This study aimed to characterize the impact of soda ash manufacturing on the magnetic properties of soils in north-central Poland. It found high magnetic anomalies of technogenic origin in the soils, and a statistically confirmed relationship between high magnetic susceptibility and the content of selected metals. Three potential factors influencing contaminant migration were identified, including highly saline ground and surface water, eolian transport of mineral fractions, and atmospheric deposition of coal combustion products.
The aim of this study was to characterize the impact of soda ash manufacturing on the magnetic properties of soils located in the agricultural landscape in north-central Poland. Two study sites were chosen: Matwy (SM) and Janikowo (SJ). Highly saline soils with halophyte communities were selected in order to develop an understanding of the relationship between salinization of water-soil interface and the potential contamination risk of the environment. Basic chemical and physicochemical properties of topsoil (0-25 cm) and water (surface and groundwater) samples from five locations were characterized. The characteristics of soil contamination were based on the content of selected metals, magnetic properties and salinity indices. Potential routes of contaminant migration (air and water fluxes) were analyzed. High magnetic anomalies of technogenic origin were revealed in the studied soils. A statistically confirmed relationship between high magnetic susceptibility and the content of selected metals (Co, Ni, Cu, Zn, Ba, Pb and Mn) showed the high utility of magnetometric techniques in soil research (diagnosis of soil transformation and contamination during technogenic impact). Three potential factors influencing contaminant migration were revealed: highly saline ground and surface water, eolian transport of fine-grained mineral fractions from waste ponds and atmospheric deposition of coal combustion products.
