The X-ray microanalysis method for investigation of chemical composition, mainly trace elements, of normal and pathologic human peripheral blood lymphocytes has been presented. The method in question consists of two stages. During the first stage the scanning electron microscope with the energy dispersive X-ray spectrometer has been used. The second stage of the method consisted of employing the above microscope with the microwave dispersive spectrometer. The method enables the short-term determination of the various elements content within the lymphocytes with particular insight into the content of elements in a single cell. The preliminary investigations showed significant differences in the content of chlorine, sulfur and lead in normal human lymphocytes and that from patients with cancer of the larynx.
