USING TAPERED ELEMENT OSCILLATING MICROBALANCE METHOD TO DETERMINE THE CONVERSION COEFFICIENT OF ATMOSPHERIC PARTICULATE MATTER TESTED BY LASER DUST MONITOR

本研究确定了某激光粉尘仪测试上海市环境大气颗粒物(PM10和PM2.5)的质量浓度转换系数K值。利用激光粉尘仪和TEOM RP 1400a型监测仪,同时对选定的环境监测站同一监测点的环境大气颗粒物(PM10和PM2.5)进行了测定,得出了该激光粉尘仪测试上海市环境大气颗粒物(PM10和PM2.5)的质量浓度转换系数K值呈基本正态分布,分别为0.00594和0.00158。

This paper has determined the mass concentration conversion coefficient of the atmospheric particulates （PM10 and PM2.5） in Shanghai, tested by Laser Dust Monitor. The Laser Dust Monitor and TEOM RP 1400a type’s Atmospheric Particulates Monitor in Shanghai Yangpu District Environmental Monitoring Station are used to test the mass concentration of the atmospheric particulates （PM10 and PM2.5） at the same testing point and time. The mass concentration conversion coefficient of the Shanghai atmospheric particulate （PM10 and PM2.5） tested using Laser Dust Monitor are obtained, the K values basicly appear normal distribution with the values of 0.00594 and 0.00158 respectively.
