Abstract:Onesnažen zrak je eden najbolj perečih problemov sodobnega časa, zato je kontrola koncentracije onesnažil ključna za doseganje želene kvalitete življenja. Nadzor kakovosti zraka v Sloveniji opravlja Javna agencija Republike Slovenije za okolje (ARSO) in podatke redno objavlja na svoji spletni strani. Namen diplomske naloge je bil primerjati vrednosti onesnažil PM10 in PM2,5 v zraku v določenem časovnem obdobju. Analiza je bila izvedena na podlagi javno dostopnih podatkov na dveh merilnih mestih v Sloveniji, ki se razlikujeta po gostoti poselitve, reliefu in meteoroloških parametrih. Prvo merilno mesto je bilo prometno in urbano središče, drugo pa se je nahajalo v bližini večjega termoenergetskega objekta. Ugotovljeno je bilo, da se onesnaženost zraka s PM10 in PM2,5 tekom let zmanjšuje in da je onesnaženost s PM10 in PM2,5 večja na merilnem mestu z večjo gostoto poselitve, večjo količino prometa in manj ugodnim reliefom, ki otežuje izločanje onesnažil iz ozračja. Poleg tega je bila koncentracija delcev na obeh merilnih mestih najvišja pozimi, zaradi uporabe kurilnih peči v gospodinjstvih, ki so glavni vir izpustov, in najnižja poleti. Pandemija COVID-19 na zmanjšanje emisij delcev ni imela večjega vpliva. Nazadnje je bila izvedena še SEM-EDS analiza filtrov. Najpogosteje zastopani elementi na obeh merilnih mestih so bili ogljik, kisik in silicij, pri čemer je bila koncentracija ogljika na prvem merilnem mestu več kot dvakrat večja, najbrž zaradi večje količine izpustov iz prometa. Ostali elementi so bili na obeh merilnih mestih zastopani v približno enakem razmerju in jih gre predpisati različnim naravnim in antropogenim procesom.

Title:Analysis of air pollution with PM particles (PM10 and PM2.5) in Slovenia during the period between 2019 and 2022
Abstract:Polluted air is one of the most pressing issues of modern times, making the control of pollutant concentrations crucial for achieving a desired quality of life. Air quality monitoring in Slovenia is conducted by the Slovenian Environment Agency (ARSO), which regularly publishes data on its website. The aim of this thesis was to compare the levels of pollutants PM10 and PM2,5 in the air over a specific time period. The analysis was carried out based on publicly available data from two monitoring stations in Slovenia, which differ in population density, topography, and meteorological parameters. The first monitoring station was located in a traffic-heavy urban center, while the second was situated near a large thermal power facility. It was found that air pollution by PM10 and PM2,5 has decreased over the years, and that pollution levels of PM10 and PM2,5 were higher at the monitoring station with higher population density, more traffic, and less favorable topography, which hinders the dispersal of pollutants from the atmosphere. Additionally, particle concentrations at both monitoring stations were highest in winter due to the use of household heating systems, which are the main source of emissions, and lowest in summer. The COVID-19 pandemic did not have a major impact on the reduction of particle emissions. Lastly, an SEM-EDS analysis of the filters was conducted. The most commonly detected elements at both monitoring sites were carbon, oxygen, and silicon, with the concentration of carbon at the first monitoring site being more than twice as high, likely due to higher emissions from traffic. The other elements were present in approximately the same proportions at both monitoring sites and can be attributed to various natural and anthropogenic processes.
