Observed data at 12 air-quality monitoring stations in urban Beijing in 2013 were analyzed for investigating the weekend effect of air pollutants and the reasons of weekend effect of O3. Diurnal variation of SO2 showed a single-peak curve with the peak at 11:00. Average hourly concentrations of SO2 in weekends were higher than those on weekdays, with a daily average deviation of 15.57%. Diurnal variation of NO2 showed a bimodal curve with the peaks at 08:00 and 22:00. Average hourly concentrations of NO2 from 00:00 to 18:00 were higher in weekends than those on weekdays, with a daily average deviation of 7.50%. Diurnal variations of PM10 and PM2.5 showed bimodal curves on weekdays, while showed wave-shape curves in weekends. Average hourly concentrations of PM10 and PM2.5 in weekends were higher than those on weekdays with daily average deviations of 17.84% and 20.22%, respectively. Diurnal variation of O3 in urban Beijing showed a single-peak curve with the peak at 16:00. Concentrations of O3 from 11:00 to 24:00 were higher in weekends than those on weekdays, and concentrations of its precursors in weekends were higher than or close to those on weekdays. One possible reason was that the inhibition of NO on O3 was weaker in weekends than that on weekdays in the O3 suppression stage, which was favorable for the formation of O3. The second reason was that concentration of CO in weekends was higher than that on weekdays, which promoted the formation of O3 and led to weekend effect of O3.
