Abstract:Namen raziskave je bil analizirati število trdnih delcev, akumuliranih na mahu. Preučevali smo delce treh velikostnih razredov: 10 μm, 2,5 μm in 1 μm. V odvisnosti od velikosti delcev smo ovrednotili korelacijo s koncentracijo težkih kovin ter preučili prostorsko odvisnost števila delcev glede na oddaljenost od cestnega omrežja. Vzorčenje mahu smo izvedli po uveljavljenem protokolu iz literature. V laboratoriju smo vzorce najprej posušili, nato pa analizirali število delcev na 100 μm² površine lističev mahu z uporabo vrstičnega elektronskega mikroskopa (SEM). Analiza je temeljila na seriji posnetkov površine lističev, iz katerih smo na podlagi večkratnih meritev izračunali povprečne vrednosti ter ločeno obravnavali posamezne velikostne razrede delcev. Poleg tega smo v okviru eksperimentalnega dela izvedli analizo vsebnosti težkih kovin z metodo induktivno sklopljene plazme z masno spektrometrijo (ICP-MS). Zaradi morfoloških značilnosti lokacije vzorčenja pričakovani rezultati niso bili doseženi. Kljub temu smo izvedli korelacijsko analizo med koncentracijami težkih kovin in številom trdnih delcev, ki je pokazala zelo šibko povezavo, ne glede na velikost delcev. Prav tako je bila šibka tudi korelacija med številom delcev in oddaljenostjo od ceste.

Title:Analysis of dust particles on moss surface
Abstract:The aim of this study was to analyze the number of solid particles accumulated on moss. Three particle size classes were examined: 10 μm, 2.5 μm, and 1 μm. Depending on particle size, correlations with heavy metal concentrations were evaluated, and the spatial dependence of particle abundance on the distance from road networks was investigated. Moss sampling was carried out following an established protocol from the literature. In the laboratory, the samples were first dried and subsequently analyzed for the number of particles per 100 μm² of moss leaf surface using a scanning electron microscope (SEM). The analysis was based on a series of surface images, from which mean values were calculated across repeated measurements, with individual size classes considered separately. In addition, heavy metal content was determined using inductively coupled plasma mass spectrometry (ICP-MS). Due to the morphological characteristics of the sampling site, the expected results were not obtained. Nevertheless, correlation analysis between heavy metal concentrations and the number of PM particles revealed a very weak relationship, regardless of particle size. Similarly, the correlation between particle number and distance from the road was also weak, independent of particle size.
Keywords:heavy metals, PM particles, microplastics, ICP-MS, SEM
