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

Abstract: The cryosphere in South America is a very important resource because it is the main source of water for 85 million inhabitants distributed in Colombia, Ecuador, Peru, Bolivia, Chile and Argentina [1-2]. To know the effects due to global phenomena such as arctic oscillation (AO) in the reduction of the cryosphere in this region, we proceeded to analyze sources of reanalysis information (ERA-40; NCEP/NCAR Reanalysis) and high resolution snow cover (MOD10 500m) from Moderate-Resolution Imaging Spectroradiometer (MODIS). Several linear adjustments were made to observe how snow cover variations (Y) responded to variations in AO (X1 ), surface temperature (X2 ) and snow precipitation (X3 ).
