UKHSA is measuring PFAS and other chemicals in blood and urine samples to establish UK exposure levels and inform future health research.
The UK Health Security Agency (UKHSA) is conducting a human biomonitoring study as part of a programme of work to improve understanding of levels of PFAS and other chemicals such as lead, arsenic and flame retardants, in the UK population and the potential implications for health.
PFAS are a large group of human-made chemicals which have been used in a wide range of industrial processes and consumer products. Interest in PFAS has increased in recent years, with communities, researchers and governments seeking to better understand their persistence in the environment and any potential effects on human health.
UKHSA has recently published an evidence review examining the available research on PFAS and health outcomes and is undertaking biomonitoring work to establish baseline levels of PFAS in the UK population. The human biomonitoring study will involve analysing blood and urine samples collected through the existing Health Survey England to understand what substances may be present in the population and at what levels.
Alongside monitoring for PFAS , the samples will also be analysed for levels of lead, arsenic, bisphenols, phthalates and flame retardants. Initial findings from UKHSAโs biomonitoring programme are expected in 2027, which will help build a clearer picture of baseline exposures across the UK population.
