“…Arsenic distribution in the urban environment is due to emission of fossil fuel combustion, industrial activities, widespread use of pigments, pesticides and other human activities reported in recent years (O'Neill, 1990;Tsai et al, 2003). Moreover, some gasoline was reported to contain 30-120 ng g − 1 of As (Nakamoto, 2000). Coal burning, municipal solid waste incineration, electronic, paper, and pharmaceutical industries were identified as the major sources of anthropogenic emission of Hg (Biester et al, 2002;Tack et al, 2005).…”

“…The source of Ni and Cr in street dust is believed to be the corrosion of cars [3,4], and Cr and Pt of some motor vehicle parts [5]. Moreover, some sorts of gasoline contain 30-120 ng g −1 of As [6] and 0.2-3.3 ng g −1 of Hg [7]. Traffic and roads are one of the largest sources of metal pollution, because the number of vehicles in developing countries has been progressively increasing in recent years.…”

This paper presents a quasi-empirical model of the distribution of pollutant particles along the roadway. By modelling the source of the pollutant as a cut-off cylinder we assume that aerosol particles (of 0.3-15 µm in diameter) are distributed according to the Gaussian law both along the vertical and horizontal axes. A cross wind translates the pollutant cloud away from the road and the particles are being influenced by gravity, particle buoyancy and thermal plume rise effects. The obtained pollutant concentration function coincides well with the experimental data obtained by Zhu et al. (2011), Grigalavičienė andRutkovienė (2006), andZechmeister et al. (2005).

In order to assess the effect of "overuse" in natural parks, roadside soil and dusts were collected from Kamikochi, Chubu Sangaku National Park (Kamikochi) to Matsumoto City, Nagano Prefecture, Japan. Also, the concentrations of As, Sb, Hg and 5 other heavy metals (Ni, Cu, Zn, Cd, Pb) were measured. The higher concentrations of these 8 elements were observed at Kamikochi Bus Terminal, Kama Tunnel, Matsumoto Interchange and the east exit of Matsumoto Station. These 4 sites are strongly affected by the presence of automobiles, which is believed to be responsible for the higher concentrations. Moreover, the concentrations were increased in the summer, probably due to the corresponding traffic volume, related to the tourist season. Many significant positive correlations among the 8 element concentrations were found as well. The information above suggested that As, Sb and Hg distributions are closely related to automobiles, which play an important role in transportation of visitors, meaning the anthropogenic pollution.
