摘　　要：沥青混合料运输过程中挥发性有机物(volatile organic compounds,VOCs)的排放具有影响区域广、排放量大等特点,给区域环境带来了负面影响。为探究沥青路面建设过程中运输阶段VOCs的排放特征、环境影响和健康风险,对沥青混合料运输阶段的VOCs排放进行了现场实测,并对VOCs排放总量、排放强度进行了估算。结果表明:沥青混合料的VOCs排放浓度在运输阶段具有一定的温度依赖性,运输阶段VOCs排放主要贡献组分为烷烃和醛类;2019年全国沥青路面建设运输阶段VOCs排放总量为45.54 t,排放强度为0.76 t/min;醛类和芳香烃组分分别是沥青混合料运输阶段臭氧和二次有机气溶胶生成的主要污染物;运输阶段VOCs排放存在较大的健康风险,丙烯醛、乙醛、甲醛和1,2-二氯甲烷是主要的致癌和非致癌危害物质。The transportation process of asphalt mixture during asphalt pavement construction is characterized by a broad impact area and substantial emissions of volatile organic compounds(VOCs),which have adverse effects on the regional environment.To investigate the emission patterns,environmental consequences,and health risks associated with VOCs during the transportation process of asphalt mixture in asphalt pavement construction,we conducted on-site measurements of VOCs emissions and estimated the total emissions and emission intensity during this phase.The findings are as follows:the emission concentration of asphalt-based materials during the transportation phase exhibits a certain temperature dependency,with alkanes and aldehydes constituting the primary contributors to VOCs emissions;in 2019,the nationwide total VOCs emissions during the transportation phase of asphalt pavement construction amounted to 45.54 t,with an emission intensity of 0.76 t/min;aldehydes and aromatic hydrocarbons are the predominant pollutants contributing to the ozone index and secondary organic aerosol index during this phase;notably,there is a significant health risk associated with VOCs emissions during the transportation phase,with acrolein,acetaldehyde,formaldehyde,and 1,2-dichloromethane identified as the primary carcinogenic and non-carcinogenic hazardous substances.
