摘　　要：Summary 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.
