| a: Refers to dust with free SiO2 less than 10%, no asbestos and toxic substances, and no allowable concentration has been established. All kinds of dust listed in the table (except asbestos fiber dust) with free SiO2 higher than 10% are treated as silica dust allowable concentration. For dust, the excessive fluctuation of its short-term exposure level is controlled by the over-limit multiple. Under the premise of meeting PC-TWA, the over-limit multiple of dust is 2 times of PC-TWA. | ||||
What is the Difference between TSP, PM10, and PM2.5?
Suspended particles in the air are dust. If the content of these suspended particles in the air is high, it will cause air pollution. The various substances contained in these dust particles can affect human health. Dust particles can usually be divided into: total suspended particles (TSP), inhalable particles (PM10), and fine dust particles (PM2.5). Here I will introduce the differences and relationships between these three types of particles.
The main difference between the three types of particles, total suspended particles (TSP), inhalable particles (PM10), and fine dust particles (PM2.5), is the size of the particle diameter.
- TSP, also known as PM100, total suspended particles, refers to particles suspended in the air with an aerodynamic equivalent diameter of ≤100μm.
- PM10 refers to particles with a dynamic diameter of ≤10μm.
- PM2.5 refers to particles with a dynamic diameter of ≤2.5μm.
Among them, PM2.5 and PM10 particles are particles that can be inhaled by the human body. Because these particles contain a large amount of impurities, many of which are toxic substances and can cause harm to the human body.
TSP and PM10 and PM2.5 have a layered relationship of inclusion, that is, PM10 is part of TSP, and PM2.5 is 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 you want to detect the concentration of PM2.5 and PM10 in the air, you can use a dust concentration detector to detect it.
Featured Applications of Dust Detectors
