PFAs: What you should know about these “forever chemicals”

(NC) Let’s talk about per- and polyfluoroalkyl substances, better known by the acronym PFAs. They’re a class of chemicals you might not know by name, but are more common than you think. They’re often referred to as “forever chemicals” because they are extremely persistent.

What are PFAs?

The term refers to a group of thousands of different chemicals that are used as surfactants, lubricants and repellents for dirt, grease and water. They’re found in everything from cosmetics and sunscreens to cookware, electronics, fire-fighting foam and textiles.

There’s a wide range of potential health risks from exposure to PFAS, including impacts on the liver, kidneys and thyroid, the immune, nervous and reproductive systems as well as body weight and metabolism.

Unfortunately, they don’t break down easily and stay in the environment for long periods of time. This means people can be exposed to PFAS in their food, the air they breathe and the water they drink, along with exposures that come from products available to consumers.

What’s being done?

The Government of Canada is proposing to classify most PFAS as toxic substances. This will allow preventive or control actions to be implemented, including potentially restricting their use in products.

You can reduce your exposure by carefully reading product labels on cosmetics and drugs. Avoid products containing PFAS. You might see them listed as “fluoro” or “perfluoro.”

If you’re exposed to PFAS at work, speak to your employer (or occupational health and safety officer if you have one) about safe handling and storage practices, and any relevant laws in place to protect you. You can learn more at canada.ca/healthy-home.
