TI  - Elaborating the Occurrence and Distribution of Per- and Polyfluoroalkyl 
      Substances in Rivers and Sediment around a Typical Aging Landfill in China.

AB  - Per- and polyfluoroalkyl substances (PFASs) are bioaccumulative and widely 
      distributed persistent organic pollutants (POPs). Understanding the distribution 
      of and ecological risks posed by PFASs is critical, particularly for PFAS 
      emissions and accumulation from a common urban pollution source. The 
      transformation characteristics and ecological risks of PFASs from a typical aging 
      municipal landfill leachate were systematically monitored and assessed over five 
      years in this study. The results showed that the total PFAS concentrations 
      (SigmaPFASs) in the rivers were between 26.4 and 464.3 ng/L, whereas in sediment, 
      SigmaPFASs ranged from 9.5 to 58.5 ng/g (w/w). The presence of perfluorooctanoic acid 
      (PFOA) was the most prominent PFAS in both water (39.4-152.3 ng/L) and sediment 
      (1.1-56.1 ng/g). In a five-year monitoring study, the concentration of PFASs in 
      the aging landfill decreased by 23.3%, with higher mean concentrations observed 
      during summer (307.6 ng/L) compared to winter (250.4 ng/L). As for the pollution 
      distribution, the suspended particulate matter-water partition coefficient (log 
      K(d)) of carboxylic acid (PFCAs) and perfluoroalkane sulfonic acids (PFSAs) 
      ranged from 1.53 to 2.65, and from 1.77 to 2.82, respectively. PFSAs and 
      long-chain PFCAs exhibited a greater propensity for sediment association compared 
      to short-chain PFCAs. An ecological risk assessment of four typical PFASs, PFOA, 
      perfluorooctane sulfonate (PFOS), perfluorobutanoic acid (PFBA), and 
      perfluorobutane sulfonic acid (PFBS), utilizing the hazard quotient method 
      revealed that the rivers surrounding the typical aging landfill exhibited a low 
      contamination risk for PFOA, while no ecological risks were associated with the 
      other three FPASs. This study contributes to an enhanced comprehension of the 
      occurrence, distribution, and risk of PFASs in the rivers in rivers and sediment 
      surrounding a typical aging landfill site in China, thereby providing crucial 
      reference information for ensuring water quality safety.
