Trace elements in human tissue. 2. Estimation of the concentrations of stable strontium and barium in human bone

Abstract
A method is described for the determination of strontium and barium in human bone by radioactivation analysis. Results of analyses of 35 bone samples, from normal persons of both sexes and different ages, are given. The concentrations of Ba and Sr were of the order of 7 and 100 [mu]g/g of ashed tissue respectively. No relationship between sex or disease of individuals with Sr and Ba concentration was noted. The concentration of Sr in the age group l-13years was significantly lower than that in the group 19-74 years. No significant difference was found in the concentrations of Sr and Ba in the various bones of those individuals examined. Results obtained in this survey are discussed and compared with those of other workers.
