Trace Elements in Hair, as Related to Exposure in Metropolitan New York

Abstract

Previous studies have revealed that trace element concentrations in hair can reflect exposure in cases of frank poisoning and deficiency. This study reports significant correlations within a single metropolitan area between trace-element content of hair and exposure (as measured by analyses for the corresponding elements in dustfall or housedust) for Ba, Cr, Pb, Hg, Ni, Sn, and V. Age, sex, hair color, and smoking habits were factors included in the statistical evaluation. Several metals increase and decrease together in the hair specimens, in agreement with trends reported for other human tissues.

Investigación de oligoelementos en litos vesiculares de diferentes regiones del estado de Oaxaca por espectroscopia de plasma de acoplamiento inductivo

“…7 En comparación con las concentraciones de elementos tóxicos en pelo en poblaciones de Nueva York, el cobre es tres veces más (x 3), plomo (x 3), níquel (x 14), cromo (x 17), bario (x 15) y estaño (x 135). 8 En relación con los resultados reportados en el sur de la India, el zinc se encuentra más aumentado. 9 Un aspecto preocupante es que los resultados proporcionan indicios de que existen fuentes de exposición prolongadas a compuestos tóxicos en diferentes áreas del estado de Oaxaca, que podrían ser los elementos nucleadores para la precipitación de elementos orgánicos de la bilis y la consecuente formación de la litiasis vesicular.…”

A method to monitor trace elements in the community environment through the chemical analysis of hair.

“…A number of reports have demonstrated that human hair can be used as a reliable monitor of human exposure to toxic elements in the community or working environment. [1][2][3][4][5][6][7][8] In these reports, hair samples were generally collected from inhabitants of different communities or from workers of different industrial firms who had been exposed to a variety of environmental pollutants. In most cases, hair analyses have been performed on an individual basis with the samples collected from a variety of population groups.…”
