Abstract
Aim: To perform an exposure assessment of arsenic, manganese, mercuryand lead levels in hair samples from children from poor neighborhoods. Materials & methods: A total of38Caucasian children were recruited with the consent of their parents or tutors. Determinations were performed by atomic absorption spectrometry. Results & conclusion: Results were 0.045-0.12μg/g-1 (arsenic), 0.56-2.05μg/g-1 (manganese)and 0.34-27.8μg/g-1 (lead). Lead results did not correlate with those previously reported in blood from the same individuals, suggesting that hair isnotuseful for exposure assessment of this contaminant. Mercury was determined for the first time in Uruguayan children showing levels <0.083μg/g-1. Results revealed low-to-moderate metal exposure, except for some high lead findings.
