This paper reports on using low-cost, energy-efficient magnetic measurements to study pollution in the Lviv agglomeration, a major industrial and cultural centre of Western Ukraine. Soil magnetic properties were measured in two areas and along one transect. 66 surface topsoil samples were collected in the grid surveyed (a depth of 0–5 cm) at Jewish Park, 33 samples—along the transect. 15 soil samples were taken randomly from an area of Lychakiv Park to identify the magnetic properties of natural soil in the study area. The highest values of magnetic susceptibility (χ) were recorded in soil samples collected near roads with heavy traffic and the railway embankment area (150–237 × 10–8 m3/kg); At a distance of about 20–25 m from the road the χ values were 45–80 × 10–8 m3/kg. In the green space zones of Jewish Park, the Vysokyi Zamok castle, and the Lychakiv Cemetery, χ values displayed a significant decrease (12–24 × 10–8 m3/kg). The thermomagnetic analyses demonstrated a global maximum at 128 K, close to the Verwey transition and the isotropic point of magnetite. The hysteresis parameters suggest the presence of coarse-grained pseudo-single domain (PSD) and multidomain grains (MD) in the samples. The obtained results could be valuable in determining hotspots and pollution levels in the Lviv area using magnetic measurements of soil, as well as further precision geochemical studies.
