The main objective of this article is an attempt to use snow as an indicator in the process of assessing and identifying vehicle-derived elements pollution. The aim of the present study is to characterize traffic-related elements in snow collected from three sites: a parking place, a highway and a relatively unpolluted airfield. Several recent studies suggest that road traffic is considered to be one of the major sources of environmental pollution in urban areas. In order to avoid the problem of low emission from household furnaces, samples were collected far away from residential buildings. Snow located near roads with heavy traffic seems to be a very useful tool and indicator of traffic-related elements released into the environment. Snow acts as a natural filter for various chemical elements and particles. Snow is an efficient scavenger of aerosol and air pollutants, usually remains on the ground for sampling after the event, moreover, snowmelt contaminates soil. In the present study filtered (0.45 µm) samples of melted snow were analyzed with ICP-MS. The results show significantly higher concentrations of elements in snow collected at the parking lot and at the highway when compared to samples taken from a relatively unpolluted airfield. Research on exploitation dust (break, tire, clutch) was performed with SEM-EDS.

This dissertation presents the results of analyses on the particle size distribution and zinc content in street dusts from 3 May Alley (PD) and parking dusts from the Campus of University of Science and Technology (PP) in city of Cracow. The purpose of researches was to determine the impact of communication on the state of urban environment, by presenting the level of Zn contamination in separated dust fractions. According to results, PD are more fine-grained, contain about 2,5 times more fraction < 63 ?m than PP. In this fraction occurred the highest concentration of Zn, from 1054 to 1216 mg/kg (PP) and from 685 to 858 mg/kg (PD).There was observed a relatively higher level of Zn contamination in dusts from parking lots, but by analyzing the load, a street dusts put into the environment more zinc in form of smallest, most dangerous particles. The biggest load of Zn (39,9%) introduced fraction < 63 ?m in street dusts and fraction 200-1000 ?m in parking dusts. There is also a significant effect of transport on Zn content in soils and vegetation, together with the distance from the May 3 Alley Zn content is reducing.
