Abstract
Troposferski ozon je sekundarni polutant koji nastaje fotokemijskim reakcijama u nižim dijelovima Zemljine troposfere. Za nastanak ozona bitni su prekursori iz kojih on nastaje; dušikovi oksidi i hlapljivi ugljikovodici, dok ugljikov(II) oksid posredno sudjeluje u produkciji ozona. Prekursori ozona se emitiraju s površine Zemlje u atmosferu, a glavni su im izvor u gradu Osijeku promet i industrijski procesi. U ovom završnom radu prikazani su i analizirani rezultati mjerenja koncentracije ozona, benzena, dušikovih oksida i ugljikovog(II) oksida za 2018. i 2019. godinu. Mjerna postaja se nalazi u gradu Osijeku i pomoću automatskog analizatora mjeri koncentraciju pojedinih zračnih polutanata. Grafičkom analizom prikazan je dnevni hod ozona s karakterističnim podnevnim maksimumom i jutarnjim minimumom. Izradom polarnih dijagrama može se utvrditi povezanost koncentracije ozona, benzena, dušikovih oksida i ugljikovog(II) oksida sa smjerom vjetra. Izračunom koeficijenta korelacije i analizom glavnih komponenata utvrđena je korelacija između prosječnih dnevnih vrijednosti koncentracije polutanta i prosječnih dnevnih vrijednosti meteoroloških parametara.
Abstract (english)
The tropospheric ozone is a secondary pollutant formed by photochemical reactions in the lower parts of the Earth's troposphere. The precursors from which ozone is formed are essential for the formation of ozone; nitrogen oxides and volatile organic compounds, while carbon monoxide indirectly participates in ozone production. Ozone precursors are emitted from the Earth's surface into the atmosphere and the main source of ozone precursors in the city of Osijek are traffic and industrial processes. The measuring results of the concentration of ozone, benzene, nitrogen oxides and carbon monoxide for 2018 and 2019 are presented and analyzed in this paper. The measuring station is located in the city of Osijek and uses an automatic analyzer to measure the concentration of individual air pollutants. The graphic analysis shows the average diurnal distribution ozone with a characteristic noon maximum and morning minimum. The correlation of the concentration of ozone, benzene, nitrogen oxides and carbon monoxide with the wind direction can be determined by making polar diagrams. By calculating the correlation coefficient and principal component analysis, the correlation between the average daily values of the pollutant concentration and the average daily values of meteorological parameters were determined.
