Investigation of differences in mercury exposure between an industrialized urban population and a non-industrialized suburban population (Pasadena, Calif., and Los Alamos, N. M., respectively) using mercury content of hair as an indicator of exposure. Hair samples were digested in a mixture of nitric acid, sulfuric acid, and potassium permanganate andquantitative mercury recovery revealed concentrations of 18.0 and 18.9 micrograms per gram for Los Alamos men and women, respectively, and 25.0 micrograms per gram for Pasadena women. Results suggest differences in the environmental mercury exposure of the two populations. Since mean values found in this study were higher than those previously reported, the need for a standard reference material for evaluation is suggested.
