Abstract
This study observed the concentration of secondary photochemical air pollutants in Tucheng, cooperate with various kinds of factor, to confer the variation tendencies of secondary photochemical pollutants and ozone. It was also use box model with case simulation, to discuss the main contribution species during high ozone period.
Analyze the concentration of secondary photochemical air pollutants in Tucheng from June of 2006 to May of 2007, its daily and seasonal variation tendency. In this research observe period, find it is roughly the same as ozone daily tendency that H2O2 and carbonyl. In this study, the seasonal variation tendency of ozone is influenced by the wind direction, in sample period at prevailing wind direction east wind, ozone does not have obvious seasonal variation tendency, the concentration of carbonyl were falls within the specific limits at this moment; When the prevailing wind direction is west wind, ozone has seasonal variation tendency at this moment, it is also roughly the same with H2O2 and Carbonyl.
May 3, 2007 is ozone episode, this research regards this as the case, analyzed the concentration of ozone changes the origin cause of formation. By various kinds of factor analysis, wind direction was probably influence factor.
This research regards May 3, 2007 as the case of studying through the photochemistry box model. The variation tendency of ozone in the daytime of simulation, analyze its main sensitiveness species. Find through simulation, change in initial stage when case type way can really imitate the concentration of ozone.Compare with paraffins、oleffins、atomatics and carbonyl,the sensitiveness species is aromatics and carbonyl as the main contribution species causing the ozone in this research case.
