AB  - Normal methods for benzo[a]pyrene (BaP) determination, including gas 
      chromatography-mass spectrometry and liquid chromatography with fluorescence 
      detection, involve expensive instruments and complex separation and purification 
      processes. Based on membrane enrichment, coupled with solid-phase 
      constant-wavelength synchronous fluorescence spectrometry, a simple, fast, 
      sensitive method was proposed for the determination of BaP in water samples. A 
      Nylon membrane was used as the solid-phase extraction material for enrichment. 
      After enrichment, a constant-wavelength synchronous fluorescence spectrum was 
      scanned directly on the membrane-concentrated BaP without elution. Spectral 
      measurement and enrichment conditions were optimized. Under optimum conditions, 
      when using 150 mL sample solutions, the relationship between fluorescence 
      intensity and BaP concentrations in the 0.05-10.00 mug L(-1) range could be fitted 
      by binomial function with an R(2) value of 0.9973. Limit of detection (LOD) was 
      calculated to be 0.0137 mug L(-1) . The volume of the sample solution was 
      increased to 1000 mL to test if the method could be applied to determine lower 
      BaP concentrations. A linear relationship still existed in the range 2.0-20.0 ng 
      L(-1) BaP with an R(2) value of 0.9895, and a LOD of 2.4 ng L(-1) . The method 
      was also used to measure the BaP concentration in several natural water samples, 
      and recoveries were in the 90-110% range with relative standard deviations (RSDs) 
      in the 0.58-7.93% range. Copyright (c) 2016 John Wiley & Sons, Ltd.
