Mexico City topsoils: Heavy metals vs. magnetic susceptibility

Assessment of bioavailability of some potential toxic metals in mining-affected soils using EDTA extraction and principle component analysis (PCA) approach, Derbyshire, UK

“…Similarly, according to McGrath and Loveland [5], such strong correlations between EDTA Cu, Pb, Zn, Mn and their total concentrations were found in England and Wales with EDTA Ni fraction linked weakly with their total concentration. In addition, a strong positive correlation for Cu, Pb, Zn, and Mn is also reported by Hernandez and Pastor [30] in Sierra de Guadarrama in Spain for areas covering a former mine. However, a strong negative correlation was found for EDTA Cr fraction and its total concentration (Table 4).…”

A method for the integration of satellite vegetation activities observations and magnetic susceptibility measurements for monitoring heavy metals in soil

“…Despite the existence of many controlling factors for the spatial variability of soil magnetic susceptibility, magnetic measurements of soils have become reliable, efficient and sensitive [27,28]. The method is fast, non-destructive and complementary to conventional chemical analysis, allowing the exploration and investigation of extensive areas (regional, national, international areas) in short time periods [29][30][31][32][33][34].…”

Evaluation of semi-arid arable soil heavy metal pollution by magnetic susceptibility in the Linfen basin of China

“…The results disagree with those reported from other industrial and urban areas. Previous studies have reported v lf to be significantly correlated to integrated pollution index, Fe, Cu, and Zn (Lu et al 2008;Morton-Bermea et al 2009). The lack of a relationship between v lf and Zn in this case can be attributed to arable soils.…”

“…(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). It is thought that magnetic signals originating from soils or sediment might prove useful for reconstructing the development of the pollution history of the surrounding areas.…”
