AB  - A simple and novel analytical method for quantifying persistent organic 
      pollutants (POPs) in marine sediments has been developed using microwave assisted 
      solvent extraction (MASE) and liquid-phase microextraction (LPME) using hollow 
      fibre membrane (HFM). POPs studied included twelve organochlorine pesticides 
      (OCP) and eight polychlorinated biphenyl (PCB) congeners. MASE was used for the 
      extraction of POPs from 1 g of sediment using 10 ml of ultrapure water at 600 W 
      for 20 min at 80 degrees C. The extract was subsequently subjected to a single 
      step LPME-HFM cleanup and enrichment procedure. Recovery varied between 73 and 
      111% for OCPs; and 86-110% for PCBs, and exceeded levels achieved for 
      conventional multi-step Soxhlet extraction coupled with solid-phase extraction. 
      The method detection limit for each POP analyte ranged from 0.07 to 0.70 ng 
      g(-1), and peak areas were proportional to analyte concentrations in the range of 
      5-500 ng g(-1). Relative standard deviations of less than 20% was obtained, based 
      on triplicate sample analysis. The optimized technique was successfully applied 
      to POP analysis of marine sediments collected from the northeastern and 
      southwestern areas of Singapore's coastal environment.
