AB  - A method combining accelerated solvent extraction (ASE) with magnetic solid-phase 
      extraction (MSPE) and gas chromatography-mass spectrometry (GC-MS) was developed 
      for the simultaneous detection of polycyclic aromatic hydrocarbon (PAH) and 
      organochlorinepesticide (OCP) residues in soil samples. The analytes in the soil 
      samples were extracted using an acetone/n-hexane (1:1, v/v) mixture for 5 min at 
      100℃. Then, the extraction pool was heated for 5 min under an extractive pressure 
      of 11.032 MPa for three cycles. The extraction pool was washed with an 
      acetone/n-hexane (1:1, v/v) mixture accounting for 60% of the pool volume, 
      followed by nitrogen purging for 100 s. The extract was purified by MSPE using 
      self-made magnetic ZIF-8/nZVI materials at room temperature. The analytes were 
      detected by GC-MS/MS. Under the optimized conditions, good linearities were 
      obtained for the 16 PAHs and the 23 OCPs in the range of 5-200 mug/kg, with 
      correlation coefficients (r(2)) above 0.99. The limits of detection (LODs) were 
      0.04-1.21 mug/kg. At three spiked levels in the soil samples, the recoveries of 
      the 39 analytes were between 63.9% and 112.1%, with relative standard deviations 
      (RSDs) between 0.4% and 26.2%. The method was demonstrated to be successful for 
      the determination of 16 PAH and 23 OCP residues in soil samples, with good 
      recoveries.
