AB  - Sixteen paired surface sediment samples (0-5 cm, n = 32) covering upstream to 
      downstream of water-level-fluctuation zone of Three Gorges Reservoir, China were 
      collected in March 2018 (following six months of submergence) and September 2018 
      (after six months of exposure). Seventeen per- and poly-fluoroalkyl substances 
      (PFASs) were quantified to evaluate contamination characteristics, apportion 
      source categories and estimate mass inventory and loadings. The concentration of 
      SigmaPFASs ranged from 0.26 to 0.82 ng.g(-1) at high water-level (HWL) and 
      0.46-1.53 ng.g(-1) at low water-level (LWL). Perfluorooctanoic acid (PFOA, mean: 
      0.32 ng.g(-1)) and perfluorooctane sulfonate (PFOS, mean: 0.12 ng.g(-1)) 
      dominated, accounting 44.9% and 16.3% of the total PFASs, respectively. The 
      distribution of PFASs was more influenced by anthropogenic activities than 
      physicochemical parameters of the sediments. Positive matrix factorization (PMF) 
      identified PFOA-based products was the major sources (40.1% and 38.6%, 
      respectively). Besides, the direct sources of PFOA-, PFOS-, PFNA-and PFBA-based 
      products played the predominant role, while the indirect degradation of 
      precursors contributed relatively little. The sediment (0-5 cm) mass inventory of 
      PFASs at LWL (57.5 kg) was higher than HWL (39.3 kg). The annual mass loadings of 
      the total PFASs, PFOA, PFOS, perfluoroundecanoic acid (PFUdA) and 
      perfluorononanoic acid (PFNA) from the upstream to the middle-lower reaches of 
      Yangtze River were 27.4 kg, 11.1 kg, 4.63 kg, 2.89 kg and 2.57 kg, respectively. 
      This study could provide the basic datasets of PFASs in surface sediments of the 
      TGR, and also indicate an important transport of PFASs from upstream to the lower 
      reaches, which should be further studied as well.
