You’ve likely heard of PFAS, aka “forever chemicals.” These man-made substances accumulate and persist in the environment and the human body over time. Studies link PFAS to health issues like cancer and problems with the immune system.
While you might be aware of some common sources of PFAS exposure, several surprising items could increase your exposure risk. Let’s explore five unexpected sources of PFAS that might be part of your daily life.
#1. EV Batteries
Electric vehicles (EVs) are celebrated for being environmentally friendly, but did you know they could be a source of PFAS pollution?
The lithium-ion batteries used in many EVs contain bis-perfluoroalkyl sulfonimides (bis-FASIs) due to their chemical stability and resistance to heat. These properties make bis-FASIs ideal for battery manufacturing. However, it also means that PFAS can be released into the environment during production and disposal. The Verge states that as the demand for EVs increases, so does the potential for PFAS pollution.
If these batteries are not disposed of properly, PFAS can leach into the soil and water, contributing to long-term environmental contamination. This issue is particularly concerning because the growing use of lithium-ion batteries could increase PFAS exposure through everyday products.
#2. Freshwater Fishes
Fish is considered a healthy food choice. But, if you enjoy fishing in freshwater lakes or rivers, you might be consuming something more than just omega-3s. PFAS has been found in freshwater fish across the United States, and the problem is that it accumulates in fish over time.
An Environmental Working Group study found that eating one serving of these fish could be equivalent to drinking PFAS-contaminated water for a month. The Environmental Protection Agency (EPA) further reveals that freshwater fish had over 270 times the PFAS content compared to industrially harvested fish.
This is particularly concerning for communities that rely heavily on freshwater fish as a food source. This doesn’t mean you should avoid fish altogether. Instead, diversify your protein sources and be aware of local fish advisories.
Aqueous film-forming foam (AFFF) containing PFAS has been a significant contributor to water contamination. The foam was once commonplace in firefighting during the 1970s. However, TruLaw reveals that it caused groundwater and soil contamination near military stations, airports, firefighting training institutions, and AFFF manufacturing plants.
This resulted in the AFFF foam lawsuit, as the residents living near these areas experienced horrifying symptoms, including various cancers and thyroid issues. Experts state that as of August 2024, over 9,520 cases are in the pipeline.
#3. Reproductive health products
You might not expect harmful chemicals in products designed for personal safety and comfort, but PFAS are often used in lubricants and condoms. These substances create a smooth, non-stick surface and help increase product durability.
However, this convenience comes at a cost. A recent study by Mamavation found PFAS in various lubricants and condoms available on the market. Out of the 29 products tested, about 15% contained detectable levels of fluorine, indicating the presence of PFAS. 3 out of 25 condoms and 1 out of 4 lubes had noticeable fluorine levels exceeding 10 parts per million.
PFAS in lubricants and condoms can be absorbed through the skin, posing potential health risks. Over time, exposure to these chemicals can build up in the body, leading to adverse effects. Given the intimate nature of these products, it is crucial to be aware of the potential for PFAS exposure and to seek PFAS-free alternatives whenever possible.
#4. Soft and Aerated Drinks
Your favorite soft drinks and sparkling waters might be another unexpected source of PFAS exposure. These chemicals can leach into beverages from packaging materials, contaminated water sources, or during packaging.
Recent lawsuits have brought attention to this issue. For instance, a class action lawsuit was filed against Prime, a popular energy drink, alleging that it contains PFAS. Similarly, concerns have been raised about PFAS in sparkling water brands. Yahoo reports that nine brands had PFAS concentrations over 1 part per trillion (ppt).
While PFAS in some drinks is often low, regular consumption could increase exposure. Consider opting for beverages in glass bottles or brands committed to PFAS-free packaging.
#5. Paints
You might not think twice about the paint you use in your home, but paints often contain PFAS. They help improve water resistance, shelf life, durability, and flow. While it enhances the paint’s capabilities, it also means that your home could be a source of ongoing PFAS exposure.
A Healthy Building Network report found that PFAS are present in about 50% of paints, including those used for buildings, automobiles, and art supplies. The research found fluorine, a PFAS indicator, in all paint brands. Its concentration levels varied from 30 to over 90%. These chemicals can be released into the environment during the application, weathering, or disposal of painted items.
To reduce your exposure, look for paints certified as PFAS-free. Some organizations, like Green Seal, have announced they won’t certify any paints, floor cleaning products, or coatings containing PFAS. The agency revealed it would test for about 12,000 PFAS chemicals. Green Seal certification is the gold standard for integrity and environmental welfare in the marketplace.

PFAS can remain in your body for years. The half-life (time for half the chemical to leave your body) varies by compound, ranging from 3 to 7 years for common PFAS like PFOA and PFOS. However, ongoing exposure can lead to accumulation over time.
Use natural fiber clothing, cast iron, or stainless-steel cookware; filter your drinking water, and avoid fast food packaging. Check product labels for PFAS-free claims, and choose personal care products without “fluoro” ingredients. Every small measure helps minimize your exposure.
Yes, many such alternatives exist. Look for clothing treated with natural water repellents, use beeswax wraps instead of non-stick food packaging, and select mineral-based or silicone-free cosmetics. For outdoor gear, seek brands using PFC-free water-repellent treatments. Always research and read labels carefully.
PFAS is a serious problem that can come from unexpected sources in your daily life. From EV batteries to paints, these “forever chemicals” are more commonly found than you might think. While it’s nearly impossible to avoid PFAS, knowing these unusual sources can help you make better decisions.
Stay updated on the latest PFAS developments, and look for PFAS-free alternatives when possible. In addition, support initiatives that aim to reduce the use of these persistent chemicals in consumer products.
