“…Owing to the heterogeneity of source area, facial differences, varied influence of syn-depositional volcanism, the direct comparison of the uranium concentrations in coals of different ranks does not reach correct conclusions [2]. However, the relationship of uranium concentration to coal ranks and coal-forming periods represent the geochemical habit of uranium-organic affinity.…”

“…Uranium connately and ubiquitously occurs in coal. Thus, coal combustion is considered as one source of radioactive material in the environment [2][3][4][5]. Though it is controversial, the radiation doses from atmospheric emission of a coal-fired power plant were considered to be greater than those from a nuclear plant of comparable size [6,7].…”

Due to its environmental and resource impacts, the geochemistry of uranium in coal is of both academic and practical significance. In order to give a comprehensive summary about the geochemistry of uranium in coals, the abundance, distribution, and modes of occurrence of uranium in Chinese coals were reviewed in this paper. Although some coals from southwestern and northwestern China are significantly enriched in uranium, the common Chinese coals are of a comparable uranium concentration to the world coals. The roof and floor rocks, and parting of coalbeds, or coal benches that are close to the surrounding rock are favorable hosts for uranium in one coalbed. The uranium concentrations in coals of different ages decrease in this order, e.g., Paleogene and Neogene > Late Permian > Late Triassic > Late Carboniferous and Early Permian > Late Jurassic and Early Cretaceous > Early and Middle Jurassic. Uranium in Chinese coals is mainly associated with organic matter, and is correspondingly enriched in subbituminous coal and lignite.

“…It is known that coals sometimes include high contents of natural radioactive elements (U, Th, and their decay products) and, in some cases, concentrate considerable amounts of the uranium [12,13]. The four highest 40 K activity concentration are 808, 561, 561 and 541 Bq kg −1 , which were found in soil samples collected from the Soğanlıy-örük, Beycuma, İsabeyli and Alpaslan respectively.…”

“…Under the local sources we mean the private housing, where coal can be used for heating. According to [15], in coal radioactive and rare earth elements contain as impurity; these elements sorb during the burning at the fine fractions of solid particles and come to the atmospheric air. Earlier we [16] detect high concentrations of U, Th and rare earth elements in the samples from the localities of Kozhevnikovsky district.…”

Local heating plants are the main pollution source of rural areas. Currently, there are few studies on the composition of local heating plants emissions. The article deals with the research results of air pollution level with solid airborne particles in the vicinity of local gas-fired heating plants of some districts of Tomsk region. The snow sampling was conducted for the purpose of solid airborne particles extraction from snow cover. The content of 28 chemical elements (heavy metals, rare earth and radioactive elements, aurum, argentum, bromine) in the samples was detected using instrumental neutron activation analysis. The mercury content was determined by the flameless atomic absorption. The results have shown that the dust load value corresponds to low pollution level and 3,5 times exceeds the background value. It was detected, the content of studied elements exceeds the baseline data, and level of pollution with these elements corresponds to the average pollution level. It is suggested, the income of solid airborne particles containing these elements is connected both with emission of gas-fired heating plant, and local and trans-border sources.
