“…It is possible that atmospheric fall-out released from automobile exhaust and coal burning might have contributed to the minor increase of median value compared to our samples. Higher values of v (29-146 � 10 À 8 m 3 kg À 1 ) have been reported for the mixed agricultural and industrial area in south France (Lecoanet, Leveque, and Ambrosl 2003), which is likely due to differences in the soil derived from different parent materials.…”

“…This includes studies in Turkey, Mexico, Estonia and south France etc. (Hay et al 1997;Bityukova, Scholger, and Birke 1999;Lecoanet, Leveque, and Ambrosl 2003;Lourenco et al 2014) which showed that magnetic susceptibility can be used as a proxy for chemical methods due to the fact that pollutants are often closely related to magnetic phases (Canbay, Aydin, and Kurtulus 2010). This is due to the fact that magnetic carriers can often absorb and/or incorporate heavy metals in their crystalline structure (Morton-Bermea et al 2009).…”

The values of magnetic susceptibility and Cu, Zn, Ni, Pb, Cr, Cd concentrations of 70 topsoil samples were analyzed and assessed for soil contamination in the Linfen basin of China. The contamination factor (CF) and pollution load index (PLI) were used to assess the degree of heavy metal pollution. All heavy metal concentrations in the soil were greater than the background values of Shanxi agricultural soils. PLI values ranged from 1.27 to 2.18 indicating significant soil contamination. Principal component analyses and correlation analyses were adopted for data treatment to identify heavy metal sources. Cu, Zn, Ni, and Pb were responsible for 31.2% of the total variance suggesting that these elements mainly originated from agrochemistry and atmospheric deposition. A positive correlation of magnetic susceptibility with Cu and PLI were observed in cultivated soils. This study shows that magnetic susceptibility measurements can be used as a technique in which different types of soil pollution can be distinguished and can also be used to rapidly monitor anomalies in areas that might require expensive and time consuming detailed chemical analyses.

“…prevention measures and land occupation control) are lacking. In addition, urban occupation generates sediment contaminated by toxic substances (heavy metals, pesticides, oils, organic compounds), which can adhere to the fine fractions in the fluvial environment (Robertson et al, 2003;Lecoanet et al, 2003). Primary sources of sediment contamination in urban areas are domestic sewage and the construction of buildings and roadways.…”

“…Anthropogenic magnetic particles present in the uppermost soil horizons are relatively easy to distinguish from natural iron minerals occurring in soils [9,20,31]. However the variety of their forms is considerable and studies initiated in some European institutions indicate that there is a connection between the forms of anthropogenic minerals in soils and their sources of emission [32,33]. In order to determine the genesis of the studied phases in detail, it is crucial to identify characteristics of the same types of particles occurring both in soils and in dusts from a given source.…”

Morphology and mineralogy and magnetic parameters were analysed in atmospheric dust samples collected in 7 cities of Upper Silesia region (South Poland). The study was carried on by means of EDS spectroscopy, SEM technique, X-ray diffraction and Mössbauer spectroscopy. Special attention was paid to the magnetic fraction of studied dusts that is a potential carrier trace elements emitted to the environment. To assess the total content of magnetic fraction in bulk dust samples, mass specific magnetic susceptibility (χ) was measured using a MS2B "Bartington" sensor, then a physical separation of magnetic particles (mostly of technogenic origin) was conducted. The dusts revealed high diversity of χ value, which depended both on the sampling site and the prevailing direction of winds during the period of dust deposition on filters. In the case of atmospheric dusts, the χ value ranged from 10 × 10 -8 m 3 kg -1 to 1577 × 10 -8 m 3 kg -1 . The highest values were detected in samples collected within the range of metallurgical dust emission. The morphological and mineralogical analyses showed that among the technogenic magnetic fraction ferrimagnetic spherules built of iron oxides from magnetite-maghemite series with admixtures of wustite, hematite, goethite and non-stoichiometric Fe-Zn oxides were the predominant structures. Significant differences in magnetic mineralogy of dusts coming from different branches of industry were observed. Magnetic fraction produced by the metallurgy and coke industry were mostly in forms of tightly compacted aggregates with well-formed crystal structure whereas in fly ashes from coal combustion spherical forms (typical ferromagnetic spherules) were mostly observed. Here the predominant magnetic minerals are: magnetite,
