福建省大气中CO污染特征研究

AbstractCarbon monoxide (CO)is an important gas in the global carbon cycle and one ofthe main pollutants in the atmosphere.In view of the current atmospheric pollutionproblems,Fujian Province was taken as the research object to conduct acomprehensive analysis of CO in Fujian Province's air pollutants from 2015 to 2019.The analysis results show that CO exhibits obvious monthly variation characteristics.On the whole level,the peak generally appears in January or December,and thevalley of CO mass concentration is from June to August;it is higher in spring andwinter,and lower in summer and autumn.Seasonal characteristics,in addition,theinterannual change trend,the characteristics of spatial change and the factors affectingthe Co concentration were also analyzed.This study can provide a morecomprehensive and objective reflection of the CO pollution situation in our province,and is of great significance for the monitoring and prediction of CO pollution.At thesame time,it can provide a reference for future air pollution prevention and control inFujian Province.Key words:air pollution;CO;pollution characteristics;influencing factors
