Актуальность исследования. Болезнь Кашина-Бека (уровская болезнь) является классическим примером класса эндемических болезней. Однако, в отличие от других болезней, для данного заболевания до сих пор не установлена причина возникновения. В настоящее время в научной литературе обсуждается более 20 теорий и гипотез, объясняющих этиологию и факторы болезни. Приоритетной теорией является биогеохимическая, согласно которой возникновение и течение болезни зависит от фактора окружающей среды (недостаток/избыток химических элементов или соединений). В связи с этим изучение химического состава компонентов окружающей среды в районе распространения болезни Кашина-Бека является актуальным. Цель: оценка геохимических особенностей компонентов природной среды на территории юго-восточного Забайкалья - района распространения болезни Кашина-Бека. Объекты: компоненты природной среды - почва, донные отложения, природные воды (поверхностные, подземные), солевые отложения питьевых вод, керн годовых колец деревьев, листья тополя, лишайники, мхи, полынь, картофель, волосы детей, кости свиньи домашней. Методы: элементный состав изученных компонентов природной среды определен методами инструментального нейтронно-активационного анализа и масс-спектрометрии с индуктивно связанной плазмой. Обработка полученных данных включала нормирование содержания химических элементов относительно фоновых показателей (кларк ноосферы, вода оз. Байкал) и расчет индикаторных отношений. Результаты. Изучено содержание 26 (по данным инструментального нейтронно-активационного анализа) и 62 (по данным массспектрометрии с индуктивно связанной плазмой) химических элементов в 13 компонентах природной среды. В элементном составе всех изученных компонентов выявлена региональная геохимическая ассоциация (Zn-Pb-Ba-Sb-As-Bi-Au), связанная с особенностями металлогении района. Для проведения будущих исследований наиболее информативными компонентами являются природные воды, костная ткань, волосы детей. Наиболее контрастная геохимическая специализация окружающей среды формируется в населенных пунктах, где по литературным данным наблюдались максимальные уровни заболеваемости болезни Кашина-Бека. Этиология болезни носит многофакторный характер: в развитии заболевания большую роль играют природные условия, что приводит к дисбалансу элементного состава компонентов окружающей среды и, соответственно, организма человека. The relevance of the research. Kashin-Beck disease, or Urov disease, is a classic example of endemic diseases. However, unlike other diseases, the cause of this one has not yet been determined. Currently, the scientists discuss more than 20 theories and hypotheses that explain its etiology and factors. The priority theory is the biogeochemical one, according to which the occurrence and history of the disease depends on the environmental factor (lack/excess of chemical elements or compounds). In this regard, the study of the environmental geochemistry in the area of Kashin-Beck disease is relevant. The main aim of the research is to assess the environmental components geochemical features in the territory of south-eastern Transbaikalia, area of Kashin-Beck disease distribution. Objects: environmental components - soil, bottom sediments, natural waters (surface, underground), drinking water salt sediments, core of tree rings, poplar leaves, lichen, moss, wormwood, potato, children's hair, bones of domestic pig. Methods: instrumental neutron activation analysis and inductively coupled plasma mass spectrometry for detection of chemical composition of environmental components; processing of the obtained data included normalization of chemical elements content relative to background values (the noosphere clarke, water of Lake Baikal) and calculation of indicative ratios. Results. The content of 26 (instrumental neutron activation analysis) and 62 (inductively coupled plasma mass spectrometry) chemical elements in 13 environmental components was studied. In the element composition of all the studied components, a regional geochemical association (Zn-Pb-Ba-Sb-As-Bi-Au) was identified, associated with the features of the regional metallogeny. For future research, the most informative components are natural waters, bone tissue, and children's hair. The most contrasting geochemical specialization of the environment is formed in settlements where, according to literature data, the maximum incidence of Kashin-Beck disease is observed. The disease etiology is multifactorial: natural conditions play an important role in the development of the disease, which leads to an imbalance in the element composition of the environmental components and, respectively, the human body.

