摘　　要：为探究沥青路面铺设对大气环境VOCs的影响,于2022年12月在河北省邯郸市典型沥青路面铺设过程进行VOCs采样,并进行其排放特征和环境影响研究。结果表明:沥青路面铺筑过程中VOCs排放以OVOCs和烷烃组分为主,甲醛是沥青路面铺筑过程中的首要污染物;沥青路面摊铺阶段VOCs排放对沥青路面铺筑过程中O_(3)和PM_(2.5)生成贡献最大;OVOCs是沥青路面铺筑O_(3)生成的主要贡献组分,芳香烃和烷烃是沥青路面铺筑PM_(2.5)生成的主要贡献组分;控制好甲醛、乙醛、丙醛、间二甲苯、对二甲苯、间乙基甲苯、十一烷、十二烷和癸烷等VOCs物质是沥青路面铺筑过程O_(3)和PM_(2.5)控制的关键。To investigate the impact of asphalt pavement laying on atmospheric volatile organic compounds(VOCs),VOCs sampling was conducted during the typical asphalt pavement laying process in December 2022 in Handan City,Hebei Province,China.The emission characteristics and environmental effects are studied.The results indicate that during the asphalt pavement laying process,VOCs emissions are primarily composed of oxygenated VOCs(OVOCs)and alkanes,with formaldehyde being the primary pollutant.During the asphalt pavement spreading stage,VOCs emissions contribute most significantly to the generation of O:and PM2.5.OVOCs are the major contributing components to O;generation during asphalt pavement laying,while aromatic hydrocarbons and alkanes are the major contributors to PM2.s generation.Controlling VOCs such as formaldehyde,acetaldehyde,propionaldehyde,m-xylene,p-xylene,o-ethyltoluene,undecane,dodecane,and decane is crucial for controlling O;and PM2.5 during the asphalt pavement laying process.
