TI  - Determination of organic micropollutants in rainwater using hollow fiber 
      membrane/liquid-phase microextraction combined with gas chromatography-mass 
      spectrometry.

AB  - A simple and rapid liquid-phase microextraction (LPME) method using a hollow 
      fiber membrane (HFM) in conjunction with gas chromatography-mass spectrometry 
      (GC-MS) is presented for the quantitative determination of 16 polycyclic aromatic 
      hydrocarbons (PAHs) and 12 organochlorine pesticides (OCPs) in rainwater samples. 
      The LPME conditions were optimized for achieving high enrichment of the analytes 
      from aqueous samples, in terms of hollow fiber exposure time, stirring rate, 
      sample pH, and composition. Enrichment factors of more than 100 could be achieved 
      within 35 min of extraction with relative standard deviations (R.S.D.s) 1.3-13.6% 
      for PAHs and 1.7-13.8% for OCPs, respectively, over a wide range of analyte 
      concentrations. Detection limits ranged from 0.002 to 0.047 microg l(-1) for 
      PAHs, and from 0.013 to 0.059 microg l(-1) for OCPs, respectively. The newly 
      developed LPME-GC-MS method has been validated for the analysis of PAHs and OCPs 
      in rainwater samples. Extraction recoveries from spiked synthetic rainwater 
      samples varied from 73 to 115% for PAHs and from 75 to 113% for OCPs, 
      respectively. Real rainwater samples were analyzed using the optimized method. 
      The concentrations of PAHs and OCPs in real rainwater samples were between 
      0.005-0.162, and 0.063 microg l(-1), respectively.
