The use of L X-ray fluorescence for the determination of the concentration of Pb in human bone has been reported in the literature. A critique of the utility of the method and the shortcomings as an analytical approach in the evaluation of human exposure to Pb are addressed.

Thermal decomposition of Fc4Sn3Br166H2O was investigated by thermogravimetry. The decomposition products were characterized by U.V.-Visible spectroscopy, chemical analysis and X-ray diffraction. The TG curve of the complex showed three decomposition steps. In the first, a mixture of HBr and H2O was evolved. A ferricinium tin bromide compound (Fc4SnBr8) was found to sublime in the second step, whereas a mixture of HBr and H2O was given off in the third, leaving SnO2 as the residue, The stoichiometry of the thermal decomposition of [Fc4Sn3Br16 6H2O] has been established and a possible mechanism for its decomposition is suggested.
