Main technical content: At present, the methods used to evaluate heavy metals and harmful elements in food, agricultural products, and traditional Chinese medicines mainly include inductively coupled plasma mass spectrometry, atomic absorption spectrometry, and atomic fluorescence spectrometry. However, the determination of heavy metals in hawthorn currently mostly uses atomic absorption spectrometry. However, Jinnan hawthorn contains a variety of minerals, which can interfere with the determination of lead, cadmium, arsenic, mercury, and copper, affecting the test results. Inductively coupled plasma mass spectrometry (ICP-MS) has the advantages of low detection limit (ng/mL or lower), small matrix effect, simple spectral lines, the ability to simultaneously determine multiple elements, a wide dynamic linear range, and the ability to quickly determine isotope ratios. This standard adopts ICP-MS to determine and analyze heavy metals and harmful elements in hawthorn, providing an important reference for the rational development and utilization of hawthorn products and market evaluation.
