The aim is to establish baseline exposure levels. Lead, arsenic, bisphenols, phthalates and flame retardants are also included, according to the agency.

UKHSA expects initial programme findings in 2027. Detecting a substance does not by itself establish an individual health risk: the agency points to gaps in understanding long-term effects and does not recommend routine PFAS blood screening.
