Abstract:
Introduction: Ozone (O3
) is a significant component of photochemical smog as a typical secondary which is formed
via nitrogen oxide photochemical interactions with volatile organic compounds (VOCs). This research discerns the
complex influence of meteorological parameters and air pollutants influencing O3
concentrations. Methods: Data
were acquired from 1 January 2018 until 31 December 2020 that including ozone (O3
), nitrogen oxide (NOx), nitric
oxide (NO), sulphur dioxide (SO2
), nitrogen dioxide (NO2
), carbon monoxide (CO), particulate matter (PM10, PM2.5),
wind speed, solar radiation, temperature, and relative humidity (RH). Data were analysed using descriptive statistics
in terms of line graphs. Results: The results demonstrate that the O3
concentration peaked around 14:00 hours and
dropped at night (20:00 hours) owing to the lack of sunshine and redox processes. Conclusion: In conclusion, ozone
precursors played an important role in ozone formation and the findings of this research are valuable for policymakers and other interested parties
