“…Other studies have focused on magnetic properties of indoor dust as a potential indicator of indoor air quality (Górka-Kostrubiec et al 2014; Górka-Kostrubiec 2015; Szczepaniak-Wnuk and Górka-Kostrubiec 2016). …”

“…Górka-Kostrubiec et al (2014) determined the magnetic characteristics, e.g., mineralogy, grain size, and domain structure, of indoor dust collected from flats and houses in Warsaw, Poland. The histogram of magnetic susceptibility revealed an asymmetric tendency with significant deviation from the normal distribution due to a group of the samples having significantly higher values of magnetic susceptibility.…”

“…In this work, we examined the coexistence of magnetite with metallic iron in indoor dust using the same sets of samples as in Górka-Kostrubiec et al (2014) and Szczepaniak-Wnuk and Górka-Kostrubiec (2016). Our attention focused on determining the magnetic properties of the magnetite + Fe mixture and those of its thermal product, i.e., after a heating-cooling cycle.…”

Magnetite in mixture with metallic iron in indoor dust samples was examined using several magnetic analyses, thermomagnetic curves of the magnetic susceptibility and the induced magnetization vs. temperature, hysteresis loops, and first-order reversal curves. The study of the magnetic properties was supplemented by the analysis of chemical elements and electron microscopic observation. The metallic iron in the mixture affects the values of hysteresis parameters, decreasing coercivity (B c) and increasing saturation magnetization (M s), and it is responsible for the magnetic enhancement of magnetic susceptibility. The thermomagnetic curves show several distinct features: the first Curie temperature of magnetite, the second one (∼764 °C) of iron, and the rapid decrease on the heating curves (between 600 and 750 °C) caused by the oxidation of iron to magnetite. Two magnetochemical processes appear during the thermal treatment of indoor dust: the oxidation of iron to magnetite and the neo-formation of magnetite as a result of chemical transformation of non-magnetic minerals. The shift of the hysteresis parameter ratios from the multi-domain (MD) region towards the single-domain (SD) region on the Day-Dunlop plot is controlled by the oxidation of iron in the thermally induced process and the grain size of the new formed magnetite. The magnetic properties of indoor dust are a potential indicator of indoor air pollution. Elemental iron plays an important role in the development of inflammation in humans via oxidative stress, so that the presence of metallic Fe in indoor dust can affect human health.

“…If the dust does not have specific biological effects and acts just dusty lungs, we are talking about dust biologically inert. Metallic dust is serious and its study is the subject of much research [4], [5] and conjecture of environmental activists [3]. The major source of dust particles in indoor with outdoor pollution which it penetrated inside the mechanical and natural ventilation systems (air proximity), and the Activities of people (soil proximity).…”

Particles larger than 100 microns have relatively little medical significance, because thanks to their considerable weight they quickly settle.…”

The paper describes the importance of monitoring the dust in the atmosphere of human life. It deals with the issue of dust in air ducts, approaching the methods that can be used to detect the amount of dust. For conditions for buildings in the Czech Republic there is created the methodology of quantitative and qualitative evaluation of dust sediment for the needs of HVAC and other building surfaces. The scale for visual evaluation was created and it has been elaborated the assessment of kind of particles contained in dust.
