Abstract
During the last few years human scalp hair, a horny fibrous derivative of the skin, became well recognized as an invaluable tissue for monitoring human environmental exposure. The sequential accumulation of a number of elements in particular (growth rate of hair strands ca 0.3 mm/day), the fact that the concentrations of trace elements in hair are at least an order of magnitude greater than in the body fluids and other accessible tissues, as well as the simple obtainment and the easy preparation of the specimen, reveal the advantages of this test material. Therefore systematic analyses of concentrations and distribution of arsenic, antimony, cadmium, mercury, bromium and zinc in hair samples obtained from population groups of four Austrian provinces (Bundesländer) were accomplished by INAA. The selection of those regions are based on the distinct economic structure caused by the geographical location as well as the heterogenous geological structure of the country.
Zusammenfassung
Die vorliegende Studie zeigt, daß die Analyse von Spurenelementen (z.T. toxische Metalle) im menschlichen Kopfhaar einen wertvollen Beitrag liefern kann die Umweltbelastung verschiedener Bevölkerungsgruppen abzuschätzen.
Mit Hilfe der instrumentellen Aktivierungsanalyse sind Haaranalysen einfach und gut reproduzierbar durchzuführen, nicht zuletzt deshalb, weil die Elementkonzentrationen in Haaren zumindest eine Größenordnung höher liegen als in den Körperflüssigkeiten, die ja auch als Untersuchungsobjekte dienen.
