AB  - A sensitive and reliable method for determination of polycyclic aromatic 
      hydrocarbons (PAHs) in grilled meat samples was developed and validated. The 
      method is based on magnetic solid phase extraction (MSPE) and GC-MS analysis. 
      Magnetic carbon nanotubes (MCNTs) which have excellent adsorption capabilities, 
      were used as adsorbent to extract PAHs, an important class of carcinogens, from 
      meat samples. To obtain the best extraction yields, the influencing factors, 
      including primary extraction conditions, the amount of adsorbent, adsorption and 
      desorption time, salt addition and desorption solvent were investigated in 
      detail. Under optimized conditions, the LODs and LOQs achieved were in the range 
      of 0.035-0.100 and 0.075-0.200 microg Kg(-1) respectively. The calibration curves 
      were linear (r(2) >/= 0.988) over the concentration ranges from 0.100 microg Kg(-1) to 
      250 microg Kg(-1) The relative standard deviations (RSDs) obtained by carrying out 
      intra- and inter-day precision studies were less than 13.7% and 13.9%, 
      respectively which confirms reproducibility of the method. In addition, the 
      recoveries of analyzed PAHs ranged from 81.3% to 96.7% with the RSDs less than 
      12.7 %. Finally, the established MSPE-GC-MS method was successfully applied to 
      determine PAHs in charcoal grilled/barbecued meat samples. benzo[a]anthracene, 
      benzo[b]fluoranthene, Benzo[a]pyrene and chrysene were detected in beef, lamb and 
      chicken meat samples with the mean cumulative concentration of 4.000, 3.414 and 
      0.931 microg Kg(-1) respectively. Taken together, the MSPE-GC-MS method developed in 
      current study provides a new option for the determination of PAHs in 
      grilled/barbecued meat samples.
