CEJUDO RUIZ, Fredy Rubén et al. Elemental composition and magnetic properties of urban soil of Guadalajara, Mexico. Rev. Int. Contam. Ambient [online]. 2025, vol.41, 55271.  Epub 25-Ago-2025. ISSN 0188-4999.  https://doi.org/10.20937/rica.55271.

The objective of this research was to identify the content of elements and magnetic properties of urban soil in the city of Guadalajara, in order to establish a reference concentration value that would enable the assessment of element enrichment in urban soil. Additionally, it aims to identify the magnetic parameters related to the concentration of elements, with the purpose of using them as indirect pollution monitors. The total background concentration values were obtained from 58 residential soil samples for chromium (Cr), copper (Cu), nickel (Ni), lead (Pb), vanadium (V), and zinc (Zn), with values of 13, 18, 10, 26, 36, and 269 mg/kg, respectively. The magnetic parameters of magnetic susceptibility and saturation isothermal remanent magnetization demonstrate a correlation with the concentration of elements, making them suitable for use as monitors of heavy metal accumulation and the identification of contaminated sites. The urban soils of Guadalajara exhibit a decreasing order of element content, with Zn > V > Pb > Cu > Cr > Ni. The highest concentrations of elements are observed in sites in the central and northwest regions of Guadalajara, particularly in densely populated areas, which pose a risk to the population that requires surveillance and further study.
