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. Currently, the determination of heavy metals in peach kernels mainly uses atomic absorption spectrometry. However, Jinnan peach kernels contain 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 limits (ng/mL or lower), small matrix effects, 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 the ICP-MS method to determine and analyze heavy metals and harmful elements in peach kernels, providing an important reference for the rational development and utilization of peach kernel products and market evaluation.
