      solid matrices in Shanghai, China.

AB  - Perfluorinated acids (PFAs) have been recognized as emerging environmental 
      pollutants because of their widespread occurrences, persistence, and 
      bioaccumulative and toxicological effects. PFAs have been detected in aquatic 
      environment and biota in China, but the occurrences of these chemicals have not 
      been reported in solid matrices in China. In the present study, short- and 
      long-chain PFAs (C2-C14) have been quantitatively determined in solid matrices 
      including sediments, soils and sludge collected in Shanghai, China. The results 
      indicate that sludge contains more PFAs than sediments and soils, and the total 
      PFAs concentrations in sediments, soil and sludge are 62.5-276 ng g(-1), 141-237 
      ng g(-1) and 413-755 ng g(-1), respectively. In most cases, trifluoroacetic acid 
      was the major PFA and accounted for 22-90% of the total PFAs. Although the levels 
      of perfluorooctanoate (PFOA) and perfluorooctanesulfonate (PFOS) were not only 
      lower than trifluoroacetic acid, but also lower than some short-chain PFCAs (<C8) 
      in some individual cases, PFOA and PFOS were still the major pollution compounds 
      in most cases and they constituted 2-34% and 1-9% of the total PFAs, 
      respectively. Meanwhile, unlike previous studies, PFOS levels were not always 
      higher than PFOA in solids collected in Shanghai, China. Given that some 
      short-chain PFAs such as trifluoroacetic acid are mildly phytotoxic and their 
      higher levels in solid matrices were collected in Shanghai, China, these 
      chemicals should be included in future environmental monitoring efforts.
