We would like to share with you all our monthly report from last months air quality monitoring.
As a kind reminder, please find information below providing an explanation of the components that are measured.
- PM is the term for particulate matter found in the air, including dust, dirt, soot, smoke, and liquid droplets. Some particles are so small that they individually can only be seen with an electron microscope.
- Particulate matter sized 2.5 micro grams per cubic meter are common in indoor environments and are of particular concern for us. This is why we will compare our indoor readings with outdoor readings to ensure our purification systems are working to reduce the presence of these tiny particles. Outdoor readings will be taken from Xinqu outdoor station because this is the nearest outdoor station to our school.
- TVOC refers to total volatile compounds and includes a very wide range of organic compounds that can be emitted from building materials and products.
These organic chemicals have a high vapor pressure at room temperature causing molecules to evaporate and enter the surrounding air as pollutants, for example formaldehyde from paint and adhesives.
