Research works that would determine the content of chemical elements in black population organisms on the basis of hair analysis are not numerous. There are no studies referring to black populations living in indigenous environment, like the Mafinga region, Iringa District in Tanzania examined by us. The aim of the study performed was to analyse the content of chemical elements Fe, Ca, Mg, Zn and Cu in easily available biological media like hair. The material was collected in October 2005 and March 2006 during anthropological examination, which came from young males (n = 91), students of a secondary school. Large Ca concentration range was found for the total number of subjects (680.20 to 2,089.70 µg/g d.m.). Mean Fe content in hair for the total number of subjects was 11.19 ± 3.70 µg/g d.m., while that of Mg 6.84 ± 2.02 µg/g d.m. Mean Zn concentration for the total number of subjects was 91.06 ± 39.22 µg/g d.m., being significantly higher in younger group than in older one (p = 0.039). Mean Cu concentration in hair for the total number of subjects was 7.50 ± 2.90 µg/g d.m Body mass index (BMI = kg/m²) was calculated for the subjects showing that out of 91 men participating in the study 15.4% was characterised by mediocre nutrition. No statistically significant correlations were found between BMI and the analysed chemical elements. The analysis of the content of trace elements in the hair of the examined young males showed deficiencies in Zn, Cu, Fe and significantly in Mg.
基于头发分析来确定黑人群体中化学元素含量的研究工作并不多。我们研究的坦桑尼亚伊林加区马芬加地区的黑人生活在原始环境中,目前还没有针对这一人群的研究。本研究旨在分析易于获取的生物介质(如头发)中的化学元素 Fe、Ca、Mg、Zn 和 Cu 的含量。该材料于 2005 年 10 月和 2006 年 3 月在人类学检查期间收集,来自一所中学的年轻男性(n=91)。我们发现所有研究对象的 Ca 浓度范围都很大(680.20 至 2089.70μg/g 干重)。所有研究对象的头发中平均 Fe 含量为 11.19±3.70μg/g 干重,Mg 为 6.84±2.02μg/g 干重。所有研究对象的头发中 Zn 平均浓度为 91.06±39.22μg/g 干重,年轻组明显高于老年组(p=0.039)。所有研究对象的头发中平均 Cu 浓度为 7.50±2.90μg/g 干重。为参与研究的 91 名男性计算了体重指数(BMI=kg/m²),结果显示 15.4%的人营养状况中等。我们没有发现 BMI 与分析的化学元素之间存在统计学上的显著相关性。对所研究的年轻男性头发中微量元素含量的分析表明,Zn、Cu、Fe 以及 Mg 明显缺乏。
