An overview of PFAS
Per-and poly-fluoroalkyl substances, known as PFAS, are a family of chemicals that are widely used to make water-, grease- and stain-repellent coatings. They are used in a vast array of consumer goods and industrial applications.
Why be concerned about PFAS?
- More than 4,700 PFAS exist, and this number is rapidly growing, as the industry develops new PFAS chemicals that may be even more toxic than existing chemicals
- PFAS are universally detected in soil, water, air, and in the blood, urine, and breast milk of humans globally
- PFAS are used in hundreds of different consumer products and industrial applications, with many human exposure opportunities. PFAS are commonly present in our food and drinking water
- PFAS do not break down in the environment and are called “the forever chemicals”. Certain PFAS chemicals can persist in the body for years
- PFAS are readily absorbed in the gut and quickly enter the bloodstream. Certain PFAS will accumulate in the body with continued exposure, particularly in the liver and kidneys
Reducing exposure to PFAS is the best approach to minimise health risks.

Avoid Teflon™ or non-stick cookwarePFAS are commonly applied to cookware to give it an anti-stick surface. Above 260ºC, coatings begin to break down and release toxic fumes. Safer alternatives include stainless steel, cast iron and ceramic cookware. If you can’t replace your non-stick cookware, there are ways you can minimise your exposure:
Make your own popcornMicrowave popcorn bags usually have PFAS coatings inside that can leach into the popcorn. Toxic fumes are released into the air when the bag is opened. Buy loose corn kernel and pop it on the stove.

Check your drinking waterPFAS are common drinking water contaminants because of their mobility, persistence, and widespread use. Drinking water can be analysed by certified laboratories for commonly occurring PFAS compounds. Reverse osmosis and activated carbon filters can remove some PFAS contaminants. Be sure to select a filter that is certified to remove PFAS to below-drinking water guideline levels.
Choose non-PFAS clothing and sports gearWhere possible, choose clothing that does not carry Gore-Tex or Teflon tags, and be wary of all fabrics labelled stain- or water-repellent. Other products that may be treated include shoes, luggage, and camping and sporting equipment.
Limit fast foods that come in grease-resistant packaging such as hamburgers, pastries and french fries. Studies have detected PFAS in nearly half of tested wrappers.
Some dental flosses contain PFAS and can be a significant exposure route. PFAS can be found in a variety of cosmetics and personal care products, including nail polish, facial moisturisers, eye make-up, shampoo, foundation, sunscreen, and hairspray.
