PFAS, or per- and polyfluoroalkyl substances, have emerged as a significant concern in modern environmental health. These man-made chemicals, renowned for their durability and resistance to heat, water, and oil, are ubiquitous in today’s world. Known as “forever chemicals,” they are found in a wide range of consumer products, from non-stick cookware to water-repellent clothing. The public’s awareness of their potential hazards is increasing, but much remains unknown about their long-term effects on human health and the environment.
PFAS are classified as endocrine disruptors, meaning they can interfere with the body's hormone systems. They also fall under the category of microplastics, which are small plastic particles that pose environmental risks. Alarmingly, some companies were aware of the toxic nature of PFAS as early as 1970, long before the broader public health community took notice. Despite this knowledge, these chemicals continued to be used extensively, leading to widespread contamination.
A recent study highlighted the prevalence of PFAS in consumer products, revealing that 72% of water- or stain-resistant brands contain these chemicals. This widespread use raises concerns due to their ability to accumulate in the body over time. Teflon-coated items, commonly used in kitchens worldwide, are particularly concerning for PFAS exposure.
Government agencies like the U.S. Department of Agriculture and the FDA monitor the food supply for PFAS contamination. However, the results of these tests are not always accessible to the public, leaving consumers in the dark about potential risks. Nevertheless, some companies are taking proactive steps to eliminate PFAS from their products. Brands like Patagonia, Jack Wolfskin, and Fjallraven are working to develop waterproof coatings free from these harmful substances.
The movement towards safer alternatives extends beyond outdoor clothing and gear. Blueland, a company focused on simplifying cleaning products without plastic waste, exemplifies efforts to reduce PFAS use. In cookware, companies such as All-Clad and Caraway offer stainless-steel options that avoid these chemicals altogether.
Governmental advocacy plays a crucial role in addressing the PFAS problem. It is essential for governments to limit the presence of PFAS in the environment and to establish clear guidelines on acceptable levels of exposure. Some states, like Maine, are pioneering legislation requiring health insurance companies to cover the costs of PFAS testing. These tests, often referred to as "body burden" tests, typically involve blood samples to measure PFAS levels in individuals. Dr. Gail Carlson explained that these results are often divided into percentiles and compared against CDC data to assess concern levels.
Expert opinions emphasize the importance of informed choices and community action in combating PFAS exposure. Dr. Tracey Woodruff highlights a common misconception: "People buy products with the idea that the government has already regulated or evaluated the chemicals in them for safety – and that's just not the case." This underscores the necessity for consumers to actively seek information from reliable sources.
“Try to get information from original sources – research studies in peer-reviewed journals – or from organizations or departments whose entire missions are public health – like CDC, the World Health Organization, or public health departments in the U.S.” – Manczak
Understanding local environmental conditions is also vital. Dr. Aaron Reuben suggests that learning about one's specific home or community can reveal actionable steps individuals can take to mitigate exposure.
“Learning more about your specific home or community can lead to specific places where you can take action” – Aaron Reuben, PhD
In communities where PFAS contamination is known, interim measures like water filters can provide temporary relief.
“In the interim, the city provides water filters to everyone affected, but I’m shocked by how many families don’t use them” – Manczak
The conversation around PFAS is not limited to individual choices. Dr. Reuben reminds us that broader change requires collective effort:
“You are never going to shop your way to a safer environment; it has to emerge from collective action” – Aaron Reuben, PhD
In addition to government action and informed consumer choices, lifestyle adjustments can help minimize exposure. Carlson advises avoiding certain treatments when installing or cleaning carpets:
“Consumers should avoid treatments like Stainmaster when their carpets are installed or cleaned” – Carlson
For parents concerned about their children's exposure to harmful chemicals, Manczak suggests opting for toys made from wood and fabric:
“For my daughter’s toys, I try to primarily do wood and fabric toys, with extra points to companies that use sustainable production methods – regenerative foresting recycled textiles” – Manczak
These practical steps can contribute to reducing personal exposure while supporting environmentally conscious practices.
