Build a Mobile Vehicle for In-Situ Measurement of Dust of UFP and PM1 |
摘要: |
This project will develop a mobile vehicle equipped with particle size analyzers for in-situ measurement of traffic-generated Ultrafine Particles (UFP, particles with a diameter of 0.1 micrometers or less)) and PM1 (particles with a diameter of 1.0 micrometers or less). The vehicle is different from existing systems which currently measure PM10 (particles with a diameter of 10 micrometers or less) or PM2.5 (particles with a diameter of 2.5 micrometers or less). The existing systems can not determine UFP and PM1 which are considered to be a significant human health concern because of the variable composition and the ability of these particles to penetrate deeply into the respiratory tract. The vehicle being developed can measure both particle number concentration and particle size distribution, while the existing systems can only measure the particle number concentration. When the vehicle travels on a predetermined route in urban areas such as Las Vegas, the obtained particle size distribution data would help to develop fine particle emission inventories. This would be the first system of its kind with these capabilities, and may help develop understanding of the emissions of ultrafine particles. |
