Abstract Herein we describe a method for the simultaneous analysis of 6 heavy metals namely chromium, copper, arsenic, cadmium, mercury and lead in meat and meat products by inductively coupled plasma-mass spectrometry (ICP-MS) after closed-vessel microwave digestion. The analytical method was validated in terms of several parameters. The detection limits of the 6 elements were from 0.15 to 5.52 μg/kg. The linear correlation coefficients were greater than 0.999. The recoveries of standard addition were in the range of 82.0%–110.0%, respectively with relative standard deviations less than 5%. Results indicated that this method has the advantages of easiness, rapidity, high sensitivity and accurate results, and it could be used in laboratories for the routine determination of metal elements in meat and meat products with acceptable analytical performance.
