2015年山东省肉鸡饲料原料中重金属污染情况调查及风险评估
Investigation and Risk Assessment of Heavy Metal Pollution of Feedstuffs in Broiler Chickens in Shandong Province in 2015
摘要
Abstract
The experiment was conducted to investigate arsenic ( As) , lead ( Pb) , cadmium ( Cd) , chromium ( Cr) and mercury ( Hg) pollution of feedstuffs in broiler chickens in Shandong province in 2005, and assess the risk of feedstuffs pollution. Eight feedstuffs including corn, soybean meal, wheat bran, peanut meal, cot-tonseed meal, corn gluten meal, distillers dried grains with soluble ( DDGS) and trace mineral premix used in different feed mills of Laiyang in Yantai, Wendeng in Weihai, Laixi in Qingdao, Zhucheng in Weifan, Juxian in Rizhao, Yishui in Linyi and Xiajin in Dezhou were collected, and the contents of Cd, Pb and Cr were detec-ted by inductively coupled plasma atomic emission spectrometry ( ICP-AES) , and the contents of As and Hg were detected by atomic fluorescence spectrometry ( AFS). Detection rate, average content, over standard rate, the ratio of maximum content to average content ( HC/AC) and coefficient of variance were calculated. The results showed that the detection rates of As, Pb, Cd, Cr and Hg in feedstuffs were 32. 29%, 7. 29%, 12.50%, 100.00% and 100.00%, respectively. Average contents of As, Pb, Cd, Cr and Hg in positive sam-ples were 0.21, 1.27, 2.12, 3.48 and 0.02 mg/kg, respectively. Over standard rates of As, Pb, Cd, Cr and Hg in feedstuffs were 0.00, 1.04%, 1.19%, 54.76% and 9.52%, respectively. HC/AC of As, Pb and Cd in trace mineral premix, Cr in cottonseed meal and Hg in peanut meal were the largest. Coefficient of variance of Cd in trace mineral premix, Hg in peanut meal, As in soybean meal and Pb and Cr in cottonseed meal were the largest. It is concluded that Cr and Hg pollution is most serious in the feedstuffs, and As, Cd, Cr and Pb in trace mineral premix, Cr and Pb in cottonseed meal, Hg in peanut meal and soybean meal are prone to serious pollution in feedstuffs. Therefore, it is necessary to make limited standards of various heavy metal elements in premix and oilseed meals.关键词
