About air quality categories
Air quality categories are used to make it easier to interpret air quality data by reducing the complexity associated with different pollutant concentration units and air quality guideline values.
Each air quality measurement from a monitoring station is assigned an air quality category rating based on comparison of the measurement value against the relevant air quality guideline. Five colour-coded air quality categories are used, being ‘Good’ (green), ‘Fair’ (yellow), ‘Poor’ (orange), ‘Very poor’ (red) or ‘Extremely poor’ (dark red). Values greater than the air quality guideline will be appear as ‘Poor’, ‘Very poor’ or ‘Extremely poor’.
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 guideline for Particle PM2.5 is 50µg/m³ (1hr avg) and 25µg/m³ (24hr avg).
Particle PM2.5 is measured in micrograms per cubic metre.
