“…Consequently, the presence of TMPs in topsoil (mainly in the organic horizon) is considered an indicator for heavy metal soil pollution. This fact was confirmed by many authors (Veneva et al 2004;Klose and Makeschin 2005;Spiteri et al 2005;Blaha et al 2008;Jordanova et al 2008;Lu et al 2008;Magiera et al 2008;Bućko et al 2011). Soil with natural plant cover, particularly forest soil, is often used as a target for magnetic susceptibility studies because it exhibits the stratigraphic sequence of the depositing dusts in undisturbed soil horizons for a long time.…”

“…6). Concentrations of such particles are generally considered indicators of technogenic pollutants brought about by fossil fuel combustion and steel works activities (Thompson and Oldfield 1986;Kapička et al 2001;Evans and Heller 2003;Boyko et al 2004;Spiteri et al 2005;Magiera et al 2006aMagiera et al , b, 2007Magiera et al , 2008Rothwell and Lindsay 2007). The effect of natural pedogenic processes that were sometimes observed in Podzols or Gleysols (Magiera et al 2006a) in studied soil profiles was not detected.…”

Volume magnetic susceptibility (j) was measured on the soil surface and in the vertical topsoil profile within a 300 km 2 area located in an urban-industrial conurbation. The results were compared to plant species compositions in the forest storeys, elevation above sea level, and terrain geomorphology. The content and mineral composition of the magnetic fraction were determined in the soil horizons. It was found that the extent of the area with enhanced topsoil magnetic susceptibility was similar to the dominant wind direction (south-west). Enhanced j values were observed for the soil at the forest margin on the leeward side of the emitters as well as at sites located on exposed local elevations (C10 m). There were no significant correlations between species composition of the forest stand and soil surface j value (measured both with and without forest litter). Soil covered with deciduous treesmostly ash (Fraxinus excelsior L.)-demonstrated higher j values than soil under coniferous tree species. However, our results suggest that this parameter is not controlled by individual tree species, but rather depends on distance from emission sources, intensity of magnetic particle emission, and meteorological conditions (prevailing wind directions and dynamics).

“…These particles are typical of industrial emissions that involve the burning of fossil fuels (Flanders, 1994) and are reported in several studies (e.g. Gomes et al, 2008;Kim et al, 2009;Magiera et al, 2008;Maher, 2011;Spiteri et al, 2005;Yan et al, 2011;Yang et al, 2011). Atmospheric deposition of fly ash on land surfaces and vegetation cover leads to an enhanced magnetic signal (e.g.…”

Magnetic, geochemical and pedological characterisation of soil profiles from different environments and geological backgrounds near Coimbra, Portugal

et al. 2014

This study presents an application of environmental magnetism techniques for the characterisation of the soils near Coimbra (central Portugal). Magnetic measurements, scanning electron microscopy and geochemical studies were carried out on samples collected in 6 soil profiles in order to find possible relationships and to interpret environmental implications. Magnetic susceptibility, saturation isothermal remanent magnetisation and isothermal remanent magnetisation at the backfield of 100 mT and 300 mT were measured. HardIRM %, SIRM/χ and S-ratios were also calculated. Polluted soils showed higher values of magnetic parameters in the superficial soil horizons closer to the roads, plants and urban areas. The lowest values were observed in the deeper horizons of the soil and in the areas least disturbed by human activity. The magnetic results also suggested that the magnetic signal of these soils is mainly influenced by ferrimagnetic magnetite-like minerals and with only a minor contribution from antiferromagnetic carriers (such as hematite minerals). In unpolluted soils, lithogenic contribution is reflected by the enhancement of magnetic susceptibility near parental rock material. Scanning electron microscope images of the topsoil samples revealed the presence of magnetic spherules typical of vehicular exhaust and combustion processes. This evidence suggests that the atmospheric deposition of fly ash is the main reason for the enhancement of the magnetic signal in the topsoil. Chemical analyses showed that the concentration of various heavy metals was higher than the mean background values for Portuguese soils, and higher in superficial soils. Heavy metals showed significant positive correlation with magnetic properties. The conclusions highlight the importance of using environmental magnetism methods and techniques in the evaluation process of soil evolution and pollution history throughout time.

“…The method is based on the fact that industrial fly-ashes contain about 10% of ferrimagnetic particles, namely Fe-oxides (Flanders, 1994;Kapička et al, 2001). Magnetic susceptibility of soils was mapped in surroundings of local sources of pollution (Kapička et al, 1999;Hanesch and Scholger, 2002;Spiteri et al, 2005;Sharma and Tripathi, 2007), or at regional to national scales (Hay et al, 1997;Heller et al, 1998;Magiera and Strzyszcz, 2000;Kapička et al, 2008). Ferrimagnetic particles are usually accumulated at the soil surface.…”

Study is focused on the numerical modeling of fly-ash transport in three sands, which was experimentally studied in the laboratory. Sands were packed in glass cylinders with diameter of 5.52 cm and height of 18 cm. Sands were also packed in plastic cylinders with diameter of 30 cm and height of 40 cm. The fly-ash and pulse infiltrations were applied on the top of all cylinders. Visually observed and gravimetrically evaluated fly-ash migration in small cylinders corresponded to fly-ash mobility in large columns detected using the SM400 Kappameter. The HYDRUS-1D code was used to simulate observed fly-ash transport. Parameters of soil hydraulic functions were either obtained using the Tempe cells and the RETC program or estimated using numerical inversion of transient water flow data measured in both types of columns using HYDRUS-1D. Parameters characterizing colloid transport in sands were then estimated from the final fly-ash distribution in sandy columns using attachment/detachment concept in HYDRUS-1D. Fly-ash mobility increased with increasing sand particle sizes, e.g. pore sizes. Particle sizes and pore water velocity influenced the attachment coefficient, which was calculated assuming filtration theory. The same longitudinal dispersivity, sticking efficiency and detachment coefficient sufficiently characterized fly-ash behavior in all sands. Studie je zaměřena na numerické modelování transportu úletového popílku ve třech píscích, který byl experimentálně studován v laboratoři. Písky byly nahutněny ve skleněných válcích o průměru 5,52 cm a výšce 18 cm. Písky byly také nahutněny v plastových válcích o průměru 30 cm a výšce 40 cm. Na povrchu válců byly aplikovány jednorázové infiltrace vody s popílkem. Migrace úletového popílku pozorovaná vizuálně a zjištěná gravimetricky v malých válcích odpovídala mobilitě úletového popílku detekované Kappametrem SM400 ve velkých válcích. Pozorovaný transport úletového popílku byl simulován programem HYDRUS-1D. Parametry hydraulických funkcí byly získány buď pomocí Tempských cel a programu RETC nebo odhadovány numerickou inverzí transientních data měřených na obou typech válců programem HYDRUS-1D. Parametry charakterizující transport koloidů v píscích byly potom odhadovány z konečné distribuce úletového popílku v písčitých sloupcích užitím konceptu attachment/detachment (připojení/odpojení) v programu HYDRUS-1D. Mobilita úletového popílku se zvyšovala se zvyšující se velikostí písčitých zrn, tj. s velikostí pórů. Velikost zrn a pórová rychlost ovlivnila depoziční (attachment) koeficient, který byl počítán na základě filtrační teorie. Stejné hodnoty podélné disperze, efektivity blokování (sticking efficiency) a mobilizačního (detachement) koeficientu charakterizovaly chování úletového popílku ve všech píscích.KLÍČOVÁ SLOVA: písek, migrace úletového popílku, magnetická susceptibilita, numerická simulace, attachment/detachment koncept, filtrační teorie.
