AB  - A simple and sensitive method combining solid-phase extraction (SPE) and 
      high-performance liquid chromatography-ultraviolet detection (HPLC-UV) was 
      developed for the determination of benzo[a]pyrene (BaP) in fish. Loofah sponge 
      (LS) was carbonized and used as an SPE adsorbent. Carbonization decreased the 
      polarity of LS and enhanced its aromaticity. Carbonized loofah sponge (CLS) could 
      capture BaP better through pi-pi interaction. The carbonization temperature and the 
      SPE conditions were optimized. The linear range of the developed method was 
      within 10-1000 ng g(-1) with a satisfactory correlation coefficient (R(2)) of 
      0.9999. The limit of detection (LOD) was 2.0 ng g(-1), which was below the 
      maximum residue limit (5 mug kg(-1)) in meat set by the European Union. The method 
      showed good intra-day and inter-day precision with relative standard deviations 
      (RSDs) ranging from 0.4% to 1.7%. Finally, the developed method was applied to 
      the determination of BaP in fish samples. This method is low-cost and 
      environmentally friendly with natural and renewable LS as raw material and it 
      provides an alternative approach for the efficient and simple determination of 
      BaP in aquatic products.
