Abstract

By extracting the diurnal variation trend, the air pollutant monitoring data series (such as the one-hour average for many years) are averaged by arithmetic at 24 hours per day, and the impact of air pollution sources on the environmental air quality in Tianhe District of Guangzhou is analyzed. The results show that the environmental air quality monitoring factors of each station are affected by moving sources in different periods, especially heavy vehicles. At the same time, some stations are affected by natural vegetation.
