摘要

在建筑加热过程中，沥青会释放大量排放物，对工人和环境构成威胁。沥青排放的采样和分析方法多种多样。然而，沥青排放的量化结果受到多种因素的影响，目前还没有得到很好的研究。为了填补这一空白，在不同条件下收集的沥青排放样品在二硫化碳中溶解并分析。采用气相色谱-质谱联用技术（GC-MS）对橡胶屑改性沥青（CRMA）和基础沥青中的多环芳烃（PAHs）、苯和苯并噻唑等污染物进行了定量分析。根据不同影响因素下的定量结果，推荐了沥青排放的采样方法。沥青排放样品的尖刺回收率令人满意，表明试验结果的可靠性。在不同的实验条件下，排放率具有可比性。该方法可用于进一步的沥青减排研究，为支持空气质量改善工作提供可靠的数据。

Investigation of influence factors for sampling and quantification of organic emissions released from paving asphalt

During construction heating, asphalt releases significant emissions, posing risks to workers and the environment. There are various methods for sampling and analyzing asphalt emissions. However, the quantification results of asphalt emissions are affected by various factors, which is not well investigated. To fill this gap, asphalt emission samples collected under different conditions were dissolved in carbon disulfide and analyzed. Emissions, including polycyclic aromatic hydrocarbons (PAHs), benzenes, and benzothiazoles from crumb rubber modified asphalt (CRMA) and base asphalt, were quantified using gas chromatography-mass spectrometry (GC–MS). Based on the quantitative results under different influencing factors, a sampling procedure for asphalt emissions is recommended. The satisfactory spiked recovery rate of asphalt emission samples indicates the reliability of experimental results. Emission rates were comparable under different experimental conditions. This method can be used for further asphalt emissions reduction research, providing reliable data to support air quality improvement efforts.

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
