摘要
为探究菏泽市大气醛酮类化合物污染特征,分析菏泽市2022年5—9月大气醛酮类化合物监测结果,计算臭氧生成潜势,同时利用相关系数法和比值法分析醛酮污染物可能来源。研究表明:菏泽市大气主要的醛酮类化合物为甲醛、乙醛和丙酮;臭氧生成潜势贡献较大的主要是甲醛和乙醛;菏泽市大气醛酮类化合物中甲醛、乙醛、丙酮有强相关性,三者可能有相同来源,其中甲醛和乙醛浓度比为1.07,符合城市大气特征,即主要受人为源的影响。
In order to investigate the pollution characteristics of aldehydes and ketones in Heze city,the monitoring results of aldehydes and ketones in Heze from May to September 2022 were analyzed,the ozone formation potential(OFP)was calculated,and the possible sources of aldehydes and ketones were analyzed by correlation coefficient method and ratio method.The results showed that formaldehyde,acetaldehyde and acetone were the predominant aldehydes and ketones in the atmosphere of Heze.Formaldehyde and acetaldehyde contributed more to ozone formation potential.Formaldehyde,acetaldehyde and acetone in the atmosphere of Heze had strong correlation,which may have the same source.The concentration ratio of formaldehyde to acetaldehyde is 1.07,which accorded with the characteristics of urban atmosphere and was mainly affected by the human source.
