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

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.
