“…Our previous study showed that significant correlation between magnetic properties (χlf and SIRM) and heavy metal contents (Cd, Cu. Pb and Zn) existed in urban soils (Lu and Bai 2006;Lu et al 2007). In order to establish the correlation of heavy metal content and magnetic concentration-related parameters, linear regression analysis were done for the soil samples from Zone I, Zone II, and suburban and rural areas (Zones III-VIII), respectively.…”

The accumulation of heavy metals (Cd, Cr, Cu, Pb and Zn) and magnetic minerals in soils along an urban-rural gradient in the rapidly growing Hangzhou City, Eastern China, was measured. The analytical results indicated that heavy metal concentrations, magnetic susceptibility (chilf) and saturation isothermal remnant magnetization (SIRM) in soils decreased with increasing distance from the urban center. The significant relationships existed between heavy metal concentrations, chilf and SIRM and distance from the urban center. The soils in the urban areas were enriched with Cd, Cu, Pb and Zn. Elevated concentrations of heavy metals (especially Cd and Zn) in urban areas indicated the evidence for the accumulation of heavy metal contaminants from anthropogenic activities. Enhanced heavy metal concentrations and magnetic susceptibility were located in the uppermost soil horizons (0-10 cm), decreasing downwards to background values. The significant positive correlations between the Tomlinson Pollution Load Index (PLI) and magnetic susceptibility and SIRM were observed in polluted soil samples. Strong positive correlation indicated that magnetic screening/monitoring provided a fast and non-destructive tool, which can be effectively used as a proxy to detect environmental pollution in rapidly growing urbanization regions affected by anthropogenic activities.

“…Magnetic properties of marine sediments can often contribute reliable information on environmental change (Kumar et al 2005;Sangode et al 2007;Yang et al 2008;Alagarsamy 2009;Zheng et al 2010) and magnetic parameters such as magnetic susceptibility (MS) became a kind of basic data for marine sediment research (Evans and Heller 2003;Yim et al 2004;Ghilardi et al 2008;Meena et al 2011). As a fast and cost-effective parameter, MS also has been successfully used as a proxy for the detection of anthropogenic pollution caused by metallurgical dusts, fly ashes from power plants and urban airborne particulates (Bityukova et al 1999;Jordanova et al 2003;Gautam et al 2004;Lu et al 2007). Furthermore, previous studies have shown the potential of magnetic properties for assessment of pollution in coastal areas (Plater et al 1998;Plater and Appleby 2004;Ridgway and Shimmield 2002;Martins et al 2007).…”

Magnetic mineralogy and its implication of contemporary coastal sediments from South China

Magnetic parameters have been widely used as a rapid, cost-effective, and non-destructive method. To assess whether their magnetic properties reflect the development history in the Pearl River Delta, three sediment cores collected from South China coastal waters were selected for magnetic research. The results indicate that the predominant ferrimagnetic mineral is magnetite, with an additional smaller amount of surprisingly high-coercive greigite. Fine-grained superparamagnetic and singledomain particles of magnetite and the relative contribution of greigite are increased when the total concentration of ferrimagnetic minerals is higher. Three well-known stages of the Chinese history, i.e., iron smelting, cultural revolution, and the latest phase of opening and reforming were identified in the vertical variation of magnetic concentration parameters. Although the record of the three cores is not completely consistent, the results point out that magnetic concentration parameters can reflect the development and pollution history in surrounding coastal areas.

“…There is a wide range of other applications of magnetic properties for assessing soils, such as for hydric soil delineation (de Jong 2002;Grimley et al 2004) or soil pollution assessment (e.g. Kapička et al 2003Magiera et al 2006;Lu et al 2007;Kodešová et al 2011;Dlouhá et al 2013).…”

Jakšík O., Kodešová R., Kapička A., Klement A., Fér M., Nikodem A. (2016): Using magnetic susceptibility mapping for assessing soil degradation due to water erosion. Soil & Water Res., This study focused on developing a method for estimating topsoil organic carbon content from measured massspecific magnetic susceptibility in Chernozems heavily affected by water erosion. The study was performed on a 100 ha area, whereby 202 soil samples were taken. A set of soil samples was divided into 3 subsets: A (32 samples), B (67 samples), and C (103 samples). The mass-specific magnetic susceptibility using low (χ lf ) and high (χ hf ) frequency, and organic carbon content were measured at all soil samples. The contents of iron and manganese, extracted with a dithionite-citrate solution (Fe d , Mn d ) and ammonium oxalate (Fe o , Mn o ), were quantified in A and B samples. Models for predicting organic carbon content from magnetic susceptibilities were designed as follows: (1) subset A was used as the training set for calibration, and subsets B and C were used as the test sets for model validation, either separately (subset B only), or together (merged subsets B and C); (2) merged subsets A and B were used as the training set and subset C was used as the test set. Results showed very close correlations between organic carbon content and all measured soil properties. Obtained models relating organic carbon content to mass-specific magnetic susceptibility successfully predicted soil organic carbon contents.
