Measuring air quality
How do we measure air quality?
The National Environment Protection (Ambient Air Quality) Measure (Ambient Air Quality NEPM) includes ambient air quality standards that allow for the adequate protection of human health and well being.
Ambient air quality standards and goals are set for six common pollutants (i.e. carbon monoxide (CO), lead, nitrogen dioxide (NO2), ozone (O3), particles (PM10 and PM2.5) and sulfur dioxide (SO2))
The Office of Environment and Heritage (OEH) operates a comprehensive air quality monitoring network using state-of-art instrumentation to provide the community with accurate and up-to-date information about air quality. Data from the monitoring network is presented online as ambient concentrations and air quality index (AQI) values which are updated hourly and stored in a database. The database provides 1-hour, 4-hour, 8-hour, 24-hour, monthly and annual data. Anyone may access the database using online search tools.
You can either view updated hourly ambient concentrations, AQI values or search and download historical air quality data where you live.
