In recent years,food security has been paid great attention to in the whole society,with the increasing of living standards of people. However,the pollution of heavy metal which is a hidden way seriously threatens food security. In this paper,analysis of soil heavy metal content in the 14 regions of peanut production in Henan province was developed. The results showed that the variation ranges of arsenic,lead and chromium were 3. 04 - 8. 90mg/kg,5. 53 -18. 30mg/kg and 13.80-43. 60mg/kg, respectively. And their average concentrations were 6. 20mg/kg, 12. 83 mg/kg and 24. 11 mg/kg,respectively,and nocadmium was detected. It indicated that the contents of the 4 kinds of heavy metal were lower than those of the Soil Environmental Quality Standard for the green peanuts.%为明确河南省花生产区的土壤重金属污染情况,对河南省驻马店、开封等14个花生产区的土壤重金属含量进行了测定和分析.结果表明,所测产区砷的含量为3.04～8.90 mg/kg,平均6.20 mg/kg,铅的含量为5.53～18.30 mg/kg,平均12.83 mg/kg,铬的含量为13.80～43.60mg/kg,平均24.11 mg/kg,没有检测到镉.这4种元素在各点的含量以及平均含量均符合无公害和绿色花生基地土壤环境质量标准要求,并达到了一级土壤环境质量标准.
