亚特兰大通勤者暴露（ACE）研究旨在测量一组有哮喘和无哮喘的成年人在亚特兰大主要高速公路上遵循2小时的既定路线的车内暴露于道路颗粒污染和急性健康反应。本文重点介绍了用于测量PM2.5质量、颗粒数浓度（PNC）、黑碳（BC）质量和颗粒结合的多环芳烃浓度、舱内噪声、PM元素组成、元素碳、有机碳、水溶性有机碳（WSOC）含量以及烷烃、藿烷和多环芳烃等多种有机化合物形态的连续方法和综合方法的方法和结果。指定的PM数据表明，车内颗粒来源于三个非共变过程：含有地壳元素和先前沉积的刹车片残留物的道路尘埃的再悬浮（有正常燃料燃烧的作用），产生多环芳烃和碳颗粒的不完全燃烧过程，以及先前未沉积到路边环境的刹车片烧蚀的颗粒。暖季期间，除PNC外，大部分舱内污染物升高。没有发现PNC与大多数其他污染物相关。当窗户打开时，舱内的浓度略高。
The Atlanta Commuters Exposure (ACE) Study was designed to measure in-cabin exposure to roadway particulate pollution and acute health response in a panel of adults with and without asthma following a 2-h scripted route along major highways in Atlanta. This article focuses on methods and results of both continuous and integrated approaches used to measure the concentration of PM2.5 mass, particle number concentration (PNC), black carbon (BC) mass, and particle-bound PAHs, in-cabin noise, PM elemental composition, elemental carbon, organic carbon, water-soluble organic carbon (WSOC) content, and speciation of a broad range of organic compounds including alkanes, hopanes, and PAHs. Speciated PM data indicates that in-cabin particles derive from three non-co-varying processes: the resuspension of road dust containing crustal elements and previously-deposited brake pad residue with a contribution of normal fuel combustion, incomplete combustion processes producing PAHs and carbon particles, and particles ablated from brake pads that have not previously deposited to the roadside environment. Most in-cabin pollutants were elevated during the warm season with the notable exception of PNC. PNC was not found to be correlated with most other pollutants. In-cabin concentrations were marginally higher when windows were open.
