Work in the Coordinated Programme on Neutron Activation Analysis of Pollutants in Human Hair, Using Research Reactors. Final Report for the Period 1 December 1975 - 30 November 1978

摘要

Scalp hair samples from the population of four different regions in Austria (Vienna, Burgenland, East Tyrol and Vorarlberg) were analyzed by instrumental neutron activation analysis for As, Sb, Cd, Hg, Br and Zn. For each representative group, the range of concentrations, the geometric mean with the antilog of the logarithmic standard deviation and the median were determined. The distribution histogrammes were also given for the frequency as a function of the concentration. The means of concentrations were in the normal range. Thus, no contamination for the population in total could be suspected. A different picture was observed for the Burgenland group. There was a tail of high concentrations of As and Sb superposed upon the usual log-normal distribution. This tail was due to contamination from mines for a part of the Burgenland group. Increased levels of Cd and Zn were also found for this subgroup. This study demonstrated the validity of analysis of scalp hair for the primary monitoring of trace element contamination of man. For this purpose hair has definite advantages over other human specimen available in vivo such as blood or urine. (Atomindex citation 10:483980)
