AB  - Perfluorinated acids (PFAs) are the subject of increasingly intense environmental 
      research. In this study, sewage sludge samples were collected from 25 wastewater 
      treatment plants (WWTPs) in Shanghai, China to evaluate the levels and profile of 
      C3-C14 PFAs. The results showed a ubiquitous PFAs contamination of sewage sludge 
      in Shanghai with the total PFAs ( summation operatorPFAs) range of 126-809 ng g(-1)dw. 
      Perfluorooctanoic acid (PFOA) was found to be the dominant PFA pollutant and its 
      concentration ranged from 23.2 to 298 ng g(-1)dw, much higher than the levels in 
      other countries. Moreover, concentrations of short-chain PFAs (<C6) in sewage 
      sludge were considerable. Following sludge application in agricultural land, the 
      concentrations of PFOA, and perfluorooctane sulfonate (PFOS) are predicted to be 
      1.08 and 7.53 ng g(-1)dw, respectively, much lower than the corresponding US EPA 
      standards. Nevertheless, further studies are needed to explore the fate of PFAs 
      in sludge-amended soils due to the persistence and bioaccumulation potential of 
      these compounds.
