RESUMEN
The authors give a method of determination of the content of lithium in biological objects (liver, kidney) by the method of flame photometry. It is possible to use this method in forensic medicine in cases of acute intoxication.

A table has been created, presenting normal levels of heavy metals (Hg, Cd, Cr, Cu, Fe, Mn, Pb, Ni, Zn, Sn, Tl, Ag) in human biological media. In contrast to other handbooks, the authors use the normal values derived on the basis of their own investigations at the spectral laboratory of Bureau of Forensic Medical Expert Evaluations, Public Health Committee of Moscow and published reports. Comparative analysis was carried out for each element in human organs, tissues, and urine, which will facilitate expert work. Every laboratory engaged in expert evaluations and analysis in cases with suspected poisoning with heavy metal salts is to have reference values of these elements' concentrations in human organs and tissues obtained in this very laboratory on available equipment with consideration for specific features of its biogeochemical region.

Trials of the Russian x-ray fluorescent crystal diffraction scanning spectrometer Spectroscan A01 manufactured by the Spectron firm in St. Petersburg showed its drawbacks which can lead to erroneous interpretation of the results; this does not permit us to recommend this device for practical forensic medical expert evaluations.

The authors demonstrate the possibility and describe the method for expert evaluation of mercury in biological material (urine, blood, organs and tissues from cadavers) using mercury-hydride attachment to the Carl Zeiss AAS-30 atomic absorption spectrophotometer (Germany). This method is an integral component of chemical toxicological analysis in expert evaluation of poisonings.
