Influence of emissions on the stoma apparatus of the Norway spruce (Picea abies) in the whole territory of the Tatra National Park (TANAP) was observed. The achieved results confirmed the occurrence of firm airborne emissions in the spruce needle stomata on the all studied areas in the TANAP. The X-ray analysis confirmed that the circular emissions contain Al-Si-Ca elements and circular-angular ones Al-Si-S, Al-Si-K-Mg and Al-Si-S-Fc elements. It is possible to state that the main elements in emissions are silicium, sulphur and aluminium.
