Indoor Air Quality Monitoring

Indoor Air Quality (IAQ) has become an important health and safety concern. Indoor exposure to air pollutants may occur in both private and public indoor environments such as office buildings, home, schools and transport systems. And it has been identified as one of the top five most urgent environmental risks to public health by the Environmental Protection Agency’s (EPA).
IAQ problems result from the relations between indoor environment, indoor air contaminants and insufficient air intake or in the other words it comes from interactions of building occupants, material, furnishing, and the climate (temperature, humidity, lighting). Some of the common indoor air contaminants are:
  1. CO2, Ozone, NOx, SOx, perfume, tobacco smoke and other gases – from building occupants, furniture, paints
  2. Dust, dust mite – from fabrics, carpets, furniture, building materials
  3. Toxic vapour, Volatile Organic Compounds (VOCs) – from workplace cleansers, solvent, disinfectants, pesticides, glues
  4. Microbacteria – from damp area
In many circumstances, poor IAQ is related with several health symptoms. Building occupants may report a wide range of health problems or symptoms such as dryness and irritation of the eyes, nose, throat, and skin, headache, fatigue, shortness of breath, allergies, coughing, sneezing and also dizziness. Most people will notice their symptoms after several hours at work and feel better after they have left the building.

By doing Indoor Air Quality Monitoring, we could promote a safe and healthy work environment.
