Sažetak
Artificial snow is used and produced in periods and areas with little snow or no snow at all so that the skiing season could be prolonged. Various impacts on the environment induced by artificial snow production are addressed. The snow samples were collected on Medvednica Mountain near Zagreb, Croatia, from ski race track where FIS World Cup race, “ Snow Queen” is held. They were collected in February 2005, and February 2006, after the sport event was held, and in April 2005, at the beginning of snowmelt season. The collected samples were analyzed in laboratory after melting into water. Inductively coupled plasma atomic emission spectrometry (ICP-AES) was used for metal content determination. Sample preparation procedures were based on preconcentrations from large volume of melted snow. Higher concentrations of alkaline and alkaline earth metals compared to natural snow were obtained for artificial snow samples. Chemical modifications of snow piste conditions were established. The results obtained for essential and toxic metals and non-metals content show different elemental composition of artificial snow compared to natural snow and water. Possible impact of added salts on natural water reservoir is discussed.
