“…Our Mössbauer spectroscopy results indicate that Fe-bearing particles in the aerosols are very small, showing a superparamagnetic behaviour at room temperature (RT) and becoming ferromagnetic while lowering the measurement temperature. On one hand, the possibility of superparamagnetic particles being present in the suspended particulate matter was dismissed by some authors on the basis of the magnetization measurements (Magiera et al, 2021). On the other hand, the possibility of the long-range transportation of tiny (a few nanometres to a few tenths of a nanometre in diameter) particles far from the industrial sources cannot be eliminated.…”

Abstract. It is well established that airborne, magnetic nano- and microparticles accumulate in human organs (e.g. brain) thereby increasing the risk of various diseases (e.g. cancer, neurodegenerative diseases). Therefore, precise characterization of the material, including its origins, is a key factor in preventing further, uncontrolled emission and circulation. The magnetic fraction of atmospheric dust was collected in Kraków using a static sampler and analysed using several methods (scanning electron microscopy with energy-dispersive spectrometry, transmission electron microscopy with energy-dispersive spectrometry, X-ray diffraction, Mössbauer spectroscopy, and vibrating sample magnetometry (VSM) measurements). The magnetic fraction contains magnetite, hematite and α-Fe, as well as quartz, feldspar and pyroxene often attached to the magnetic particles. The magnetic particles vary in size, from over 20 µm to nanoparticles below 100 nm, as well as in morphology (irregular or spherical). Their chemical composition is dominated by Fe, often with Mn, Zn, Cr, Cu, Si, Al, S, Ca and other elements. Mössbauer spectroscopy corroborates the composition of the material, giving further indications of particles smaller than 100 nm present in the atmospheric dust. VSM measurements confirm that the strength of the magnetic signal can be treated as a measure of the anthropogenic impact on the suspended particulate matter, once again highlighting the presence of nanoparticles.

“…Recent studies claim dust samples from the iron and non-ferrous metallurgy differ in terms of magnetic susceptibility as well as their mineral and chemical composition (Jablonska et al 2021, Szumiata et al 2017). Technogenic magnetic particles are reported to be indicative for industrial pollution sources (Magiera et al 2021; Shen et al 2013; Szuszkiewicz et al 2015). Magnetic measurements combined with thermomagnetic analyses were found to be a useful tool for interpreting the origin and nature of minerals to determine the man-made impact (Jordanova et al 2003;Szuszkiewicz et al 2016).…”

Metallurgical industries incorporated into the living environment of the city cause significant enrichment of the topsoil with harmful substances including small size particulate matter, which contains heavy metals and magnetic iron oxides. The present study is focused on characterization of magnetic and geochemical pollution accumulated by urban soils in the city of Zaporizhzhia. Industrial dusts from the most powerful emmitants of airborne pollution are also analyzed. Two types of magnetic industrial emissions were discriminated to contribute in urban soil magnetization: spread of coarse-grained magnetite-bearing particles is limited to industrial zone, while smaller magnetic spherules were traced to settle far from the pollution sources bringing significant amounts of heavy metals to the soil. Magnetic susceptibility, saturation remanence and anhysteretic ratio of soil samples show strong relationship with heavy metals contents and Pollution Load Index. Thus magnetic parameters can serve as reliable proxies for complex urban and industrial pollution of soils. The obtained results provide important insight into magnetism and geochemistry of urban soils in Zaporizhzhia, characterizing the pollution rate as it was before missile attacks, aerial bombardments and artillery shelling of the city by russian invaders started since 24 February 2022.
