Smoke and dust health action levels

Health action levels are recommendations that have been developed by Queensland Health to support and inform the community on what actions to take to protect their health during a smoke event.

The health action levels are based on hourly PM2.5 measurements and provide separate advice on preventative actions for the general public and for individuals who are potentially more sensitive.

More about the health action levels.

There are elevated health action levels in the following regions:

Measurements as at Sunday 21 July 2024 11pm.

The data used to compile this air quality information comes directly from the department's air monitoring network and has only undergone a preliminary quality check. Data is retrieved from the stations every hour and after quality checks, is available approximately 1 hour later.

All data on this site is shown in Australian Eastern Standard Time (AEST).

An offline message indicates that measurements are temporarily unavailable due to equipment servicing or failure. See network status.

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.
