摘要: Observations of ground-level ozone (O3), nitric oxide (NO), nitrogen dioxide (NO2), particulate matter (PM10) and meteorological parameter (temperature, relative humidity wind speed) fluctuations during high event (HPE) non-HPE in Malaysia have been conducted for 2 years (2013 2014). The study focuses on urban areas, namely, Shah Alam, Petaling Jaya Bandaraya Melaka. diurnal variations O3 concentration were higher HPE than those all areas. fluctuated more 2014 2013 due to the incidences HPE. Temperature speed with PM10, NO2 NO concentrations sites. Relative was lower that non-HPE. Positive correlations found between PM10 Alam 0.81 0.79, respectively. Meanwhile, negative correlation (− 0.76) recorded showed values locations except (0.02). shows a strong positive highest at (0.97). Inverse relationships O3, which (− 0.96) (− 0.97) Melaka 2014. result best-fit equation obtained an R2 0.6730. parameters had significant relationship predictions
