Data of the chemical elements content in blood, placenta, breast milk, hairs of Sariasy region in Surhandarya area inhabitants are given. This region is situated under aluminium work discharge. High content of fluorine and very low levels of selenium, chromium, manganese, iron, cobalt, copper in hairs were noted.
Reviews data on 548 patients with various stages and forms of lymphedema; formed elements of the blood and plasma were analyzed in 84 of these, aged 16 to 64. Zinc, iron, cobalt, antimony, cesium, cerium, selenium, scandium, rubidium, chromium levels were measured by neutral activation technique. Changes in concentrations of plasma trace elements and formed elements of the blood were detected, related to the disease stage. Analysis of blood trace elements in patients with lymphedema appears to be a useful criterion for the assessment of disorders in lymph outflow in various stages of the disease.

The content of 24 elements has been determined in 2000 hair samples of the inhabitants of Uzbekistan. INAA was used for analysis. Reference material IAEA HH-1 and laboratory standards were used. Measurements were done using a Ge(Li) detector and a multi-channel analyzer. No correlation was found between the element content and hair color and ethnic group, whereas the content of some elements depended on sex, hemoglobin content, blood group, and occupation. Arithmetical and geometrical means and medians were calculated. Cumulative histograms show mainly lognormal distributions. Maps of selected regions, based on the elemental hair composition data, were made. The element content was shown to depend on the location of large cities and biogeochemical anomalies. The relationship between the death rate and the element content in hair in some countries has been shown.
