AB  - A new analytical method employing gas chromatography coupled to electron capture 
      and nitrogen phosphorus detection (GC-ECD/NPD) has been developed and validated 
      for the screening and quantification of 51 pesticides in a matrix of high 
      chlorophyll content - white mustard (Sinapis alba L.). For preparation of the 
      sample extract, the citrate buffered QuEChERS procedure was followed. However 
      certain changes were made to adapt the method to our needs and available 
      laboratory resources. The sample size was reduced to 5 g, 10 mL water was added 
      and exchange of solvent before GC analysis was done. The samples spiked with the 
      target pesticides at the concentration level 0.01 mg/kg and a higher level 
      (depending on the compound) yielded average recoveries in the range of 70-120% 
      with relative standard deviations (RSDs) 0-19% except for HCB, S-metolachlor and 
      teflubenzuron, and displayed very good linearity (R(2)>0.99) for nearly all the 
      analytes. Limit of quantification was 0.01 mg/kg for the majority of the 
      analytes. The expanded measurement uncertainties were estimated employing a 
      "top-down" empirical model as being between 6% and 32% and yielding an average 
      value of 18% (coverage factor k=2, confidence level 95%).
