Immunity was evaluated in 890 schoolchildren living in rural localities of the Central and Western lands of the Orenburg Region. There was a correlation between the immunological parameters of the examinees and the levels of trace elements in environmental objects. The children's immunity showed unilateral changes in the studied parameters as compared with the regional standards. The closest correlation was found between the absolute count of T lymphocytes, stab neutrophils, the levels of IgA, IgM in children and the content of I, Sr, Mn, Cr in cereals and vegetables, as well as between the levels of IL-2 and alpha-TNF and the blood concentrations of Cu, Fe, Cr, Ni, Co in the examined children. The immunological changes may result from the imbalance of trace elements in the studied environmental objects and biological substrates.

Environmental pollution caused by radioactive and non-radioactive chemicals, and the immunity of schoolchildren who reside in the area exposed to the Totsk nuclear explosion (1954) are comparatively analyzed. The results indicate that the area under study has higher levels of 137Cs than that of a control area. There were immunological changes in children, which are obviously associated with the nuclear explosion.

Radio-ecological and cytogenetic assessments were made in the vicinity of Totsk nuclear explosion in the Orenburg Region. Increased contents of radioactive isotopes Cs and Pu were detected in the soil. A comparative cytogenetic analysis indicated that the population continued to be exposed to radioactive agents.

Environmental pollution of rural settlements in the vicinity of Totsk nuclear explosion was investigated. The findings show that the blanket of snow, soil and drinking water in the polluted area did not differ from those in the control district. High levels of stable strontium in the soil and drinking water and those of iodine in the water were detected. The concentrations of plutonium-239, 240 and cesium-137 in the soil were higher than the levels of global sediments and the baseline values of cesium-137 for the Orenburg Region.
