Journal of Environmental Engineering and Landscape ManagementPublication details, including instructions for authors and subscription information:Abstract. Vehicles release large amounts of heavy metals to the environment. There have been done a lot of investigations analysing the distribution of heavy metals in soils near intensive regional roads. However, there is lack of investigations into the impact of small-intensity gravel roads on roadside soil contamination with heavy metals. The object of this investigation is four gravel roads of local significance connecting small villages. The intensity of these roads is very low. The gravel roads are chosen according to application of dust-minimizing materials, for example, CaCl 2 and oil emulsion. According to our results, none of the soil samples had an excess of heavy metal concentration limit. Besides, heavy metal concentrations were decreasing with a distance from the road increasing. We can make an assumption that road dust-minimizing materials do not have a significant impact on heavy metal distribution in roadside soils. The major factors of heavy metal pollution distribution in roadside soils are traffic intensity, roadside trenches, and topographic conditions.

The Influence of Road Maintenance Substances on the Growth of Graminaceous Plants

“…Significant concentrations of road maintenance salts (up to 3200 mg/l) accumulate in snow (Baltrėnas, Kazlauskienė 2009b) and enter the soil together with meltwater carrying heavy metals (Vainalavičiūtė et al 2009;Mikalajūnė, Jakučionytė 2011) andoil products (žukauskaitė et al 2008;2012), which negatively affect roadside vegetation (Dobson 1991;Baltrėnas et al 2006;Darginaviciene et al 2008) as well as surface and ground waters (Williams et al 1999) and their fauna (Oškinis, Kaperovičius 2005;Andreikėnaitė et al 2007;Vosylienė et al 2010). As other investigations have shown, soil is alkaline because of cement dust that contains different microelements (Stravinskienė 2011).…”

Pollution reduction investigation of soil and nutritional plants contaminated with lead using natural zeolite

“…Transport system is one of the heavy metals occurrence sources in the environment in Lithuania. The amounts of heavy metals (Cr, Cd, Pb, Ni, Cu, Zn) exceeding the maximum concentration get into the roadside soil during automobile transport exploitation [1][2][3][4].…”

The impact on grass vegetation of materials reducing gravel road dustiness

“…Vehicles release large amounts of heavy metals to the environment. There have been done a lot of investigations analysing the distribution of heavy metals in soils near intensive regional roads (Mikalajūnė, Jakučionytė 2011). As other investigations have shown, soil is alkaline because of cement dust emissions (Stravinskienė 2011).…”
