20.500.12556/DiRROS-15224 Attic dust: an archive of historical air contamination of the urban environment and potential hazard to health? A comprehensive study of attic dust in an urban area is presented. Its entire life cycle, from determining historical emission sources to recognising the processes that take place in attic dust and its potential to impact human health is discussed. Its chemical composition and morphological characteristics of individual solid particles reflect past anthropogenic activities. High levels of Be-Cd-Cu-Sb-Sn-Pb-Te-Zn and occurrence of Cu-Zn shavings are typical for an industrial zone characterised by a foundry and a battery factory. High levels of Co-Fe-Mo-Ni-W-Ba-Cr-Mg-Mn-Nb-Ti and occurrence of various solid Fe-oxides, particularly spherical particles, were identified in another industrial zone, which was dominated by the automotive and metal-processing industries. Emissions from coal combustion affected the distribution of S-Se-Hg-Tl-As-Ag-U. The predominant mineral in attic dust is gypsum, which was presumably formed in situ by the reaction of carbonate dust particles and atmospheric SO2 gas. The high oral bioaccessibility of As-Cd-Cu-Pb-Zn in the gastric phase and high bioaccessibility of As-Cu-Cd-Ni in the gastrointestinal phase were identified. Determined characteristics of attic dust and identified possibilities of prolonged human exposure to it indicate that attic dust should be treated as an excellent proxy for historical air contamination as well as a potentially hazardous material for human health. multi-element composition scanning electron microscopy oral bioaccessibility unified BARGE method urban geochemistry true false true Elsevier Angleški jezik Ni določen Delo ni kategorizirano 2022-06-23 09:08:54 2022-06-23 09:19:51 2022-08-21 03:36:08 0000-00-00 00:00:00 2022 0 0 14 str. vol. 432 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 504.5 0304-3894 10.1016/j.jhazmat.2022.128745 102046723 1-s2.0-S0304389422005349-main.pdf 1-s2.0-S0304389422005349-main.pdf 1 BE0E6CF9410BA1EE00E9A06D912E4005 b883aeb021cc408edc51de1238f66fa4a1d6fc79380a55c8e1d1c0bc2e8deacf f1be074c-17b6-11ed-b6b8-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=19964 Geološki zavod Slovenije 0 0 0
