Frequently Asked Questions

These frequently Asked Questions (FAQs) are the MCIG’s response to a series of questions that have been asked by the Moranbah community.

How do you know if air quality is declining, maintaining or improving?

Maintaining a network of monitoring stations identifies trends over time, such as changes that may be due to demographic, climatic, cultural or land-use changes. Results from monitoring can be used to develop strategies to reduce the impacts of air pollutants and measure how effective implementation of such strategies has been.

Do Air Quality Guidelines exist for Queensland?

Air quality measurements are compared against air quality standards contained in the Commonwealth National Environment Protection (Ambient Air Quality) Measure (Air NEPM) to assess whether pollutant levels could harm public health.

PM2.5 describes particulate matter 2.5 micrometers or less in diameter. PM2.5 is generally described as fine particles. By way of comparison, a human hair is about 100 microns, so roughly 40 fine particles could be placed on its width.


PM10 is a particulate matter that is 10 micrometers or less in diameter.

Total Suspended Particulates (TSP) is a measurement used to determine the total number of suspended particulate matter present in a measured volume of atmosphere. TSP is measured using a High Volume Sampler.
