Abstrakt: This study aims to investigate the presence, sources and transport of metallic elements in atmospheric aerosols, with a particular emphasis\non temporal (seasonal and diurnal) variability of metals in particulate matter (PM) and identify their emission sources. The cuttingedge X-ray fluorescence (XRF) spectroscopy (Cooper Environmental Xact 625i, ElvaX PMX) will be utilized for near real-time metal analysis with superior time resolution and simultaneous multi-element detection, which facilitates the examination of swift changes in metal levels and enhances source apportionment. The measurements will take place at a rural background site, National Atmospheric Observatory Košetice and an urban background site at Suchdol, Prague, Czech Republic. By integrating XRF and meteorological data, we aim to understand the physico-chemical properties and atmospheric behaviour of metal-containing aerosols and improve knowledge of their sources.
