Abstract
This study focused on O3 variations and the titration effects of NOx during nighttime at urban, industrial, sub-urban and background sites. Nighttime O3 concentration variations and the presence of high particles with an aerodynamic diameter of less than 10 μm (PM10) were examined because haze disturbs the photochemical reactions of O3. Hourly data on O3, NO2, NO and PM10 concentrations provided by the Air Quality Division of the Department of Environment were divided into two groups of daytime and nighttime and analysed.
