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 Nitrogen dioxide

Nitrogen dioxide is an acidic and highly corrosive gas. Nitrogen oxides are critical components of photochemical smog. Long-term exposure to high levels of nitrogen dioxide can cause chronic lung disease and affect the senses.

The standard/guideline for Nitrogen dioxide is 0.12ppm (1hr avg).
