AB  - Determination of trace chlorophenols (CPs) in environmental samples has been 
      evaluated using liquid-phase microextraction (LPME) coupled with gas 
      chromatography-mass spectrometry (GC-MS) without derivatization. The LPME 
      procedure used to extract CPs from water involved 15 microL 1-octanol as acceptor 
      solution in a 5.0 cm polypropylene hollow fiber with an inner diameter of 600 
      microm and a pore size of 0.2 microm. Under the optimal extraction conditions, 
      enrichment factors from 117 to 220 are obtained. The obtained linear range is 
      1-100 ng mL(-1) with r(2)=0.9967 for 2,4-dichlorophenol (2,4-DCP); 1-100 ng 
      mL(-1) with r(2)=0.9905 for 2,4,6-trichlorophenol (2,4,6-TCP); 5-500 ng mL(-1) 
      with r(2)=0.9983 for 2,3,4,6-tetrachlorophenol (2,3,4,6-TeCP), and 10-1000 ng 
      mL(-1) with r(2)=0.9929 for pentachlorophenol (PCP). The limits of detection 
      range from 0.08 to 2 ng mL(-1), which is comparable with the reported values 
      (12-120 ng mL(-1)). Recoveries of CPs in various matrices exceed 85% with 
      relative standard deviations of less than 10%, except for PCP in landfill 
      leachate. The applicability of this method was examined to determine CPs in 
      environmental samples by analyzing landfill leachate, ground water and soil. The 
      2,4-DCP and 2,4,6-TCP detected in the landfill leachate are 6.68 and 2.47 ng 
      mL(-1). The 2,4,6-TCP detected in ground water is 2.08 ng mL(-1). All the studied 
      CPs are detected in contaminated soil. The proposed method is simple, low-cost, 
      less organic solvent used and can potentially be applied to analyze CPs in 
      complex environmental matrices.
