“…In all cases, the magnetic permeability μ of each layer was assumed as equal to that of free space (i.e., μ 0 =4 π × 10 −7 H m −1 ), which holds for nonmagnetic materials as found in litter and soils in most unpolluted environments [e.g., Matysek et al , ; Magiera et al , ].…”

Decomposing litter accumulated on the soil surface in forests plays a major role in several ecosystem processes; its detailed characterization is therefore essential for thorough understanding of ecosystem functioning. In addition, litter is known to affect remote sensing radar data over forested areas and their proper processing requires accurate quantification of litter scattering properties. In the present study, ultrawideband (0.8-2.2 GHz) ground-penetrating radar (GPR) data were collected in situ for a wide range of litter types to investigate the potential of the technique to reconstruct litter horizons in undisturbed natural conditions. Radar data were processed resorting to full-wave inversion. Good agreement was generally found between estimated and measured litter layer thicknesses, with root-mean-square error values around 1 cm for recently fallen litter (OL layer) and around 2 cm for fragmented litter in partial decomposition (OF layer) and total litter (OL + OF). Nevertheless, significant correlations between estimated and measured thicknesses were found for total litter only. Inaccuracies in the reconstruction of the individual litter horizons were mainly attributed to weak dielectric contrasts amongst litter layers, with absolute differences in relative dielectric permittivity values often lower than 2 between humus horizons, and to uncertainties in the ground truth values. Radar signal inversions also provided reliable estimates of litter electromagnetic properties, with average relative dielectric permittivity values around 2.9 and 6.3 for OL and OF litters, respectively. These results are encouraging for the use of GPR for noninvasive characterization and mapping of forest litter. Perspectives for the application of the technique in biogeosciences are discussed.

“…2 and 3) as well as thousands of households using coal for heating caused that the annual total dust emission in the end of 1980s was in Rybnik 35 g m -2 and in 1999 it was even 45 g m -2 . After closing some old plants and modernization of others including application of high efficient precipitators, the annual dust emission was reduced to the amount of 3.2 g m -2 in 2013 (Magiera et al 2015).…”

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).

“…Ultrafine ferrospheres and Al-Si particles emitted into the atmosphere from Fe dendritic crystals (Table 3) can also increase the magnetic susceptibility of topsoil layers. For a long time, these frequencies have been identified in the surroundings of power plants [101][102][103][104][105][106], and with them, the EE content in soil, water, and plants [107][108][109].…”

The purpose of this paper is to assess the content and distribution of some elements in coal from two bituminous coal basins and in fly ash and slag derived from combustion of the coals in six power plants in Poland. The petrographic composition and distribution of elements were characterized in the tested samples, using reflected light microscope, X-ray powder diffractometer, inductively coupled plasma atomic emission spectroscopy, and scanning electron microscope with energy dispersive X-ray. The highest content of elements in coal occurs in siderite. In Al-Si particles, as well as in magnetite with skeletal and dendritic structure crystallized on the surface of Al-Si microspheres or cenospheres included in fly ash size < 0.05 mm and in the magnetic fraction of slag, the highest content of elements was noted. Due to the content of elements, fly ash and slag were considered to be neutral for the soil environment. Correlations, which have not been described before, have been observed between the likely mode of binding of some elements in coal and their distribution in fly ash and slag. These correlations could be of particular value when predicting the content and distribution of elements in combustion residues and in the assessment of their environmental toxicity.
