Concentration Measuring Method in PM2.5 Monitoring Scheme
Abstract:
PM2.5 is a scientific index used for measuring air pollution degree. WHO proposes PM2.5 less than 10 is safe. However, PM2.5 in many areas of China is higher than 50 and even close to 80, which is much higher than that in Sahara Desert. From the perspective of environmental protection and human's physical health, it is necessary for governmental departments to organize environmental monitoring stations for carrying out PM2.5 concentrations monitoring, using the annual concentration of 35 micrograms/m3 as standard and knowing well the dynamics of PM2.5 concentration with all sorts of flexible monitoring methods. Therefore, concerning about these, a study is made in this paper.
