Abstract:
Objective To compare the results of three different types of fine particulate matter laser light scattering aerosol monitors and to explore the influencing factors.Methods Three types of Aerosol Monitor A, B, and C were used to monitor the mass concentration of indoor PM2.5 at the same time and place and the membrane weighing method was used at the same time.In order to explore the possible impacts of temperature and humidity indoor on the results of monitoring, a simultaneous monitoring on the temperature and humidity indoor was conducted.The sampling continued 2 days and with 23 hours per day.Results The results of PM2.5 monitored by the three types of aerosol monitors had a good consistency(r were 0.965, 0.988, and 0.984 respectively), but there was significant difference among them(P
