Figure 1. The locations for PM concentration monitoring and PSD sampling: (a) Schematic layout of the measured laying hen house with LCAU; and (b) Vertical plan of the LCAU.
Figure 2. Classification of the PM composition based on hierarchical cluster analysis in the days with different atmospheric air quality. Date with green background – Excellent air quality (AQI: 0– 50); Yellow – Good (AQI: 50– 100); Orange – Lightly polluted (AQI: 100– 150); Red – Moderately polluted (AQI: 150– 200).
