Chart air quality data

    Air quality data is available from 1 January 2016. Individual stations have been monitoring for different time periods so data may not be available for all possible times.
    Memorial Park station began monitoring air quality on 1 July 2009.

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 Xylene

Burning organic matter, such as wood, coal and petroleum products generates xylene, and it also occurs naturally in crude oil. Motor vehicle emissions are the predominant source of xylene in the urban air environment.

The standard/guideline for Xylene is 250ppb (24hr avg).
