Chart air quality data
What’s new
Queensland is now reporting hourly averages for PM2.5, PM10 and TSP (instead of a 24 hour running average).
Queensland Health has created 5 health action levels, presented in a colour indicator scale, to provide advice on what activities you can do, based on the hourly average concentrations of PM2.5 in the air.
About Cadmium
Cadmium compounds occur naturally in the environment, particularly in areas of mineralisation. The major emission source is the processing of metal ores for lead, zinc and copper, where cadmium is a valuable by-product.
The guideline for Cadmium is 2µg/m³ (24hr avg).
Cadmium is measured in micrograms per cubic metre.
