Exposure to Emerging and Legacy Polyfluoroalkyl Substances in the Sixth Total Diet Study — China, 2016–2019

WHAT IS ALREADY KNOWN ABOUT THIS TOPIC? Perfluoroalkyl substances (PFASs) are persistent organic pollutants, which have multi-organ toxicity and potential health risk to humans. WHAT IS ADDED BY THIS REPORT? The most commonly detected PFASs in the Sixth China Total Diet Study (TDS) samples were perf...

Sumario:WHAT IS ALREADY KNOWN ABOUT THIS TOPIC? Perfluoroalkyl substances (PFASs) are persistent organic pollutants, which have multi-organ toxicity and potential health risk to humans. WHAT IS ADDED BY THIS REPORT? The most commonly detected PFASs in the Sixth China Total Diet Study (TDS) samples were perfluorooctanesulfonate (PFOS), perfluorooctanoic acid (PFOA), perfluoroundecanoic acid (PFUdA), perfluorodecanoic acid (PFDA), perfluorononanoic acid (PFNA), and 9-chlorohexadecafluoro-3-oxanonane-1-sulfonate (6:2 Cl-PFESA). The mean estimated weekly intakes (EWIs) of PFOA, PFOS, and 6:2 Cl-PFESA in the Sixth TDS were 2.17, 2.72, and 2.75 ng/kg body weight per week, respectively. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE? The PFASs levels in some food category and dietary exposure still need to be continuously monitored, especially for 6:2 Cl-PFESA.
