PFAS

Sneaky Places At Home Hiding Toxic PFAS Forever Chemicals

By now you’ve heard about PFAS chemicals - the “forever chemicals” most notably associated with non-stick cookware. Its also with plastics pollution and endocrine dysfunction.

But PFAS can be found in many common household items and it is linked to many chronic diseases down the line.

If you have infants or toddlers at home, it's especially important to consider the chemicals that could be in your carpet. For example, rugs are a major source of PFAS exposure for little ones who are likely to put their hands in their mouths after touching the material. 

What are PFAS?


Per- and polyfluoroalkyl substances, or PFAS, is a class of thousands of man-made substances that are common in everyday objects. Peer-reviewed studies have linked them to some cancers, decreased fertility, thyroid disease, and developmental delays, among other health issues.  linked to serious health issues like testicular and kidney cancer, liver damage, thyroid disease, and more, are also hiding out in some pretty surprising places in our everyday lives.

Thanks to their super-strong carbon–fluorine (C–F) bonds, PFAS are extremely stable, making them persistent and resistant to degradation.

PFAS last for decades without breaking down, earning them the "forever chemicals" nickname.

Sneaky places at home that hide PFAS

It may be impossible to completely avoid PFAS, but there are a few simple ways to reduce your exposure. By tackling some of the sneaky places they hide:



Wall paint: One study at Duke University last year found PFAS in six of 10 popular paint brands sampled. The study also determined that in some brands there was off-gassing of PFAS, which reduces the overall concentration of the chemical in the paint on the wall, but disperses it into the air, where it can be inhaled.

Food packaging: PFAS were developed in the 1940s to resist heat, grease, stains, and water. That means they've ended up in a lot of food packaging. That includes pizza boxes, microwave popcorn bags, some wrappers, and grease-resistant paper.

A 2019 study found that people had lower PFAS levels in their blood after eating at home, and higher levels after eating fast food or at restaurants.

Nonstick cookware: The coating used in nonstick cookware usually contains PFAS, and they can easily leach into your food at high heat and once the coating gets scratched.

In fact, overheating nonstick cookware at 570°F or higher leads to the release of harmful chemicals that can cause an illness called "Teflon flu," or polymer fume fever.

In makeup: Cosmetics that are smoothing, long-wear, or waterproof are the ones most likely to contain PFAS chemicals. Without it, your mascara would run. It's a good idea to read ingredient labels (look for any ingredients with ‘fluoro’ in the name).

The Green Science Policy Institute keeps a list of PFAS-free products, including cosmetics brands.

In dental floss: for years, dental floss brands have used PFAS chemicals, which is concerning since it’s a product that goes in our mouths! A 2019 study found that women who flossed with Oral-B Glide had higher levels of a specific PFAS chemical in their blood than women who didn’t use that particular floss. Make sure your floss is PFAS-free!

Soft contact lenses: a random sampling of 18 popular brands of soft lenses sent to an Environmental Protection Agency (EPA)-certified lab all tested positive for PFAS, short for per- and polyfluoroalkyl substances.

Menstrual care products: Mamavation and Environmental Health News conducted a study of PFAS in menstrual care products, including tampons, pads, sanitary napkins and period underwear, and found most of them contaminated to one degree or another with the forever chemicals.

Clothing and textiles: One of the ways fabrics become water resistant is by using PFAS chemicals! Jackets, raincoats, backpacks, and other outdoor gear are often treated with these chemicals.

These fabrics shed fibers that can travel through the house as dust, eventually getting ingested or inhaled.

These same chemicals are used in stain-resistant treatments for upholstered furniture, carpeting, and even curtains. There’s no easy way to know if your items have been treated, especially if they’re older. When it comes time to replace them, seek out brands that don’t use PFAS chemicals.

House dust: Those floaters in the air you see are made up of many things, including chemicals breaking down from various household products, including PFAS. One study found that certain PFAS chemicals were detected in 97-100% of samples! One straightforward solution is to keep your house as clean as possible. Use a water-damp cloth to remove dust (referred to as wet dusting), is a simple way to lower PFAS exposure in your home. lingers in the air and allows humans to breathe the chemicals into their lungs or ingest them. By cleaning regularly, along with opening windows to allow for airflow and ventilation, you can keep dust levels low in your home and reduce the amount of PFAS you swallow.

