Abstract:
ObjectiveTo investigate the characteristics of serum perfluoroalkyl substances （PFASs） exposure and potential influencing factors among community residents in Songjiang District， Shanghai. MethodsIn August 2021， residents who underwent routine health checkups in a community in Songjiang District， Shanghai were recruited as study subjects. The inclusion criteria were adult residents who had lived in the area for more than 3 years， had no occupational exposure history， no underlying diseases， were not pregnant， and were able to complete the questionnaire independently and sign the informed consent form. A questionnaire survey was conducted and venous blood samples were collected. The concentrations of 15 PFASs in serum were determined using ultra-high performance liquid chromatography-tandem quadrupole mass spectrometry （UPLC-MS/MS）. Ordered multi-class logistic regression， interquartile range （IQR）， and odds ratio （OR） were used to explore the influencing factors and risk magnitude of serum PFASs concentrations. ResultsOf the 15 PFASs， 14 were detected， and the detection rates of 7 PFASs were higher than 50%. The highest detected concentrations among the PFASs were PFOS （perfluorooctane sulfonate）， PFOA （perfluorooctanoic acid）， and PFHxS （perfluorohexane sulfonate）， with median concentrations of 48.61 μg∙L-1， 37.29 μg∙L-1， and 36.51 μg∙L-1， respectively. The strongest correlation was between PFDA and PFUnDA （r=0.93， P<0.05）， followed by PFOS and PFDA （r=0.86， P<0.05）. Age， frequency of plastic product use， time spent indoors per day， personal annual income， tea consumption， and daily water intake were potential factors for exposure to PFASs. Among them， age was positively correlated with PFASs； tea consumption was positively correlated with PFNA and PFOA； PFHpA was negatively correlated with the frequency of plastic product use and personal annual income； and PFOS was negatively correlated with the time spent indoors per day. ConclusionThe exposure to serum PFASs among community residents in Songjiang District was relatively serious， and the main components were traditional PFOA， PFOS， and PFHx. Different sociodemographic characteristics had varying degrees of influence on the concentrations of PFASs in serum. The impact of PFASs exposure on the health of community residents deserves further investigation.
