“…Modeling studies attribute tens of percentages of present day net aerosol cooling effects over industrial regions to SOA generated from biogenic and anthropogenic VOC precursors, like those emitted during asphalt applications. 86,107 As temperatures increase as a result of climate change feedback, changes in biogenic emissions may further enhance the formation of anthropogenic aerosols from asphalt sources and their cumulative climate impacts. 12 Considering the widespread usage of asphalt materials in pavements, roofs, and infrastructure, life cycle analyses demonstrate the sizable carbon footprint ranks among the largest industrial sectors.…”

The emission of volatile organic compounds (VOCs) from asphalt during construction processes presents substantial risks to human health and the environment. To advance sustainable transportation development, this review offers a comprehensive study of the methods for characterization, release characteristics, influencing factors, release mechanisms, and environmental impacts of asphalt VOCs. At present, research has been conducted on characterization methods, component characteristics, influencing factors, and environmental and health risks. The findings indicate that gas chromatography–mass spectrometry is the most comprehensive method for characterizing asphalt VOCs. Asphalt VOCs mainly comprise alkanes, aromatics, and aliphatic hydrocarbons. Factors including the temperature, asphalt source, and ultraviolet radiation can all affect the release characteristics of asphalt VOCs. Elevated VOC levels contribute to the photochemical production of ozone and fine particulate matter, exacerbating air pollution and climate change. Additionally, specific asphalt VOCs, including benzene and polycyclic aromatic hydrocarbons, pose health risks to humans. While progress has been achieved in the current research, challenges persist in quantifying VOCs, assessing their environmental impacts and health risks, and implementing effective mitigation technologies. To address these challenges, future research should focus on establishing asphalt VOC fingerprints, quantitative methods, evaluation criteria, material innovation, optimization of construction processes, exposure assessment, and collaborative solution implementation.

“…Recently, the higher alkanes (≥ C8), one kind of considerable species in residential combustion emissions Huo et al, 2021b;Li et al, 2023), which were not included in the comprehensive measurements of previous studies (Hatch et al, 2017), could be measured well by PTR-ToF-MS with NO + ion chemistry (C. Koss et al, 2016). Thus, PTR-ToF-MS might be a preferential and promising method for the development of near-complete ROG speciation relevant for residential combustion, but it needs to be combined with GC-MS/FID for the complementary measurement of aliphatic hydrocarbons.…”

Abstract. Reactive organic gases (ROGs), as important precursors of secondary pollutants, are not well resolved as their chemical complexity has challenged their quantification in many studies. Here, a near-complete speciation of ROG emissions from residential combustion was developed by the combination of proton transfer reaction time-of-flight mass spectrometry (PTR-ToF-MS) with a gas chromatography system equipped with a mass spectrometer and a flame ionization detector (GC-MS/FID), including 1049 species in all. Among them, 125 identified species, ∼ 90 % of the total ROG masses, were applied to evaluate their emission characteristics through real combustion samplings in rural households of China. The study revealed that with 55 species, mainly oxygenated species, higher hydrocarbons with ≥8 carbon atoms, and nitrogen-containing species, previously un- and under-characterized, ROG emissions from residential coal and biomass combustion were underestimated by 44.3 % ± 11.8 % and 22.7 % ± 3.9 %, respectively, which further amplified the underestimation of secondary organic aerosol formation potential (SOAP) as high as 70.3 % ± 1.6 % and 89.2 % ± 1.0 %, respectively. The hydroxyl radical reactivity (OHR) of ROG emissions was also undervalued significantly. The study provided a feasible method for the near-complete speciation of ROGs in the atmosphere and highlighted the importance of acquiring completely speciated measurement of ROGs from residential emissions, as well as other processes.