Актуальность. Антропогенная деятельность, в том числе добыча полезных ископаемых, сопряжена с загрязнением окружающей среды и накоплением отходов производства. Предотвращение и ликвидация наблюдаемых при этом негативных воздействий предполагает целый ряд мероприятий, первым из которых является оценка их влияния на природную среду. В свою очередь, она невозможна без знания фонового состояния компонентов окружающей среды, что и определило актуальность исследования. Цель работы: установить влияние эколого-геохимических факторов на уровни накопления химических элементов в эпифитных лишайниках, используемых в качестве индикаторов антропогенного влияния на окружающую среду; определить фоновые концентрации элементов в лишайниках для последующей оценки воздействия процессов добычи и транспортировки полезных ископаемых. Методы исследования: методы математической статистики, ландшафтно-геохимический метод, методы определения химического состава компонентов окружающей среды (нейтронно-активационный). Результаты. Установлено, что химический состав эпифитных лишайников отражает природные геохимические особенности коренных пород и почвенного покрова территории их произрастания. Полученные данные свидетельствуют о достаточно близких уровнях накопления, укладывающихся в доверительный интервал определений таких 16 элементов, как La, Ce, Sm, Eu, Tb, Yb, Lu, Hf, Th, Sc, Fe, Co, Ca, Na, Rb, Cs, а также группы из 12 элементов: Cr, Zn, As, Br, Sr, Ag, Sb, Ba, Nd, Ta, Au, U, для которых наблюдаются более значимые различия в оценке их средних для каждого из изученных фоновых участков. Рекомендовано в качестве регионального фона для юга Западной Сибири использовать элементный состав эпифитных лишайников Томского района, который характеризуется незначительным влиянием промышленных предприятий и отсутствием каких-либо выявленных геохимических аномалий коренных пород и подстилающей поверхности. The relevance of the research. For comparison of data obtained in studies of polluted urban areas, it is necessary to have background levels of concentrations of the identified chemical elements in environment. The main aim of the study is to evaluate the influence of ecological and geochemical factors on the levels of accumulation of chemical elements in epiphytic lichens collected in areas practically unaffected by anthropogenic activity. The methods used in the study: the method of instrumental neutron activation analysis (data on 28 chemical elements in the ash of lichens); statistical analysis. The results. It was determined that the lichen chemical composition reflects natural geochemical features of bed rocks and soils in the territory of their growing. The data indicate a fairly close levels of accumulation, which is defined as the confidence interval of defining 16 elements such as La, Ce, Sm, Eu, Tb, Yb, Lu, Hf, Th, Sc, Fe, Co, Ca, Na, Rb, Cs, and group of 12 elements: Cr, Zn, As, Br, Sr, Ag, Sb, Ba, Nd, Ta, Au, U, for which there are more significant differences in the assessment of their average for each of the background regions studied. Elemental composition of the epiphytic lichens on Tomsk region was recommended as regional background for Siberia. This area is characterized by negligible industrial influence and by absence of geochemical anomalies of bed rocks and underlying surface.

EPIPHYTIC lichens , *BIOGEOCHEMICAL cycles , *CHEMICAL elements , *MASS spectrometry - Abstract
The work represents the data of the research of the chemical composition of epiphytic lichens Evernia mesomorpha (L.), growing around the tailings of a former gold-polymetallic deposit (Kemerovo region. Western Siberia, Russia). The lichen samples were collected from trees according to a radial net (20 samples in total). The concentrations of chemical elements in the dry lichen matter were determined by the mass spectrometry with inductively coupled plasma. The results obtained were compared with the concentrations of chemical elements in lichens of the same specie collected in a nature reserve of Crimea peninsula. This reserve is considered as a reference area which is practically not subjected to anthropogenic impact. The ratios of the concentrations of chemical elements in the lichens from the tailings area to the reference concentrations of the Crimea peninsula were considered as concentration coefficients (Cc). As a result, we found high concentrations of Mn(4), As(4.5), Ag(15.5), Sb(40), Ba(87), Eu(2,5), Hg(19), Pb(7), Bi(5), and U(2), which indicate the geochemical specialization of the tailings area. The concentrations of Au (0.014 mg/kg) and Se (3.5 mg/kg) were only found in the samples from the tailings area and were lower the detection limit in the reference area samples. For most chemical elements we found close concentrations within the confidential interval: K, Li, Na, Mg, Al, P, K, Ti, V, Cr, Co, Cu, Ge, Sr, Ir, Cr, Nb, Mo, Cd, Sn, Cs, La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, Ib, Lu, Hf, Ta, W. These data may testify on the global accumulation factor in the atmosphere, for example, general dust transport of mineral matter of soils and rocks of nanoparticle size. The concentrations of B, Ca, and Ni were found in lower concentrations in the lichens of the tailings area (Cc ranges from 0,2 to 0.5). The research confirms good biomonitoring properties of epiphytic lichens and allows judging about the geochemical specialization of the tailings of the gold-polymetallic deposit.

