Suspended particles in the air are also known as dusts, which can cause air pollution if they are high in content, and they contain substances that can affect human health.Dust particles can generally be divided into total suspended particulate matter (TSP), inhalable particulate matter (PM10) and fine dust particulate matter (PM2.5).Here are the differences and relationships between the three kinds of particulate matter.
The major difference between TSP, PM10 and PM2.5 is the size of particle diameter.TSP total suspended particles refer to those with a diameter less than or equal to 100 microns, PM10 refers to those with a kinetic diameter less than or equal to 10 microns, and PM2.5 refers to those with a kinetic diameter less than or equal to 2.5 microns.Among them, PM2.5 and PM10 are particles that can be inhaled into the human body, because these particles contain a large number of impurities, many of which are toxic and will harm the human body.
There is a hierarchical relationship between TSP and PM10 and PM2.5, that is, PM10 is a part of TSP and PM2.5 is a part of PM10. The results show that the weight ratio of PM10/TSP is 60%-80%, while the weight ratio of PM2.5/PM10 is 50%-70%. If the concentration of PM2.5 and PM10 in the air is to be detected, it can be detected by dust sensor.
