The UK Centre for Ecology & Hydrology is spearheading a new research project to transform our understanding of per- and polyfluoroalkyl compounds (PFAS), also known as “forever chemicals.” Because of their resistance to degradation, these artificial compounds, found in items such as food packaging, firefighting foam, cosmetics, and non-stick cookware, have become a serious environmental hazard. They can linger for decades or even centuries in soil, water, and even living things. This persistence underscores the growing threat of ‘Forever Chemicals’ as they continue to accumulate across ecosystems and potentially pose risks to human and animal health.

Launched in partnership with Lancaster University, the University of Birmingham, the British Geological Survey, and the Ecosystems Agency, the new UKRI-funded project aims to close key information gaps on the movement of these chemicals through the ecosystem and their effects on animals.

Understanding the Problem: What Are ‘Forever Chemicals’?

A class of more than 10,000 synthetic compounds known as PFAS is characterized by its unique resistance to heat, oil, and water. These characteristics make them perfect for domestic and industrial items, but they have a significant negative impact on the environment. Since they are challenging to decompose once released, they can accumulate in soil, water, air, and living things.

• Persistence in Nature: PFAS are known as “forever chemicals” as they can linger in the environment for hundreds of years.
• Bioaccumulation: These substances accumulate in the tissues of animals, including fish and birds, and enter the food chain, potentially affecting human health.
• Health Risks: Research has connected exposure to PFAS to immune system problems, liver damage, hormone imbalances, and some types of cancer.
• Global Presence: PFAS traces have been discovered in everything from deep-sea sediments and Arctic ice to drinking water in cities.

The growing threat of ‘Forever Chemicals’ stems not only from their durability but also from the fact that traditional water treatment and waste management systems are ill-equipped to remove them. This implies that it is practically impossible to eradicate PFAS once they have fully entered the environment.

The UK Project: Filling Knowledge Gaps and Finding Solutions

The goal of the new UKCEH-led initiative is to examine a broader range of PFAS chemicals than previously possible, surpassing the limited set usually examined. From soil and surface water to plants and animals, researchers will monitor the movement of these compounds through multiple environmental pathways and determine how long they persist in each medium.

• Comprehensive Monitoring: To comprehend PFAS movement and accumulation, sophisticated chemical tracing and modeling approaches will be employed.
• Impact Assessment: Researchers will examine how PFAS affect ecosystem health and biodiversity, particularly in freshwater environments.
• Collaborative Approach: By combining environmental research, chemistry, and public policy, the participation of several universities and the Environment Agency guarantees a multidisciplinary viewpoint.
• Informing Regulation: The results will help the UK’s ongoing efforts to strengthen PFAS laws and guide the development of safer chemical substitutes.

This effort is a significant step toward addressing the growing threat of ‘Forever Chemicals,’ a worldwide issue that requires both innovation and international collaboration to fill substantial research gaps.
