Expert Tips for Minimizing Exposure to ‘Forever Chemicals’ Effectively
PFAS, often referred to as “forever chemicals,” are commonly found in various products due to their water- and stain-resistant properties. With increasing concerns about their potential health risks, including heart disease and cancer, it is essential to understand how to minimize your exposure to these harmful substances.
What do nonstick cookware, waterproof clothing, and anti-fogging sprays all have in common? They typically contain per- and poly-fluorinated alkyl substances—better known as PFAS or “forever chemicals,” a nickname that reflects their indestructible nature.
Manufacturers have been widely using PFAS—a class of about 15,000 chemicals—in products for their stick-, stain-, and water-resistant properties since the 1940s. More recently, scientists have discovered that they can also infiltrate human bodies, entering either through direct contact with items containing them or after leaching out and contaminating food, water, and air.
Scientists are still learning about the health effects of PFAS, “a significant public health challenge” given the large number of them, as noted by Jennifer Freeman, PhD, a professor of toxicology in the School of Health Sciences at Purdue University. Research has so far linked PFAS to a host of health problems, including:
- Heart disease
- Neurotoxicity
- Certain types of cancer
- Preeclampsia
- Thyroid disease
- Liver damage
- Kidney disease
- Delayed mammary gland development
Unfortunately, PFAS are so ubiquitous that there’s no way to avoid them altogether. “Every human on Earth has already been exposed, and some PFAS chemicals will remain in our tissues for decades after exposure,” explained Arthur Daniel Jones, PhD, a professor in the Department of Biochemistry and Molecular Biology at Michigan State University and interim director of the MSU PFAS Analytical Laboratory. However, he and other experts concur that it is possible to minimize your exposure.
Here are eight ways to get started on reducing PFAS in your life:
-
Invest in a High-Quality Water Filter
The good news is that you don’t have to be in the dark about whether your drinking water contains PFAS. The United States Geological Survey has an interactive map to check tap water PFAS levels in your area. If you find concerning levels, filtering your drinking water is an effective way to limit PFAS exposure. Look for filters specifically labeled as PFAS-removing and certified by third-party testers, such as the National Sanitation Foundation.
-
Swap Out Your Cookware
Consider replacing older nonstick pans with PFAS-free options, such as cast iron, glass, or stainless steel cookware. When shopping, look for clear PFAS-free labeling, as some products may only be PFOA-free or PFOS-free, which still might contain other PFAS.
-
Take Stock of Your Seafood Intake
Research has shown concerning levels of PFAS in certain seafood. Filter feeders like clams and bivalves can accumulate these contaminants, and freshwater fish from urban areas may also have higher concentrations. While seafood is nutritious, monitoring your intake, especially of freshwater fish, is advised.
-
Be Mindful When Buying Personal Care Products
PFAS can be absorbed through the skin via personal care items. To limit exposure, check the ingredient lists of products like shampoo, moisturizer, and makeup, avoiding those with fluoro-based ingredients. Apps like Clearya can help you identify PFAS-free products.
-
Avoid Certain Types of Furniture
PFAS are commonly used in furniture and carpeting. Aim to purchase items that are untreated or specifically marketed as PFAS-free. Look for stain-resistant textiles that do not use these chemicals.
-
Shop Package-Free
Many food items are covered in waterproof packaging that can leach PFAS. Seek groceries with minimal packaging, such as those made from glass or foil, or shop at local farmers’ markets. Reducing packaging not only minimizes exposure but also lessens landfill contributions.
-
Limit Fast Food Consumption
Fast food packaging often contains PFAS. A 2022 Consumer Reports study found that nearly all items from top fast-food restaurants tested positive for these chemicals. Limiting fast food can help reduce your exposure significantly.
-
Opt for PFAS-Free Clothing
When purchasing clothing, opt for PFAS-free items. Synthetic materials like nylon and polyester are likely to contain these chemicals. Consider natural materials like cotton, wool, or silk. The Green Science Policy Institute provides comprehensive lists of PFAS-free clothing options.
By implementing these strategies, you can take active steps toward reducing your exposure to harmful PFAS, improving your overall health and well-being.
