Mankovska, B. (Forest Research Institute, Zvolen (Slovak Republic))
Problems of the environment pollution in Ziarska basin are connected with the operation of Aluminium plant from 1953. After replacement of old production technology by a a new one by Norwegian company Hydro Aluminium emission of dust of Al2O3 dropped from 766 tons per year to 243 tons per year, emission of fluorides dropped from 847 to per year to 65.9 tons per year and of SO2 have increased from 716 to 974 tons per year. The mentioned reduction of emission reflected markedly in a great reduction of vegetation loading by fluorine. In the year 2001 we found statistically sifnificant difference for total Ksupz (coefficient of loading) in coniferous and broadleaved tree species in A polution zone in comparison with the zone B, C and D
