| description | <p>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
<span class="inline-formula"><i>α</i></span>-Fe, as well as quartz, feldspar and pyroxene often attached to the
magnetic particles. The magnetic particles vary in size, from over 20 <span class="inline-formula">µm</span> 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.</p> |
