“…In the snow samples, susceptibility had the strongest correlation with PLI and not with individual elements, which indicated the magnetic concentration to be more proportional to the concentration of collective elements (Yang et al, 2010). Correlations in moss bags, instead, were the strongest between susceptibility and individual elements of Fe and As; Fe, because of its ubiquitous nature, was typically found to have good correlations with susceptibility and this was true also in the snow samples.…”

“…Exploring the relationships between total PAH content and magnetic parameters measured within this study, we found the existence of linear correlations between total PAH content on one side, and M rs /c and B cr , on the other (Figure 11). as good proxies for the degree of heavy metal pollution and PM load [Hoffmann et al, 1999;Muxworthy et al, 2001;Kim et al, 2007;Maher et al, 2008;Mitchell and Maher, 2009;Yang et al, 2010]. Most of the studies report data concerning one city (e.g., single location), where various relative contribution from different pollution sources determine heavy metalmagnetism relationship.…”

“…Vegetation species, growing in a polluted environment are also widely used as a passive bio‐samplers of atmospheric dust and their magnetic signature reflects the degree of anthropogenic contamination in urban environments [ Matzka and Maher , 1999; Hanesch et al , 2003; Jordanova et al , 2003; Lehndorff et al , 2006; Maher et al , 2008; Szönyi et al , 2008; Mitchell and Maher , 2009]. Road dust has also been a subject of detailed magnetic studies for quantification of the degree of environmental pollution in big cities [ Hoffmann et al , 1999; Goddu et al , 2004; Kim et al , 2009; Yang et al , 2010]. Magnetic studies on indoor dust are still rare [ Halsall et al , 2008].…”

[1] Settled indoor and outdoor dusts in urban environment represent an important source of secondary pollution. Magnetic characteristics of the settled dust from six cities in Bulgaria are explored, allowing comparison on a national (country) scale. Monthly variations of the mass-specific magnetic susceptibilities (c indoor ) and (c outdoor ) and calculated dust loading rates for a period of 17 months do not show seasonal variability, probably due to the dominant role of traffic-related emissions and soil-derived particles in the settled dust. The main magnetic mineral is magnetite, present as spherules and irregular particles of pseudo-singledomain grain sizes. Systematically lower remanence coercivities are obtained for outdoor dusts when compared with the corresponding indoor samples, implying that penetration of smaller particles of ambient origin indoors is the main source of the indoor dust. Mean yearly values of the ratio (c indoor /c outdoor ) for each city show statistically significant correlation with mortality due to cardiovascular diseases. This ratio reveals the source-and site-specific importance of the anthropogenically derived toxicogenic fraction. Heavy metal content of the settled dust is related to the contribution from several pollution sources (soil-derived, combustion and industrial), discriminated through analysis of principal components. SEM/EDX analyses reveal abundant presence of anthopogenic Fe-containing spherules, irregular particles and diesel exhaust conglomerates. High molecular weight polyaromatic hydrocarbons (PAH) dominate the total PAH content of the outdoor dust samples. The observed linear correlation between total PAH content, coercivity of remanence and the ratio M rs /c suggest either adsorption of PAHs on iron oxide particles and especially magnetite, or emission related increase in total PAH concentration along with a decrease of effective magnetic grain size of the accompanying magnetic fraction.

“…The most widely spread chemical elements are oxygen, silica, aluminium, iron and a number of others (Baltrėnas and Ščupakas 2007). As geo-accumulation indices show, larger amounts of Cr, Ni, Cu, Pb, Zn and Cd are spread in the natural environments of urbanised territories and closer to roads (Wei and Yang 2010;Christoforidis and Stamatis 2009;Yang et al 2010). The following sequence of heavy metals distribution in soil was identified: Cd>Pb>Zn~Cu>Mn>Ni>Fe~Cr (Maiz et al 1997).…”

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.
