM10 AQI Map

This is an interactive global PM10 AQI map that shows the local PM10 index in real time based on the user’s location. Users can also drag the map to explore PM10 conditions worldwide, understand regional differences in air quality, and use it as a reference for travel and health protection.

What is PM10

PM10 refers to inhalable particulate matter with a diameter of less than 10 micrometers, about 1/7 the width of a human hair. Although larger than PM2.5 and less likely to penetrate deep into the alveoli, these particles can still enter the respiratory tract, causing coughing, asthma, and respiratory irritation. Long-term exposure to high concentrations of PM10 may also negatively affect respiratory and cardiovascular health.
