In Poland, PM10 fine dust standards are set at three levels:

  • acceptable level 50 μg/m3 (daily)
  • information level 200 μg/m3 (daily)
  • alarm level 300 μg/m3 (daily)

On the other hand, for fine particulates such as PM10 and PM2.5, the European Union has only established an acceptable level. These are: for PM10 – 50 μg/m3 (daily) and 40 μg/m3 (annual average), and for PM2.5 – 25 μg/m3 (annual average only as there a daily measure is not available for this pollutant).

The norms of acceptable daily concentrations established by the World Health Organization are 50 μg/m3 for PM10. and 25 μg/m3 for PM2.5.
