AB  - This study investigated the occurrence of perfluoroalkyl acids (PFAAs) in surface 
      water from 67 sampling sites along rivers of the Pearl River Delta in southern 
      China. Sixteen PFAAs, including perfluoroalkyl carboxylic acids (PFCAs, C5-14, 
      C16 and C18) and perfluoroalkyl sulfonic acids (PFSAs, C4, C6, C8 and C10) were 
      determined by high performance liquid chromatography-negative electrospray 
      ionization-tandem mass spectrometry (HPLC/ESI-MS/MS). Total PFAA concentrations 
      ( summation operator PFAAs) in the surface water ranged from 1.53 to 33.5 ng.L(-1) with an average 
      of 7.58 ng.L(-1). Perfluorobutane sulfonic acid (PFBS), perfluorooctanoic acid 
      (PFOA), and perfluorooctane sulfonic acid (PFOS) were the three most abundant 
      PFAAs and on average accounted for 28%, 16% and 10% of  summation operator PFAAs, respectively. 
      Higher concentrations of  summation operator PFAAs were found in the samples collected from 
      Jiangmen section of Xijiang River, Dongguan section of Dongjiang River and the 
      Pearl River flowing the cities which had very well-developed manufacturing 
      industries. PCA model was employed to quantitatively calculate the contributions 
      of extracted sources. Factor 1 (72.48% of the total variance) had high loading 
      for perfluorohexanoic acid (PFHxA), perfluoropentanoic acid (PFPeA), PFBS and 
      PFOS. For factor 2 (10.93% of the total variance), perfluorononanoic acid (PFNA) 
      and perfluoroundecanoic acid (PFUdA) got high loading. The sorption of PFCAs on 
      suspended particulate matter (SPM) increased by approximately 0.1 log units for 
      each additional CF2 moiety and that on sediment was approximately 0.8 log units 
      lower than the SPM logKd values. In addition, the differences in the partition 
      coefficients were influenced by the structure discrepancy of absorbents and 
      influx of fresh river water. These data are essential for modeling the transport 
      and environmental fate of PFAAs.
