Anthropogenic loading of all tree species in Ziarska valley [Ziar nad Hronom, Central Slovakia], expressed by means of the coefficient of loading by air pollutants Kz has decreasing trend. Total loading of all tree species by air pollutants in Ziarska valley (pollution zones A, B, C) expressed by means of Kz coefficient represents in 2001 only 5.9 times higher compared with 7.9 higher loading compared with 2000; 19.4 times higher loading compared with in 1997; 22.9 times higher loading compared with 1996 and 29.5 times higher loading compared with 1995. Total loading by air pollutants for all tree species (pollution zones A, B, C, D) within 50 km from SLOVALCO, a.s. given by Kz represents 3.7 times higher loading. We found statistically significant difference for Kz in coniferous tree species (1 and 2 years old) and broadleaved tree species in A zone in comparison with the zone B, C and D. We also found statistically insignificant difference in coniferous tree species (1 and 2 y) and in broadleaved tree species in the zones B, C and D except for broadleaved tree species, for which we found statistically significant increase between the zone B and D.
