摘　　要：为调查河北省鸡主要饲料原料中重金属污染情况,采集谷物及其加工副产品、膨化大豆、油粕类共计172份样品,采用电感耦合等离子质谱(ICP-MS)法测定其中铬(Cr)、砷(As)、镉(Cd)、铅(Pb)含量。结果表明:稻谷、米糠、玉米蛋白粉、花生粕中Cr超标率均达到100.0%,玉米、小麦、次粉、玉米DDGS、喷浆玉米皮、膨化大豆、豆粕、棉籽粕中Cr超标率分别为9.1%、5.3%、20.0%、50.0%、33.3%、16.7%、40.7%和23.1%;米糠中As超标率为62.5%;花生粕中Cd超标率均为100.0%;玉米、稻谷、小麦、米糠、麦麸、玉米DDGS、喷浆玉米皮、膨化大豆、棉籽粕中Pb超标率分别为1.8%、80.0%、5.3%、12.5%、33.3%、37.5%、33.3%、33.3%、15.4%。绝大多数饲料原料中Cr超标,谷物及其多数加工产品、膨化大豆和棉籽粕中Pb超标,个别饲料As和Cd超标,具有潜在的安全风险。The purpose of this study was to measure the heavy metal contents in main feedstuffs for chicken in Hebei province.The contents of chromium(Cr), arsenic(As), cadmium(Cd) and lead(Pb) in 172 samples including grains,cereal by-products, extruded soybean and oilseed meals in Hebei province were determined by inductively coupled plasma mass spectrometry(ICP-MS). The over standard rates of Cr in rice, rice bran, corn gluten meal and peanut meal were 100.0%. The over standard rates of Cr in corn, wheat, wheat middlings, corn DDGS, corn bran with spray,extruded soybean, soybean meal and cottonseed meal were 9.1%, 5.3%, 20.0%, 50.0%, 33.3%, 16.7%, 40.7% and23.1%, respectively. The over standard rates of As in rice bran was 62.5%. The over standard rates of Cd in peanut meal was 100.0%. The over standard rate of Pb in corn, rice, wheat, rice bran, wheat bran, corn DDGS, corn bran with spray, extruded soybean and cottonseed meal were 1.8%, 80.0%, 5.3%, 12.5%, 33.3%, 37.5%, 33.3%,33.3%, 15.4%, respectively. In conclusion, most feed ingredients were seriously polluted by Cr, most of grains and their by-products, extruded soybean and cottonseed meal were seriously polluted by Pb, and several samples had excessive contents of As and Cd, which was potentially dangerous for animal health and food production.
