摘　　要：醛酮化合物是大气中的一类有机污染物,在黄河三角洲地区对其进行观测,可为控制该地区大气光化学污染,制定有效控制策略提供理论支持。文章研究了黄河三角洲地区中心城市——滨州市大气中醛酮化合物的污染特征,分别于2018年8月与2020年7月—8月采用EPA TO-11A方法外场观测研究了滨州市城区大气中醛酮化合物。结果表明:滨州市城区大气主要的醛酮化合物为甲醛、乙醛和丙酮;两次观测期的醛酮化合物日变化趋势均具有明显的早晚高峰;该地大气醛酮化合物受到人为源与自然源的共同影响,乙醛、丙醛和丁醛三者相关性较好,可能具有相同的来源;甲醛是观测期间LOH与OFP的主要优势醛酮物种,其他醛酮的贡献很小,对甲醛和乙醛的健康风险评价表明长期暴露在该醛酮化合物污染水平的环境空气中会对人体健康产生一定影响。Aldehydes and ketones are organic pollutants in the atmosphere.The observation of them in the Yellow River Delta can provide theoretical support for the control of atmospheric photochemical pollution in this region and the formulation of effective control strategies.In this paper,we investigated the pollution characteristics of atmospheric carbonyl compounds in the atmosphere of Binzhou City,the central city of Yellow River Delta,by using EPA TO-11A method in August 2018 and July-August 2020.The results showed that the main atmospheric carbonyl compounds in Binzhou are formaldehyde,acetaldehyde and acetone.The diurnal variation characteristics of carbonyl compounds during these two observation periods both showed obvious morning and evening peaks.The carbonyl compounds was affected by both anthropogenic and natural pollution sources.Acetaldehyde,propionaldehyde and butyraldehyde had good correlations with each other and may have similar sources.For LOH andOFP,formaldehyde was the main carbonyl species during the observation periods,and while the contributions of other carbonyls were small.The health risk assessment of formaldehyde and acetaldehyde indicated that long-term exposure to ambient air at such concentrations have adverse effects on human health.
