abstract = {To detect whether four harmful heavy metals As, Pb, Cd and Hg content in fishery products and meat exceed the permitted levels, this paper provided a method for the on-site and rapid detection of these heavy metal elements. It resulted that the limit of detection (LOD) of four metals in fish were 0.03 mg/kg, 0.02 mg/kg, 0.02 mg/kg and 0.06 mg/kg; the LOD of four metals in bivalves were 0.15 mg/kg, 0.03 mg/kg, 0.30 mg/kg and 0.03 mg/kg; the LOD of four metals in meat were 0.03 mg/kg, 0.06 mg/kg, 0.03 mg/kg and 0.02 mg/kg. Besides, the relative error was As < 10%, Pb < 25%, Cd < 15%, and Hg < 30%. The linear correlation coefficient R2 between the detection value and the reference method (ICP-MS) was ≥ 0.94. The reproducibility accuracy was investigated by comparative test in multiple laboratories, which was As < 10%, Pb < 20%, Cd < 10%, and Hg < 20%. Collectively, this method can meet the requirements of rapid detection of heavy metal elements in fishery products and meat, and the equipment is portable with simple operation, and the detection efficiency has been greatly improved.}
