You can check on the air pollution map online:
- CO concentration (ppbv - part per billion by volume )
- dust mass (µg/m3)
- SO2 mass (µg/m3)
- ozone layer (DU - Dobson unit)
See on the map what is the concentration of dust in the air.
The largest air pollution occurs in industrial areas, eg in China and in countries where the houses are heated with coal. Air pollution also arises in large cities where there is a poor air flow resulting in a smog.

Large air pollution has a negative impact on health. People often use anti-fog masks to at least protect themselves from harmful dusts.
