About air quality index values
Our scientists create an air quality index by converting measured pollutant concentrations into index values which make it easier to interpret air quality data by reducing the complexity associated with pollutant concentrations.
The index value is the pollutant concentration expressed as a proportion of the National Environment Protection Measure for Ambient Air Quality (Air NEPM) standard or the Environmental Protection (Air) Policy 2008 (Air EPP) objective.
About Particle PM2.5
Airborne particles less than 2.5 micrometres in diameter, referred to as PM2.5, can be hazardous to human health or cause a nuisance when present in the air at elevated levels. They are capable of penetrating the lower airways of humans and can cause possible negative health effects.
The standard/guideline for Particle PM2.5 is 25µg/m³ (24hr avg).
