Per- and poly-fluoroalkyl substances (PFAS) have become infamous recently for their widespread presence in our environment and the health risks they pose. From water contamination to consumer products, PFAS have infiltrated various aspects of our lives.
They have prompted concerns from scientists, policymakers, and the public alike. As awareness grows, so does the urgency to address this issue comprehensively. Countries worldwide are now proposing and implementing bans on PFAS use to mitigate their adverse effects on health and the environment.
In this article, we will explore the reasons behind these worldwide bans on the use of per- and poly-fluoroalkyl substances.
Understanding PFAS: The Silent Threat
Per- and poly-fluoroalkyl substances are a group of synthetic chemicals characterized by their unique carbon-fluorine bonds. These bonds provide remarkable properties such as water and oil resistance, thermal stability, and surfactant properties.
These characteristics make PFAS desirable for various industrial and consumer applications, including non-stick cookware, stain-resistant fabrics, firefighting foams, and food packaging. Therefore, the market for per- and poly-fluoroalkyl substances has been growing exponentially.
However, the properties that make PFAS useful also make them persistent in the environment and resistant to degradation. As a Harvard article states, PFAS chemicals are colloquially known as forever chemicals. This is because these chemicals are persistent and do not break down in the environment for long.
This persistence leads to bioaccumulation in organisms and biomagnification in food chains, posing significant risks to human health and ecosystems.
Health Concerns and Scientific Evidence
The potential health effects of exposure to per- and poly-fluoroalkyl substances have been a subject of intense scientific research and public concern. Several studies have associated PFAS exposure with a myriad of health outcomes.
An article from The Lancet Journal mentions a study that stated the cost of treating forever chemicals-related diseases in the US. The study concluded that the cost could be between $5.5 billion and $62 billion. This shows the extent to which PFAS can impact human health.
These health concerns and per- and poly-fluoroalkyl substances in the environment have spurred calls for quick action. Without immediate action, around 4.4 million tonnes of forever chemicals can be released into the environment by 2053.
The health concerns have also led to increasing lawsuits against per- and poly-fluoroalkyl substance manufacturers. For instance, firefighters are usually exposed to PFAS-based Aqueous Film Forming Foam (AFFF) in their occupation.
According to TorHoerman Law, exposure to forever chemicals in AFFF has made firefighters vulnerable to cancers and other health concerns. Some of the cancers that firefighters are at a higher risk of developing are bladder, breast, rectal, testicular, thyroid, etc.
Therefore, many firefighters have filed lawsuits against the manufacturers. The plaintiffs allege that the manufacturers didn’t warn them about the cancer risks associated with their products. Hence, they seek compensation through firefighter foam cancer lawsuits.
The Global Reach of PFAS Contamination
Forever chemicals contamination knows no boundaries. It has been detected in water bodies, soil, air, wildlife, and even human blood samples worldwide.
One of the most notorious examples is the contamination of drinking water across the US. According to The Guardian, at least 60% of Americans have PFAS in their tap water.
In addition to direct contamination, forever chemicals can migrate from consumer products into the environment during use and disposal. For instance, washing clothes treated with PFAS-based stain repellents can release these chemicals into wastewater.
The sad part is that most Americans are unaware of these risks. Some Texas Water Resources Institute research specialists conducted a study to determine Americans’ knowledge of forever chemicals.
The study found that 45.1% of the participants had never heard the term per- and poly-fluoroalkyl substances. Around 31.6% had heard about PFAS but didn’t know what they were. Moreover, 97.4% did not even believe their tap water had forever chemicals.
Regulatory Responses: A Patchwork of Policies
Recognizing the urgency of the PFAS issue, countries worldwide have started taking regulatory measures to minimize exposure. These measures vary in scope and stringency, leading to a patchwork of policies tackling forever chemical contamination.
There’s also an increased use of proper waste management practices for per- and poly-fluoroalkyl substances. In fact, the PFAS waste management market size is set to grow exponentially. A study from Transparency Market Research shows that it can grow at a CAGR of 5.2% from 2023 to 2031. This will bring the forever chemicals waste management market size to $2.8 billion by 2031.
Here are some ban proposals and regulatory measures taken by the countries worldwide:
United States: Leading the Charge
The Environmental Protection Agency (EPA) has been at the forefront of addressing PFAS contamination in the United States. There is no federal ban on per- and poly-fluoroalkyl substances yet. However, the EPA has set non-enforceable health advisory levels in drinking water for two compounds: perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS).
Additionally, some states have implemented regulations and bans on forever chemicals used in specific products or applications. For instance, Maine has established a timeline to ban PFAS use in all products. Bloomberg Law states that over half a dozen states implement such regulations and bans.
Even the Department of Defense (DOD) is banning per and poly-fluoroalkyl substances-based AFFF firefighting foams. According to Toxic-Free Future, the DOD has recently released a revised specification for purchasing and using forever chemicals-based AFFF. Therefore, investments are being made to find alternatives to these fire suppressants.
Europe: Striving for Comprehensive Regulation
The European Union (EU) has taken a more comprehensive approach to regulating PFAS. In 2020, the EU adopted a Chemicals Strategy for Sustainability, which aims to phase out the most harmful chemicals, including forever chemicals.
Five members of the EU have also recently proposed a ban on the use of PFAS chemicals containing some 10,000 substances. As stated by Medical Device Network, the EU can introduce a complete ban by as early as 2026 if the ban is enacted.
Australia and New Zealand: Addressing Contamination and Exposure
In the Asia-Pacific region, Australia and New Zealand have implemented measures to address PFAS contamination from historical use. Australia has not implemented a country-wide ban. However, an article from The Conversation shows that new regulations can phase out the use of certain forever chemicals chemicals within two years.
New Zealand has also taken measures, specifically in the cosmetic industry. The country has officially released a timeline to ban forever chemicals in cosmetic products by 2026. This means that from 31st December 2026, importing or manufacturing cosmetic products with PFAS chemicals will be prohibited.
Frequently Asked Questions
Which European Countries Are Banning PFAS?
Germany, Denmark, the Netherlands, Sweden, and Norway have proposed a ban on per- and poly-fluoroalkyl substances. These countries have already introduced strict restrictions within their regions, but they are proposing a Europe-wide ban.
