Air quality is an important issue in our community. Studies show that air pollution can harm people and the environment.
Air pollution is caused by human activities such as motor vehicle use, prescribed burns and industrial production. Some pollutants also come from natural sources.
The Department of Water and Environmental Regulation leads the focus on air quality for the WA ºÚÁÏÕýÄÜÁ¿ and helps protect air quality in the state by researching, monitoring and working with other groups.
We provide advice to government, other state and local government agencies, industries, and the community about air quality issues like pollution levels, health standards, and how to reduce pollution.
Air quality monitoring
We operate an air quality monitoring network with sites in Perth and regional areas of Western Australia.
Monitoring is carried out according to the requirements of the National Environment Protection (Ambient Air Quality) Measure and improves our understanding of air quality trends, and the potential impacts on Western Australian communities.