The research represents the results of the study of metals in the leaves of Betula pendula R. in the settlement Ursk around the tailings of the former gold-polymetallic deposit located in Kemerovo region in the south of Western Siberia. 17 leaf samples were collected by the radial net with the step of 150-200 meters. The concentrations of chemical elements in the dry leaf matter were determined by the ICP-MS method. The concentrations of Hg, Ni, Cd, Pb, Zn, Ag, Sb, Ba, Co, and As in the leaves from 3 to 11 times exceed the background (reference) values. Close to the wastes of initial ore at the western side of the tailings, orthomorphic biogeochemical halos of Hg, Pb, As, Sb and Ag are localized. Close to the rock dump from the oxidation zone in the eastern side of the tailings, polyelemental halos of Zn and Cd are localized. The halos of Hg, Pb, As and Sb are also observed in the "cone region" in the southern swamped part of the tailings. Therefore, these elements are active migrants. Additive indexes on the concentration ratio of essential and toxic metals in the leaves were calculated. By the data of electron microscopy of the external leaf surface (close to the dumps), we found mineral phases of Ba (BaSO4), Hg (HgSe), Ag, Pb, Sb and Zn in large quantities. These data testify on the predominant aerogenic pollution of this territory. Thus, the leaves of Betula pendula R. are confirmed to be accumulators of metals, and the tree specie itself is an effective biomonitor. The results of this work may be used for the biogeochemical monitoring of the territories around tailings of mining enterprises with polymetallic specialization. [ABSTRACT FROM AUTHOR]

ENVIRONMENTAL impact analysis , *METAL tailings , *EPIPHYTIC lichens , *TUBE lichens , *HYPERGENESIS (Geology) , *SULFIDE ores - Abstract
The aim of this work is the research of elemental composition of epiphytic lichens growing in the areas of the influence of tailings from mining and the detection of indicative pollutants entering the environment in these regions. The samples of lichens of two species Hypogymnia physodes and Evernia mesomorpha were collected in the summer 2015 in the territories adjacent to the Ursk and Komsomolsk tailings in Kemerovo region (Russia). The concentrations of chemical elements in 49 samples were determined by the mass spectrometry with inductively coupled plasma. The results showed higher concentrations of Sb (Cc = 17,4), As (3,3), and Hg (2,5) in the lichens from the Komsomolsk tailings in comparison with the local background values. Maximal concentrations were found in the northeastern direction from the tailings - near the lake formed after the mined carrier, where the sulfides have been transformed into other mineral forms due to the hypergenesis process. The chemical elements, containing in these minerals, migrate and pollute all environmental components. The ecological-geochemical specificity of the Ursk tailings consists in the high concentrating by lichens of Ba (Cc = 62), Sb (22), Hg (16), Ag (13,6), Mn (10), Pb (9,3) and As (4,1). This specificity is determined by the waste composition of the Ursk tailing dump formed from the cyanidation of Hg-containing sulfide ores of the Novo-Urskoe deposit. The results of this research testify that the elemental composition of lichens is directly related to the specificity of the matter composition of the tailings from mining and ore processing.
