Per- and polyfluoroalkyl substances (PFAS) have become commonplace in our everyday lives, from non-stick cookware to waterproof outdoor clothing. These “forever chemicals” are known for their persistence in the environment, as they do not readily break down. With over 15,000 different PFAS chemicals in existence, the widespread use of these substances is evident in the sales of fluoropolymers, which exceeded 39,000 metric tonnes in Europe alone in 2020. As a result, PFAS have infiltrated various aspects of our lives, from rainwater and soil to the food chain and human bodies.
It’s nearly impossible to completely avoid PFAS exposure, given their prevalence in numerous products. However, there are ways to minimize exposure by being mindful of the items we come into contact with on a daily basis. Carpets, sofas, cars, and other fabric-based products treated with PFAS present an opportunity for exposure, making it essential to opt for PFAS-free alternatives whenever possible. Stain-proofing products, traditionally containing PFAS, should be avoided when purchasing items like carpets and sofas. By choosing PFAS-free options, we can significantly reduce our exposure to these harmful chemicals.
PFAS can also be found in items like takeaway boxes, plastic containers, non-stick cookware, and waterproof outdoor clothing. By reducing the use of takeaways and disposable packaging, as well as opting for reusable containers labeled as PFAS-free, we can limit our exposure to these chemicals. When it comes to cookware, replacing non-stick pans with PFAS-free alternatives like ceramic, stainless steel, or cast iron can prevent PFAS from leaching into our food. Similarly, selecting waterproof outdoor gear from brands that offer PFAS-free options ensures that these chemicals do not come into contact with our skin.
Despite the widespread use of PFAS in cosmetics, including skincare and makeup products, their potential toxic effects on human health are a cause for concern. Some studies have shown links between PFAS exposure and various health issues, such as cancer, reproductive problems, hormone disruption, and obesity. Furthermore, PFAS can have detrimental effects on the environment and wildlife, impacting processes like photosynthesis and contributing to increased greenhouse gas emissions. As such, the need for greater caution in the use of PFAS is crucial to mitigate the long-term effects of these chemicals on both humans and the ecosystem.
While some PFAS have been banned under global regulations, there is still much to be done to address the ongoing threats posed by these chemicals. Remediation of PFAS-contaminated waste presents challenges due to their resistance to breakdown, particularly during energy recovery incineration. National regulations on PFAS levels in drinking water vary, with the US implementing limits while the UK lacks statutory guidelines. Moving forward, there is a growing need for stricter regulations and the development of safer alternatives to PFAS to protect public health and the environment alike. Ultimately, the goal should be to phase out PFAS entirely from the market, although this process will require time and concerted efforts from policymakers, manufacturers, and consumers.
