UK launches its first major study into forever chemicals in humans

The UK government has initiated its inaugural research project aimed at investigating the levels of so-called forever chemicals, or PFAS, within the UK population. Led by the UK Health Security Agency, or UKHSA, the study seeks to gain a clearer understanding of any potential health hazards posed by these persistent substances.

Researchers will collect blood and urine samples gathered through the ongoing Health Survey for England to establish baseline population levels for PFAS, alongside other contaminants such as lead, arsenic, bisphenols, phthalates, and flame retardants.

Per- and polyfluoroalkyl substances have seen widespread industrial use since the 1940s and 1950s due to their resilience against water, oil, and heat. This durability led to their inclusion in thousands of everyday items, including cookware, apparel, and firefighting foams. However, their inability to break down easily in the environment has sparked mounting health concerns.

"We are not all dying because of this but at higher levels and in larger populations they have been associated with adverse health effects."

Professor Tony Fletcher from the London School of Hygiene & Tropical Medicine

Although current evidence suggests that individual health impacts linked to PFAS remain limited, large population studies have established strong connections to elevated cholesterol levels and reduced birth weights. Furthermore, two specific PFAS compounds, PFOA and PFOS, are already banned in the UK due to World Health Organization warnings regarding increased cancer risks from prolonged exposure.
