The UK Health and Safety Authority (UKHSA) is launching the government’s first investigation into levels of “forever chemicals” in the British population. Blood and urine samples will be used to assess exposure to PFAS and other contaminants, including lead and arsenic, with initial results expected next year.
The study aims to improve understanding of the potential health risks associated with per- and polyfluoroalkyl substances (PFAS). Current evidence suggests that the potential health effects are likely to be limited, although the strongest associations identified in larger population groups have been higher cholesterol and lower birth weight.
What are PFAS?
PFAS were widely used in the 1940s and 1950s because they resist water, oil and heat. They are found in thousands of products, including pots and pans, clothing and firefighting foam.
They are often called “forever chemicals” because they do not easily break down in the environment. Health concerns about exposure have increased in recent years.
Two PFAS, PFOA and PFOS, are already banned in the UK. The World Health Organization says that long-term exposure to them can increase the risk of cancer.
PFAS research is still an emerging field, with more than 15,000 studies contributing to the evidence base.
Population testing
UKHSA will use blood and urine samples collected through existing structures, including the Health Survey for England. The samples will be used to establish baseline levels of PFAS, lead, arsenic, bisphenols, phthalates and flame retardants in the population.
Initial results are expected next year.
