Description :
The research presented assesses the spatial variability to the physical and chemical properties of snow cover near the ArcelorMittal Poland steel plant in Kraków. Analysis of snow samples collected at 40 different sampling sites. Revealed that dissolved solids were present at six times the concentration in snow 2 km as opposed to 8 km from the steel plant (0.98 v 0.16 meq•dm-3). Reaction ranged from moderately alkaline (8.54 pH max) in snow 2 km from the plant to moderately acidic (4.87 pHmin) at a distance of 8 km. Overall, the spatial variability to snow characteristics (e.g. Ca2+, Mg2+) exhibited a concentric pattern around the steel plant, albeit with a tendency towards elongation in an easterly direction (pH, F-). Ca2+, Mg2+, and SO42- concentrations were nevertheless one or two orders of magnitude lower than those obtained in 1977 and 1978. – (BJ)
