[Element composition of aerosol exhaust from thermal stations using coal].
Out of the whole number of impurities (more than 30) detected in aerosol discharge of TES using Cheliabinsk mine coal only for 16 of them MACs for the air of residentials areas or tentative safe exposure levels were established. The most important from the hygienic point of view are dust, aluminum, iron, manganese, barium, vanadium and lead.

[Current radiation status of the ecosystem of the Lake Bolshoi Igish situated along the axial part of the East-Urals radioactive trace].
Data on the current radioecological status of lake Bolshoi Igish in the Middle Ural are presented in the paper. The lake is situated on the central axis of the East-Urals radioactive trace which was formed as a result of the 1957 nuclear accident at the Mayak Production Association. The distribution of 90Sr and 137Cs in the major components of the water basin is shown. Seasonal dynamics of the specific activity of radionuclides in water and in bottom deposits has been investigated. The current community of the higher water plant species has been studied. The paper discusses the concentration of 90Sr and 137Cs in the macrophyts of lake Bolshoi Igish depending on their species.

[Current radioecological conditions of Malyĭ Igish lake located on the axial part of the East-Urals radioactive trace].
The paper presents data on the current radioecological situation at Lake Maly Igish located on the axial part of the East-Urals radioactive trace formed after the 1957 accident at the Mayak PA. The chemical composition of the water and bottom deposits, as well as the distribution of 90Sr, 137Cs, and of the microelements in the main components of the water reservoir were studied. The current species composition of higher aquatic plants and of the species-specific concentration of 90Sr and of 137Cs was identified.

[Migration characteristics and forms of 90Sr and 137Cs observed in the bottom sediments of certain lacustrine ecosystems on the East Urals Radioactive Trace].
The research findings summarized in the paper include data on the radioecological conditions in two lakes (Large Ighish and Small Ighish) located on the East Urals Radioactive Trace. The focus of the study was on the chemical composition of water and bottom sediments, as well as on the specific features of 90Sr and of 137Cs distribution and the forms in which they occur in silts. Coefficients of radionuclide accumulation in the bottom deposits of the lakes of interest were estimated. A conclusion was drawn about the dependences influencing radionuclide distribution by layers of the lake bottom sediments.

[90Sr and 137Cs in higher aquatic plants of some water basins on the East-Urals Radioactive Trace: species features of radionuclide concentration].
The paper summarizes the results from radioecological studies of a number of water basins located on the East-Urals Radioactive Trace (EURT), as exemplified by the lakes Large Ighish, Small Ighish and Shablish which are included in the medium-distance and remote zone of the EURT. The lake Misyash which is situated in the opposite direction from the release vector and has been only contaminated due to global fallouts has been used as a control water basin. The current species composition of the high aquatic plants and species-specific concentration of 90Sr and 137Cs in them was studied, also, the radionuclide accumulation and discrimination coefficients were estimated.
