采集内蒙古河套地区小麦样品并分析有毒有害及有益元素含量,对比小麦绿色食品重金属标准可知,前套地区小麦各种有毒有害元素Hg、Cd、As、Pb含量均小于国家小麦标准,为绿色食品;后套地区小麦中的重金属含量基本符合无公害食品卫生标准,不会对人体健康造成危害。前套地区有害元素Cd、Hg在小麦中较为富集,但其含量均低于国家食品标准,对人体健康没有危害性;后套地区小麦中富含人体必需的微量元素Cu、Zn、Se、K,长期食用后套小麦对人体健康是有益的。
The results showed that the content of Hg, Cd, As and Pb in wheat in the front area was lower than that of the national wheat standard, and it was green food. Compared with the standard of wheat, The concentration of heavy metals in the wheat in the back-cover area basically meets the health standards of non-pollution food and will not cause harm to human health. The contents of Cd and Hg, which are harmful elements in the front cover, are more abundant in wheat, but their contents are lower than the national food standards, which are not harmful to human health. The wheat in the back cover area is rich in trace elements Cu, Zn, Se, K, after long-term consumption of wheat is beneficial to human health.
