Abstract

Various combinations of hi-vol samplers, size-selective inlet and two cascade impactors were tested near a highway. The Sierra 235 cascade slot impactor yielded low total dust values and very small apparent aerodynamic diameters. Sampling with the size selective inlet was found to correlate satisfactorily with hi-vol data. The effect of humidity on the mass of field collected dust is also discussed.

摘要

在一条高速公路附近对大容量采样器、尺寸选择性入口和两个串级冲击器的各种组合进行了测试。Sierra 235串级狭缝冲击器的总粉尘值较低，表观空气动力学直径非常小。发现使用尺寸选择性入口进行采样与大容量数据具有令人满意的相关性。还讨论了湿度对现场采集粉尘质量的影响。
