The Spatial Distribution of Copper in Individual Human Hairs
Studies of the trace element content of human hair are of interest from several points of view. Since trace elements enter hair from the environment; either directly or via the diet, their concentration in hair may represent an indicator of environmental quality [1–3]. Further, since hair samples are fairly durable, those secured in an historical or archeological context may provide environmental information from times past . Erratum to this paper appears in 21(2).
