Exposure to ambient air pollution
The mean ambient air pollution of particulate matter with an aerodynamic diameter of 2.5 μm or less (PM2.5) in country urban areas ranges from less than 10 to over 100 μg/m3. In urban areas, the mean concentration of particulate matter with an aerodynamic diameter of 2.5 μm or less (PM2.5) ranges from less than 10 to over 100 μg/m3, and from less than 10 to over 200 μg/m3 for particulate matter with an aerodynamic diameter of 10 μm or less (PM10)
