Abstract A method for simultaneous determination of micro amounts of Cr, Ni, Cu, Zn, As, Se, Cd, Sn, Ba, and Pb in poultry and livestock meat by inductively coupled plasma mass spectrometry, (ICP-MS) was presented. HNO3-HClO4 wet digestion was conducted on samples. The polyatomic elements interference was effectively eliminated using a mixture of hydrogen and helium by collision cell technology (CCT). Sc, Ge, Y, Rh, In, and Re were used as internal standards to correct the matrix interference and drift. The detection limits for the ten elements were in the range of 0.003–0.780 μg/L, and the linear range was between 0 and 200 μg/L for Cu and Zn, and between 0 and 100 μg/L for eight other elements with a correlation coefficient larger than 0.997. The recoveries of these ten elements from spiked meat samples were in the range of 84.80%–131.40% and the RSD was less than 2.60%.