Tap water: Communities located near military bases, such as Newburgh, New York, often find their water supplies contaminated with PFAS. The pollution can also affect local fish populations and the people who eat them.

PFAS levels in community tap water in Massachusetts reveals a trend of increasing contamination, with total fluorinated compounds exhibiting a 5- to 320-fold rise over 25 years.

People living near military bases are more vulnerable to water contamination. For example, it emerged through internal U.S. documents obtained by journalist Jon Mitchell for The Japan Times that accidental leaks of PFOS-containing fire extinguishing foam at Kadena Air Base may be linked to the contamination of drinking water on the island.

Cellphones / Fingerprint-resistant smartphone screens: PFAS are used in pretty much anything to make things more resistant to grease and water. The circuit boards, semiconductors, and insulated wiring that use PFAS, as well as the touch screen, which has PFAS coating to resist fingerprints.


Must-Watch Documentaries About Toxic Chemicals

Updated 23 July 2024

Embarking on a toxin-free life can be an overwhelming and transformative experience. To help navigate this road, I have found in-depth documentaries to be particularly helpful to understand how these pollutants affect us, including: Documentary films, Multiple Chemical Sensitivity research and lectures, and related eBooks. 

This page is a resource that will help you become an informed consumer.

Living With Multiple Chemical Sensitivities

Toxic chemicals have infiltrated all aspects of modern living — household items, consumer products, electronics, food, food packaging, personal care products, soaps, pharmaceuticals, toys and play mats, and even our water supply.

Imagine having a home that makes you sick. You may make the connections much later to discover how common household items and materials like paint, carpeting, new building materials and insecticides are now your worst enemies. Your bones ache, you’re feverish, you suffer from extreme headaches, disabling fatigue, mental confusion, asthma and nausea.

You realise you are dealing with something called “MCS”, also known as environmental illness, chemical intolerance, and toxicant induced loss of tolerance or TILT.

Are you ill? Or is it your environment that is poisoned?

The longer you stay in your house, the sicker you get but you can’t imagine how or where you’re going to find a safe home. You begin to wonder if you will ever get back to feeling well, and how others respond to your “invisible illness”.

If you have imagined a stronger, more vibrant and happier you, a calm and peaceful home, you are tackling the tasks of living free of toxins. I hope this list is helpful to you and your loved ones to understand the world of MCS.

The Poison in Us All - 2023 (full documentary)

“The Poison in Us All,” a documentary by Bloomberg Investigates, explores the origins of per- and polyfluoroalkyl chemicals (PFAS) or “forever chemicals,” and how they are putting our lives and the lives of future generations at risk.

Rates of cancer diagnosis in children are increasing in Minnesota, USA, which is where chemical company 3M’s global headquarters are located. As far back as the 1960s, the company has been dumping PFAS chemicals in the surrounding areas.

Minnesota sued 3M for the damage that it has caused to the state’s natural resources, and in 2018, the company was ordered to pay $850 million for contaminating the state’s water supply for decades.

The US EPA now recognizes more than 14,000 different chemical structures as PFAS.

Homesick - 2013 (full documentary)

Director Susan Abod hits the road to learn whether other people with MCS are finding safe housing. On her journey to the Southwestern United States, Susan meets people from all walks of life. Their living quarters range from a house on stilts to tents and a teepee.

Funny, You Don't Look Sick: An Autobiography of an Illness

Director Susan Abod also made another film about MCS.

I made a film, the first documentary I made. called "Funny, You Don't Look Sick: An Autobiography of an Illness" was basically about the, you know, having this illness. And--and I took people on a tour through my house and said, 'Well, it looks like a normal place. But you know, there's no carpeting, there's radiant heat, there's no gas stove, there's no paint, nobody smokes in the building. So when I was done with that film, and you know, this was before email, it showed in 1995. And we-- it wound up going to a lot of support groups. And it was by word of mouth or newsletter or something like that. Then it dawned on me that I had this access to--in Boston, there was the American with Disabilities Act, had an arts mini grant available, and I was starting to have trouble with my housing.

I came up with the idea, how to meet others. I mean, simply what you said. And the--a film would be a great way to do it since I didn't have the resources, if I could get money in order to make my van accessible, money to hire a camera woman. So that's what I did. And we only had paper newsletters. And that's how I did it, from phone contact to phone contact to build up a tour of people to talk to. And that's how I did it. — Susan Abod, from podcast interview https://www.chemicalsensitivitypodcast.org/1970633/11732992
