使用移动气溶胶采样系统来确定美国五个城市的大颗粒环境气溶胶粒径分布（粒径高达约 100 μm）：阿拉巴马州伯明翰；北卡罗来纳州三角研究园；宾夕法尼亚州费城；亚利桑那州菲尼克斯；和加利福尼亚州里弗赛德。使用了佛罗里达大学开发的移动式宽范围气溶胶分类器（WRAC）。研究表明，使用尺寸分级入口采样器对环境颗粒物进行的任何测量都会受到环境颗粒尺寸分布的影响。将 WRAC 确定的质量分布测量值与使用 TSP Hi-Vol 和 15 μm 小尺寸可吸入颗粒网络采样器同时获得的质量测量值进行比较。气溶胶尺寸分类结果显示在所有采样点都存在大颗粒质量模式。大粒子模式的位置和大小各不相同，并且不是浓度的简单函数。百分比...
A mobile aerosol-sampling system was used to determine the large particle ambient aerosol size distribution (up to approximately 100 μm particle diameter) in five cities across the United States: Birmingham, Alabama; Research Triangle Park, North Carolina; Philadelphia, Pennsylvania; Phoenix, Arizona; and Riverside, California. A mobile wide range aerosol classifier (WRAC) developed at the University of Florida was used. The study shows that any measurement of ambient particulate matter with a size-fractionating inlet sampler will be influenced by the ambient particle size distribution. Mass distribution measurements determined by the WRAC were compared with mass measurements obtained simultaneously using TSP Hi-Vol and 15 μm cut-size inhalable particulate network samplers. Aerosol size-classification results showed the presence of a large particle mass mode at all sites sampled. The position and magnitude of the large particle mode varied and was not a simple function of concentration. The percentage of ...
