长江流域饮用水中全氟和多氟烷基化合物的污染特征及人体健康风险评估
Pollution Characteristics and Human Health Risk Assessment of Per-and Polyfluoroalkyl Substances in Drinking Water in the Yangtze River Basin
摘要
Abstract
Per-and polyfluoroalkyl substances(PFASs)have become a global focus of environmental and health research due to their widespread applications,environmental persistence,and potential threats to human health.[Objective]Given the Yangtze River Basin's significance as China's economic lifeline and a densely populated area,the safety of its drinking water is directly linked to public health and ecological security.This study aims to investigate the pollution characteristics,sources,and potential human health risks of PFASs in drinking water along the Yangtze River Basin.A total of 18 water samples were collected from cities along the river,including 3 from upstream,4 from midstream,and 11 from downstream.[Methods]Ultra-high performance liquid chromatography-tandem mass spectrometry was used to measure the types and concentrations of PFASs in drinking water.Hierarchical cluster analysis was applied to identify PFAS sources,and a risk quotient method was used to assess the potential health risks of PFASs to humans in the study area.[Results]The results revealed that eight types of PFASs were detected in the drinking water of the Yangtze River Basin,with total PFASs concentrations ranging from 1.2 ng/L to 67.9 ng/L.The total PFASs mass concentrations in the upstream and midstream drinking water did not exceed 15 ng/L.PFAS pollution was more severe in the downstream areas,primarily attributed to perfluorobutane sulfonate(PFBS)and perfluorooctanoic acid(PFOA).Source analysis indicated that perfluoropentanoic acid(PFPeA),perfluorohexanoic acid(PFHxA),perfluoroheptanoic acid(PFHpA),and PFOA originated from food packaging materials,while perfluorohexanesulfonic acid(PFHxS)and PFBS were linked to nearby textile and paper manufacturing facilities.[Conclusion]Human health risk assessments show that PFASs in drinking water from the Yangtze River Basin pose acceptable risks to all age groups,with no significant short-term health effects.However,the potential risks associated with long-term exposure to PFASs-contaminated drinking water warrant further investigation.关键词
