AB  - A sensitive flame atomic absorption spectrometry (FAAS) method was developed for 
      the determination of cadmium (Cd) in brown rice and spinach. The method involves 
      extraction with 1 M hydrochloric acid (HCl), followed by a selective 
      pre-concentration by solid-phase extraction (SPE). The pH of the loading sample 
      solution was adjusted to 4.0 for the brown rice and to 5.0 for the spinach. The 
      masking agents, tartrate and citrate, were required for the spinach before pH 
      adjustment. The SPE step achieved a 20-fold enrichment of the sample solution. 
      The limits of quantification (LOQs) were 0.0054 mg kg(-)(1) for the brown rice and 
      0.0022 mg kg(-)(1) for the spinach, being more sensitive than those of AOAC Official 
      method 999.10. A single-laboratory validation was performed by testing spiked 
      samples at 0.04 and 0.08 mg kg(-)(1) for the brown rice, and 0.02 and 0.04 mg kg(-)(1) 
      for the spinach. The average recoveries were 93.3-96.9% with relative standard 
      deviations (RSDs) of 4.1-8.2% for brown rice, and 90.5-91.9% with RSDs of 
      5.8-10.0% for spinach.
