摘要

本文采用室内实验和城市尺度空气质量模型相结合的方法,评价了沥青路面排放对城市空气质量的影响。特别是在大气模拟室内,测定了沥青路面挥发性和中间挥发性有机化合物(VOCs和IVOCs)的排放因子(EFs)。相对湿度(RH)和模拟太阳光UV-A辐射对VOCs和IVOCs的排放起关键作用。由于材料的微物理性质发生了变化,RH显著增加了电场,主要是含氧voc的电场。在UV-A辐射下,沥青-空气界面上产生的光化学反应增强了电场效应。研究发现,有机挥发性有机化合物占测量到的总EFs的30%。以巴黎为例,在空气质量模拟中,沥青排放导致有机气溶胶浓度在夏季平均白天条件下至少增加3%。如果所有的IVOCs排放都包含在模型中,我们估计这种影响要高得多。这突出了太阳辐射对暴露在紫外线辐射下的旧沥青排放的重大影响以及对夏季空气质量的影响。

Real-World Asphalt Pavement Emissions: Combining Simulation Chamber Measurements and City Scale Modeling to Elucidate the Impacts on Air Quality

Real-World Asphalt Pavement Emissions: Combining Simulation Chamber Measurements and City Scale Modeling to Elucidate the Impacts on Air Quality

In this paper, the role of asphalt pavement emissions in urban air quality was assessed combining laboratory experiments and city-scale air-quality modeling. In particular, the emission factors (EFs) of volatile and intermediate volatility organic compounds (VOCs and IVOCs) of asphalt pavements were determined in an atmospheric simulation chamber. Relative humidity (RH) and simulated solar light UV-A radiation were found to play a key role in the emission of VOCs and IVOCs. RH significantly increased the EFs, and predominantly those of oxygenated VOCs, due to changes in the microphysical properties of the materials. Under UV-A radiation, EFs were enhanced, due to the photochemical process induced on the asphalt–air interface. IVOCs were found to account for up to 30% of the Total EFs measured. Considering Paris as a case study, asphalt emissions in air-quality simulations lead to an increase in organic aerosol concentrations of at least 3%, during average summer daytime conditions. We estimate this impact significantly higher, in case all the IVOCs emissions are included in the model. This highlights the significant influence of solar radiation on emissions from old asphalt when exposed to UV radiation and the impact on air quality during the summer.
