摘　　要：于2018年11月—2019年1月采集了青岛、烟台、日照、威海、潍坊、东营和滨州7个沿海城市的环境空气样品,分析了117种VOCs的污染水平、臭氧(O_(3))生成潜势、二次有机气溶胶(SOA)生成潜势。结果显示,观测期间,7个沿海城市大气VOCs质量浓度表现为东营(422μg/m^(3))>滨州(366μg/m^(3))>烟台(324μg/m^(3))>青岛(261μg/m^(3))>威海(226μg/m^(3))>潍坊(192μg/m^(3))>日照(146μg/m^(3))。其中,青岛、烟台、日照和东营以卤代烃为主要VOCs污染物,威海、潍坊和滨州以烷烃为主要VOCs污染物。滨州O_(3)生成潜势和SOA生成潜势最大,分别为872μg/m^(3)和0.70μg/m^(3);日照O_(3)生成潜势最小,为220μg/m^(3);东营SOA生成潜势最小,为0.22μg/m^(3)。芳香烃是7个城市SOA的重要前体物。Air pollutants were collected in Qingdao,Yantai,Rizhao,Weihai,Weifang,Dongying and Binzhou of Shandong Province during November 2018 to January 2019,and the pollution levels,ozone(O_(3))formation potential,secondary organic aerosol(SOA)formation potential of 117 kinds of VOCs were analyzed by preconcentration-gas chromatography/mass spectrometry and high performance liquid chromatography.The results showed that concentrations of air VOCs varied significantly with the seven coastal cities,with Dongying(422μg/m^(3))>Binzhou(366μg/m^(3))>Yantai(324μg/m^(3))>Qingdao(261μg/m^(3))>Weihai(226μg/m^(3))>Weifang(192μg/m^(3))>Rizhao(146μg/m^(3)).Among them,the main VOCs pollutants in Qingdao,Yantai,Rizhao and Dongying were halogenated hydrocarbons,and alkane were the main VOCs pollutants in Weihai,Weifang and Binzhou.The O_(3)formation potential and SOA formation potential of Binzhou were the highest,which were 872μg/m^(3)and 0.70μg/m^(3),respectively.The O_(3)formation potential was the smallest in Rizhao,which was 220μg/m^(3).And Dongying had the lowest SOA formation potential,which was 0.22μg/m^(3).Aromatic hydrocarbons were important precursors of SOA in seven cities.
