The biologic bases for using hair and nail for analyses of trace elements.

摘要: Abstract Sampling of human beings for trace element content can be a complex and costly procedure. The use hair nails simplifies the process it is this reason that such samples are extensively used. primary consideration, however, not how easily collected nor even accurately elements measured in nails; rather, what do values mean, i.e., to extent does level reflect concentration and/or activity other parts body? structure histogenesis discussed relation mechanisms by which incorporated into these tissues. Problems contamination vivo also considered. A resume current literature presented, considering appropriate measurement nail some problems involved analysis.
