Dust particles7/25/2023 This simulation shows how weather conditions can lead to a pollution event affecting air quality. This warm air prevents pollutants from dispersing into the atmosphere, causing a build-up that results in a low-lying horizonal haze.Ī pollution event happens when the concentration of pollutants in the air exceeds acceptable standards. When the Earth’s surface cools quickly, it causes the air at ground level to be colder than the air higher in the atmosphere. These particles are caused by both combustion processes and non-combustion processes.ĭust is a common air pollutant that can impact air quality.īecause dust particles are larger, they pose more of a nuisance rather than the health concern associated with fine particles.ĭry conditions increase the likelihood of airborne dust and dust storms with strong winds carrying soil across long distances.īushfires can also contribute to increased airborne particle levels with smoke travelling hundreds of kilometres and covering large areas.Ĭolder weather can also influence air quality. PM 10 particles are coarse particles measuring less than 10 micrometres in diameter. These particles are mainly caused by combustion processes.įine particles pose a greater health risk because they can reach deeper into the respiratory system and lungs. PM 2.5 are fine particles measuring less than 2.5 micrometres in diameter-that’s 30 times smaller than the width of a human hair. National air quality standards set strict guidelines about acceptable levels of air pollutants.Ī key indicator for air quality is particulate matter, which is measured in two different sizes. Poor air quality can have potentially harmful effects on human health, especially the respiratory and cardiovascular systems. The network includes more than 40 monitoring stations across the state operated by the Queensland Government and industry partners.Īir quality is measured 24 hours a day, 7 days a week and data is published online and updated hourly on the Queensland Government’s live air data website Ĭlean air plays an important role in protecting our health, way of life and natural environment.Īir quality can be affected by a range of pollutants from different sources, as well as weather conditions. Queensland’s air quality monitoring network measures the quality of the air in the environment.
