Distribution of Heavy Metals in Polluted Crops Seeds and the Effect of Heavy Metals in the Food Processing
污染谷物中重金属的分布及加工过程的影响

In this paper,the distribution of cadmium,lead and copper in polluted seeds of rice,wheat and corn,and the removal of heavy metals in processing were discussed.The results showed that the concentrations of Cd,Pb and Cu in different parts of seeds were varies.The concentrations of Cd,Pb and Cu in embryo were higher than that in endosperm.The accumulating contents of Cd,Pb and Cu in endosperm were predominant.The removal ratio of Cd,Pb and Cu in rice was 24 1%,56 9% and 41.0%,respectively,and that in wheat was 61 7%,81 3% and 78 4%,respectively.
