N2 - Trace element contents in specimens of hair collected from 137 children aged 11–13 yearsold, 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 10microg/g (Zn = 189.2microg/g; Cu= 22.9microg/g). Other elements with concentrations greater than 1microg/g were, in order of abundance, Al > Sr > Ba > Pb. The remainingelements were all below 1microg/g. The average elemental concentrations in hair werestatistically 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.
