This study was performed to investigate trace elements and arsenic contents among Sudanese inhabitants living in the north, east, and west of Sudan. Inductively coupled plasma atomic emission spectrometry was used to determine the contents of Zn and Cu. Graphite furnace atomic absorption spectrometry was used to determine Se in serum samples. It was found that Se and Cu are in the normal range. Zinc showed discrepancies among all studied groups. Acute Zn deficiency was detected in the northern and eastern regions of Sudan. Inductively coupled plasma mass spectroscopy was operated in the dynamic reaction cell mode to determine the arsenic content in the nail samples of the northern inhabitants of Sudan. High values of arsenic were found in the northern people compared with the control group. This elevation could be linked to the misuse of insecticides and herbicides which might be associated with the high rate of cancer incidence in this region.
本研究旨在调查生活在苏丹北部、东部和西部的居民体内的微量元素和砷含量。采用电感耦合等离子体原子发射光谱法测定 Zn 和 Cu 的含量。采用石墨炉原子吸收光谱法测定血清样本中的 Se 含量。结果发现，Se 和 Cu 均处于正常范围，Zn 在所有研究组中存在差异。苏丹北部和东部地区存在急性 Zn 缺乏症。采用电感耦合等离子体质谱法在动态反应池模式下测定苏丹北部居民的指甲样本中的砷含量。与对照组相比，苏丹北部人群的砷含量较高。这种升高可能与杀虫剂和除草剂的滥用有关，而杀虫剂和除草剂的滥用可能与该地区癌症发病率高有关。
