The objective of the present study was to assess the levels of Se, as well as other essential and toxic trace elements in wheat grains and traditional Roti-bread from whole-grain flour in a seleniferous area of Punjab (India) using inductively-coupled plasma mass-spectrometry. Wheat grain and bread selenium levels originating from seleniferous areas exceeded the control values by a factor of more than 488 and 179, respectively. Se-rich wheat was also characterized by significantly increased Cu and Mn levels. Se-rich bread also contained significantly higher levels of Cr, Cu, I, Mn, and V. The level of Li and Sr was reduced in both Se-enriched wheat and bread samples. Roti bread from Se-enriched wheat was also characterized by elevated Al, Cd, and Ni, as well as reduced As and Hg content as compared to the respective control values. Se intake with Se-rich bread was estimated as more than 13,600% of RDA. Daily intake of Mn with both Se-unfortified and Se-fortified bread was 133% and 190% of RDA. Therefore, Se-rich bread from wheat cultivated on a seleniferous area of Punjab (India) may be considered as a potent source of selenium, although Se status should be monitored throughout dietary intervention.
本研究的目的是使用电感耦合等离子体质谱法评估印度旁遮普邦（印度）含硒地区全麦面粉制成的小麦籽粒和传统 Roti-bread 中的硒以及其他必需和有毒微量元素的水平。源自富硒地区的小麦籽粒和面包中的硒含量分别比对照值高出 488 倍和 179 倍。富硒小麦的 Cu 和 Mn 含量也显著增加。富硒面包还含有更高水平的 Cr、Cu、I、Mn 和 V。Li 和 Sr 的水平在富硒小麦和面包样品中均降低。与各自的对照值相比，来自富硒小麦的 Roti 面包还含有更高水平的 Al、Cd 和 Ni，以及更低的 As 和 Hg 含量。含硒面包中的硒摄入量估计为 RDA 的 13600%以上。每天摄入的 Mn 与未强化和强化 Se 的面包分别为 RDA 的 133%和 190%。因此，来自印度旁遮普邦（印度）含硒地区种植的小麦的富硒面包可能被认为是硒的有效来源，尽管在饮食干预过程中应监测硒的状态。
