Abstract

Aim: To perform an exposure assessment of arsenic, manganese, mercury and lead levels in hair samples from children from poor neighborhoods. Materials & methods: A total of 38 Caucasian children were recruited with the consent of their parents or tutors. Determinations were performed by atomic absorption spectrometry. Results & conclusion: Results were 0.045-0.12 μg/g^-1 (arsenic), 0.56-2.05 μg/g^-1 (manganese) and 0.34-27.8 μg/g^-1 (lead). Lead results did not correlate with those previously reported in blood from the same individuals, suggesting that hair is not useful for exposure assessment of this contaminant. Mercury was determined for the first time in Uruguayan children showing levels <0.083 μg/g^-1. Results revealed low-to-moderate metal exposure, except for some high lead findings.

乌拉圭儿童头发中砷、铅、锰和汞的生物监测。

目的:对贫困社区儿童头发样本中的砷、锰、汞和铅水平进行暴露评估。材料与方法:经父母或导师同意，共招募38名白人儿童。采用原子吸收光谱法测定。结果与结论:砷含量为0.045 ~ 0.12 μg/g-1，锰含量为0.56 ~ 2.05 μg/g-1，铅含量为0.34 ~ 27.8 μg/g-1。铅的检测结果与先前报道的同一个人的血液中铅的检测结果没有相关性，这表明头发对这种污染物的暴露评估没有用处。首次在乌拉圭儿童中检测出汞水平为-1。结果显示低至中度的金属暴露，除了一些高铅的发现。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
