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?

Total Suspended Particulate Matter TSP Monitor

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.

  • Air quality monitoring of underground transportation systems;
  • Laboratories or dust-free workshops for aerosol exposure research;
  • Control and monitoring in the process of drying solids;
  • Dust detectors can also be used for all air particulate emission monitoring applications;
  • Ecological and environmental protection monitoring key to gas construction site dust, PM10, PM2.5, TSP detection, pollutant investigation, etc.;
  • Disease prevention core and health supervision institute monitoring and supervision of inhalable particulate matter concentration in public places;
7 Critical Factors for Choosing an Online Gas Detector

Technical Support

Total suspended particulate matter (TSP) refers to particles suspended in the air with an aerodynamic equivalent diameter of 100μm or less. It is a common air pollutant, along with PM10 and PM2.5, and is commonly used as an air quality assessment indicator.

It can be divided into primary particulate matter (TSP) and secondary particulate matter (TSP). The former is emitted directly from natural or anthropogenic sources (such as dust and industrial smoke), while the latter is generated through atmospheric chemical reactions (such as sulfates converted from sulfur dioxide). Primary sources include fuel combustion, industrial dust, construction dust, and salt particles converted from gaseous pollutants.

First, dust and particulate matter can be harmful to human health. Inhalation can cause respiratory irritation and serious illnesses, such as bronchitis and chronic obstructive pulmonary disease. Some dusts also contain harmful substances, such as heavy metals like lead and mercury in metal dust, which can cause organ damage and toxic effects.

Furthermore, the presence of dust and particulate matter can cause air pollution. For example, dust can reduce air quality, affecting plant growth and soil quality.

Finally, a crucial factor in industry is the potential for explosion. Combustible dust suspended in the air, also known as explosive dust, reaches its lower explosive limit and, upon contact with a fire source, can instantly ignite. The high temperatures cause the gas mixture within the confined space to rapidly expand and increase pressure, resulting in a dust explosion.

Dust explosions typically occur in relatively confined spaces, where the heat and high-pressure gases from the explosion trigger a chain reaction. Any space reached by dust particles can experience a sudden surge of heat and pressure, resulting in extremely serious consequences.
