Trace element contents in specimens of hair collected from 137 children aged 11-13 years old, living in Palermo (Sicily, Italy) were determined by ICP-MS. This work reports analytical data for the following 19 elements: Al, As, Ba, Cd, Co, Cr, Cu, Li, Mn, Mo, Ni, Pb, Rb, Sb, Se, Sr, U, V and Zn. The most abundant chemical elements were zinc and copper (Zn > Cu), with concentrations exceeding 10 μg/g (Zn = 189.2 μg/g; Cu = 22.9 μg/g). Other elements with concentrations greater than 1 μg/g were, in order of abundance, Al>Sr>Ba>Pb. The remaining elements were all below 1 μg/g. The average elemental concentrations in hair were statistically compared by Kolmogorov-Smirnov's test taking children's gender into account. Al, Ba, Cr, Li, Rb, Sb, Sr, V and Zn were statistically different according to gender, with significance p < 0.001. This study thus confirms the need for hair analysis to differentiate female data from those of males. IUPAC coverage intervals and coverage uncertainties for trace elements in the analysed hair samples are also reported.
采用 ICP-MS 对来自 137 名 11-13 岁居住在巴勒莫（意大利西西里岛）的儿童的 137 份头发样本中的微量元素含量进行了测定。本工作报告了以下 19 种元素的分析数据：Al、As、Ba、Cd、Co、Cr、Cu、Li、Mn、Mo、Ni、Pb、Rb、Sb、Se、Sr、U、V 和 Zn。最丰富的化学元素是锌和铜（Zn > Cu），浓度超过 10 μg/g（Zn = 189.2 μg/g；Cu = 22.9 μg/g）。其他浓度大于 1 μg/g 的元素按丰度顺序依次为 Al>Sr>Ba>Pb。其余元素均低于 1 μg/g。考虑到儿童的性别，采用柯尔莫哥洛夫-斯米尔诺夫检验对头发中的平均元素浓度进行了统计比较。Al、Ba、Cr、Li、Rb、Sb、Sr、V 和 Zn 的性别差异具有统计学意义（p < 0.001）。因此，本研究证实需要进行头发分析，以区分女性和男性的数据。还报告了分析头发样本中微量元素的 IUPAC 覆盖区间和覆盖不确定度。
