Indoor and Outdoor Air Quality Monitoring

There is often no one single factor that determines the quality of indoor air in an office space. The indoor air quality of a building is made up of many complex factors that influence human health effects. Concentrations of indoor air pollutants are influenced by changes in activities both within and outside the buildings, cleaning, heating, nearby construction, the degree of ventilation, and the presence of products that are hazardous (including asbestos) or emit that volatile organic compounds (VOCs). Each site is assessed on a site by site basis to determine which contaminants would most likely be affecting the air quality.

Typical contaminates that EnviroX sample for, pending on the site and what is likely to affect the site, include but is not limited to:

  • Carbon dioxide (CO2)
  • Carbon monoxide (CO)
  • Nitric oxide (NO)
  • Nitrogen dioxide (NO2)
  • Asbestos
  • Respirable dust (PM10, 4, 2.5)
  • Mould and fungi
  • Total dust
  • Metals in dust (such as Lead)
  • Volatile organic compounds (VOCs) including formaldehyde
  • Diesel Particulate Matter (DPM)
  • Ozone

EnviroX works with and conducts air quality monitoring following the relevant legislations:

    • Work Health And Safety Regulation 2017.
    • Work Health And Safety Act 2011.

    • AS 3640-2009 Workplace atmospheres – method for sampling and gravimetric determination of inhalable dust.
    • Dust samples are tested as per the Workcover NSW Chemical analysis branch handbook (8th edition).
    • Elemental Carbon (Diesel particulate) Method 5040.
