In this preliminary study, scalp hair samples from 36 individuals resident in Sofia, Bulgaria, were analysed and Ag, Al, As, Au, Ba, Br, Ca, Cd, Ce, Cl, Co, Cr, Cs, Cu, F, Fe, Hg, I, K, La, Mg, Mn, Mo, Na, Ni, Rb, S, Sb, Sc, Se, Sn, Sr, Ti, V, W, and Zn were determined. Instrumental neutron activation analysis (INAA) methods were used. Three washing procedures.: distilled-deionised water; acidacetone-water; and Triton X-100 detergent-water, showed a variable elemental change strongly dependent… 
Determination of Hair Element Content in Iranian Population Using INAA
Hair samples were collected from 100 healthy people residing in Esfahan, Iran. The concentration of fourteen elements (Al, Br, Ca, Cl, Cu, Hg, I, K, Mg, Mn, Na, S, V, Zn) were determined by
Determination of trace elements in hair of some local population in Iran by instrumental neutron activation analysis
Scalp hair samples from 100 individual residents in Isfahan, Iran were analyzed for Al, Br, Ca, Cu, Hg, I, K, Mg, Mn, Na, S, V, and Zn by instrumental neutron activation analysis. The results of this

Assessment of reference values for in human hair of urban schoolboys
Summary Hair samples of youngsters (3-15 years of age) from several urban areas of Rome were analyzed to determine the content of 19 minor and trace elements with the aim of assessing Reference
The Effect of Age and Gender on 37 Chemical Element Contents in Scalp Hair of Healthy Humans
It was shown that higher Au, Ca, Mg, and Sr mass fractions as well as lower Cl, Fe, I, Sc, Se, and Sm content were typical of female hair as compared to those in male hair.
The University of Surrey database of elemental composition of human hair
The elemental composition of human hair obtained from different studies at Surrey University over a period of 25 years has been recorded and forms part of a database, for biological and environmental
Determination of Heavy Metals Concentration in Hair Pomades on the Ghanaian Market Using Atomic Absorption Spectrometry Technique
Forty eight (48) hair pomade samples collected from female students at the University of Ghana campus were analysed for heavy metal content using atomic absorption spectrometry technique. The
Elements in scalp hair and nails indicating metal body burden in polluted environment
Heavy metals in biological samples namely hair and nails taken at random were examined in subjects occupationally or otherwise exposed to Pb, Cd, Cu, Mn, Zn, Fe, Ni, Ca, Mg and Cr metals and in


Radioactivation analysis of hair a means of biological monitoring of the environment
With the aim of indicating environmental pollution effects by heavy metals on humans using hair, nondestructive activation analysis was applied to 382 normal Japanese hair samples (background level).
Growth of hair and the trace element profile a study by sectional analysis
Correlations between the growth of hair and the trace element profile have been investigated by non-destructive neuron activation analysis through gamma-ray speetrometry using NaI(Tl) as well as
Trace elements in scalp-hair of persons with multiple sclerosis and of normal individuals.
Scalp-hair samples from 40 multiple sclerosis patients and 42 controls were analyzed by neutron activation analysis, with a SLOWPOKE reactor as the neutron source, and highly significant differences were observed between the two groups in concentrations of Cu, l, Mn, S, Se, and V.
Trace-element analysis in hair: an evaluation.
The use of hair as an index to the concentration of certain elements in tissues has been evaluated with regard to the effect of prior cosmetic and sample-washing treatments on the results. Untreated
Neutron activation analysis of hair failure of a mission
The presence and the concentration of trace elements in hair are subject to variations according to a number of factors. The primary investigations consist in a statistical interpretation of (1) the
Factors affecting the trace-metal content of human hair
Both present-day and historical head-hair samples up to 300 years old are being analysed by neutron activation for more than 30 trace elements. This study, designed to determine an historical
Effect of washing procedures on trace-element content of hair.
The results indicate that the trace-element analysis of hair is sensitive to the preparation technique and therefore is an unreliable source of information about trace- element status.
