英文摘要:

      Objective To verify the deviation of inspection methods of total mercury, cadmium and chromium in rice supervision and inspection, so as to improve inspection efficiency and reduce instrument loss. Methods The method was verified from its accuracy, precision and recovery. Results The results of deviation validation were: the accuracy of deviation method was satisfactory; the precision was between 2.60% to 13.88%, within the prescribed range; the recovery rate was between 86% to 106%. Conclusion The deviation method is simple, accurate and efficient, and can be used in rice supervision and inspection.
