Abstract：
An investigation was conducted into the dynamic behavior of two polyaromatic hydrocarbon (PAH) semi-volatile organic compound (SVOC) naphthalene (NAP) and benzo [ghi]perylene (BghiP) in air and on various surfaces including glass, dust, and polyurethane foam (PUF) to understand their interaction with different media. A confocal fluorescence microscope and an infrared microscope were employed to detect and monitor the concentration-, time-, and temperature-dependent changes of the aromatic NAP and BghiP species on the surfaces. Infrared two-dimensional mapping of the vibrational characteristic peaks was used to track the two PAHs on the surfaces. Gas chromatography-mass spectrometry (GC-MS) was employed to measure the gaseous concentrations. The sorption of NAP and BghiP on the surfaces was estimated using Arizona desert sand fine (ISO 12103-1 A2) dust and organic contaminant household (SRM 2585) dust. The surface-to-air partition coefficients of NAP and BghiP were estimated on the different surfaces of glass, dust, and PUF. Molecular dynamic simulations were performed on dust surfaces based on the Hatcher model to understand the behavior of NAP and BghiP on dust surfaces. The Weschler-Nazaroff model was introduced to predictPAH film accumulation on the surfaces, providing a better understanding of PAH interaction with different environmental media. These findings could contribute to developing effective strategies to mitigate the adverse impact of PAHs on the environment and human health.
摘要：
研究了两种多环芳烃（PAH）半挥发性有机化合物（SVOC）萘（NAP）和苯并[ghi]perylene（BghiP）在空气中以及包括玻璃在内的各种表面上的动态行为，灰尘,和聚氨酯泡沫（PUF）进行，以了解它们与不同介质的相互作用。采用共聚焦荧光显微镜和红外显微镜检测和监测浓度,time-,以及表面上芳族NAP和BghiP物种的温度依赖性变化。振动特征峰的红外二维映射用于跟踪表面上的两种PAH。使用气相色谱-质谱(GC-MS)来测量气体浓度。通过测试亚利桑那州沙漠细砂（ISO12103-1A2）和有机污染物家庭（SRM2585）粉尘，估算了NAP和BghiP在表面的吸附。在不同表面上估算了NAP和BghiP的表面-空气分配系数，包括玻璃,灰尘,PUF。基于Hatcher模型对粉尘表面进行了分子动力学模拟，以了解NAP和BghiP在粉尘表面上的行为。引入Weschler-Nazaroff模型来预测PAH膜在表面的积累，更好地了解他们与不同环境媒体的互动。这些发现可能有助于制定有效的策略，以减轻PAHs对环境和人类健康的不利影响。
