摘      要：[ Objectives] The paper was designed to investigate the heavy metal distribution in energy feedstuffs and protein feedstuffs commonly used in Sichuan Province, in order to provide scientific basis for safe production of feedstuffs and animal products. [ Methods] The contents of manganese （ Mn）, copper （ Cu）, zinc （Zn）, vanadium （V）, chromium （Cr）, cobalt （Co）, nickel （Ni）, selenium （Se）, molybdenum （Mo）, cadmium （Cd）, arsenic （As）, mercury （Hg） and lead （Pb） in 68 samples of energy feedstuffs [ corn, wheat, distillers dried grains with solubles （DDGS）, corn bran with syrup, wheat bran and rice bran ] and 61 samples of protein feedstuffs （corn gluten meal, corn germ meal, soybean meal, rapeseed meal and cottonseed meal） collected from Sichuan province were determined by inductively coupled plasma mass spectrometry （ICP-MS）. [ Results] （ 1 ） The over standard rates of Cu, Cr and Pb in corn were 5.00%, 20.00% and 5.00%, respectively; and thc means of over standard samples were 11.00, 1.41 and 1.06 mg/kg, respectively. The over standard rates of Cu, Zn, Cr, Sc and Pb in wheat were 50.00%, 30.00%, 50.00%, 20.00% and 30.00%, respectively ; and the means of over standard samples were 12.96, 54.67,4.92, 0.53 and 0. 72 mg/kg, respectively. （2） The over standard rates of Cu, Zn, Cr, Se, Cd and Pb in wheat bran were 100.00%, 54.55%, 81.82%, 9.09%, 45.45% and 72.73%, respectively; and the means of over standard samples was 16.01,62.00, 13.96, 0.82, 0.42 and 1.99 mg/kg, respectively. The over standard rates of Cu, Zn, Cr, As, Se, Cd and Pb in rice bran were 83.33% , 16.67% , 83.33% , 83.33%, 16.67% , 66.67% and 100.00% , respectively; and the means of over standard samples were 11.48,64.00, 5.37, 1.05,0.32, 0.23 and 19.57 mg/kg, respectively. （3） The over standard rates of Cu, Zn, Cr, As, Se and Pb in corn germ meal were 25.00%, 37.50%, 75.00%, 12.50% , 25.00% and 50.00%, respectively; and the means of over standard samples were 13.50, 64.00, 6.10, 1.82, 0.46 and 1.66 mg/kg, res
