What are PFAS?
Per- and polyfluoroalkyl substances (‘PFAS’) are a group of manufactured chemicals that have been widely used globally, since the 1950s, in the manufacture of household and industrial products that resist heat, stains, grease and water.
Examples of PFAS uses include stain protection for carpets, fabric, furniture and apparel; cosmetics; sunscreens; paper coating; plastics; electronic parts for printers and copiers; insecticides; metal plating; photographic materials; aviation hydraulic fluid; and medical devices. Because they are heat resistant and film forming in water, some have also been used as very effective ingredients in fire-fighting foams.
Why are PFAS a problem?
The release of PFAS into the environment has become a concern because these chemicals do not break down easily by any natural process, so they can persist in humans, animals and the environment. Governments across Australia are recommending that people reduce their exposure to PFAS wherever possible, as a precaution, while further research on the potential human health effects continues.
Due to their widespread usage over time, persistence, and mobility in water and soil, PFAS are present in low levels everywhere in the environment. The levels of some PFAS, particularly PFOS and PFOA, are generally declining in the environment naturally over time, as their use in Australia is being reduced wherever possible.
Could I be affected by PFAS?
In the environment
It is important to understand that, due to their widespread usage over time, persistence, and mobility in water and soil, PFAS are present in low levels everywhere in the environment, and most of us will have a detectable level of PFAS in our blood, through exposure to the wide variety of PFAS-containing products in our everyday lives.
There are a number of specific sites across Australia, where run-off from the historical use of PFAS-containing firefighting foams has resulted in increased levels of PFAS in surrounding soil and water. You can find information on these sites on the Australian Government, PFAS Website Investigations page.
Outside of these identified investigation areas, unless you live near industrial areas, landfill sites, or firefighting training grounds where PFAS-containing foams were used, it is unlikely that increased levels of PFAS would be present in your local environment.
