What is PM10.0?
PM10.0 is suspended particulate matter, either solid or liquid, with a diameter of 10 micrometers or less. The difference between PM10.0 and PM2.5 is only a matter of size. While PM2.5 is very fine, PM 10.0 is larger and coarser.
Where does it come from?
PM10.0 is any particulate matter in the air with a diameter of 10 micrometers or less, including smoke, dust, soot, salts, acids, and metals.
Particulate matter can also be formed indirectly when gases emitted from motor vehicles and industries undergo chemical reactions in the atmosphere.
Various sources include:
- Dust from construction, landfill, and agriculture
- Dust that blown from open lands
- Wildfire and waste burning
- Industrial sources
- Motor vehicles
How does it affect our health?
Health effects of PM10.0 exposure can vary from difficulty breathing, chest pain, and general respiratory discomfort to lung tissue damage, cancer, and premature death.
Since PM10.0 is a larger particle than PM 2.5, it is less likely to be absorbed by the bloodstream and therefore less dangerous. Its effects are primarily of concern to children, the elderly, and people with chronic lung disease.
PM10.0 reduces visibility and, in some cases, has the ability to corrode organic and inorganic materials. Resulting acid deposition can damage ecosystems.
