AB  - A simple and rapid focused ultrasound extraction (FU) based method is presented 
      for the determination of persistent organic pollutants (POPs) in soil using a gas 
      chromatography coupled to a mass detector with electron impact ionization. The 
      main experimental parameters affecting the FU step have been optimized by 
      applying a PERMANOVA and PCO analysis allowing us to obtain a maximum amount of 
      information with a minimum number of assays. The limits of detection for POPs 
      fell within the 0.9-6.8 ng/g d.w. interval; a linear method was used with 
      correlation coefficients (r) higher than 0.99. Recovery percentages at low 
      concentrations (25 ng/g d.w.) were 75.8%-110%, and at high concentrations (75 
      ng/g d.w.) 82.3%-109%; the evaluated precision as RSD% of repeatability and 
      reproducibility were within a range of 0.5%-11% and 0.3%-18%, respectively.
