Navigating the Widespread Reach of 'Forever Chemicals'

Navigating the Widespread Reach of 'Forever Chemicals'

'Forever Chemicals', a term that's emerged in environmental science and public discourse, refers predominantly to a group of synthetic chemicals known as Per- and Polyfluoroalkyl Substances (PFAS). Notoriously persistent in the environment and in living organisms, PFAS have raised substantial concerns among scientists, policymakers, and citizens alike.


PFAS were first synthesized in the 1930s by accident and since the 1940's have been used in a vast plethora of products. PFAS are highly resistant to heat, water, and oil, which made them favorable in an array of applications. Non-stick cookware, stain-resistant fabrics, firefighting foams, and in some industrial processes are just some applications where PFAS's have been found. Despite their utility, PFAS's stability and resistance to breakdown, which has earned the ‘forever’ term, are the very characteristics that render them environmentally and biologically "persistent".

PFAS contamination is global, reaching even the most remote environments.

  • Water Bodies: A study published in the journal "Environmental Science & Technology Letters" found that 6 million Americans consume water with PFAS levels exceeding the U.S. Environmental Protection Agency's (EPA) safety limits. Additionally, a 2019 study found PFAS in rainwater samples across the U.S., affirming their widespread atmospheric presence.

  • Wildlife: Arctic wildlife, despite residing in seemingly pristine environments, is not spared. A study in "Environmental Science & Technology" has shown PFAS accumulating in polar bears, disrupting their hormonal functions and metabolism.

  • Human Impact: Biomonitoring studies, such as those cited by the Centers for Disease Control and Prevention (CDC), have found PFAS in the blood of 97% of the participants, indicating pervasive exposure in the population.

Why is this pervasiveness chemical alarming?

  • Health Risks: Scientific studies, including research from the Agency for Toxic Substances and Disease Registry (ATSDR), have linked PFAS exposure to a plethora of health concerns, including hormonal disturbances, immune system impairment, and increased cancer risks.

  • Environmental Persistence: PFAS does not degrade naturally in the environment, resulting in perpetual contamination of water sources, soil, and ecosystems.

  • Biodiversity Impact: As per the research published in "Science of The Total Environment", PFAS exposure leads to biochemical alterations in aquatic organisms, posing threats to both individual species and biodiversity.

Mitigating the PFAS crisis involves a multi-faceted approach:

  • Regulation: Implementing stringent regulations on PFAS production and use. The EPA has initiated steps to regulate certain PFAS compounds under the Safe Drinking Water Act, though more robust, comprehensive policies are required.

  • Research: Amplifying research on PFAS to unravel its full spectrum of impacts on health and the environment, thereby enabling the development of more effective guidelines and remediation techniques.

  • Public Awareness: Elevating public awareness about PFAS, their sources, and minimizing exposure, is crucial. For instance, choosing products that are PFAS-free and advocating to your politicians for policies that ban the use of PFAS.

  • International Cooperation: Given the ubiquity and transboundary nature of PFAS, international cooperation is indispensable to devise and implement global strategies and guidelines to manage PFAS contamination.

The reality of 'Forever Chemicals' requires a dual responsibility upon us: to mitigate ongoing exposures and impacts and to ensure that future chemical innovations are thoroughly vetted for environmental and health safety. With cohesive efforts among scientists, policymakers, industries, and citizens, strides towards minimizing the PFAS footprint can become a tangible reality.
