The Vertical Change of Atmospheric Particulates and Evaluation on Its Influence of the Resident's Floor-Choosing in Beijing

摘要

In order to investigate the vertical change of atmospheric particulates and it’s influence of the resident’s floor-choosing in Beijing,we take PM10 as the research object,the 18th building whichis 49.2 m in height of China University of Geosciences as the representative of resident building in Beijing,use the TSP/PM 10/PM2.5-2 particulate-sampling machine to sample PM10 on the south balcony of 1,4,8,12,16th floor respectively in 72 hours from 12 o’clock of January 31st to 12 o’clock of February 2nd,2007, weigh the accurate weight of the fiberglas filter membrane on the Sarlorius electronic balance
