- Abstract
This paper presents research data on water contamination levels of artificial radionuclides and heavy metals in Karabulak Creek at the Semipalatinsk Test Site. The uranium isotopic composition has been studied (
235 U and238 U). Priority contaminants and the most 'contaminated' sections of the Karabulak creek were identified, and water quality-related indicators were also estimated. The environmental situation around Karabulak Creek at the «Degelen» site—at which underground nuclear tests have been conducted—was found to be unique and attributed to the combined effect of man-made radiation and natural factors and, in particular, to geochemical features of the region.

This paper presents the determination method of the exact geographical coordinates of aboveground nuclear tests (NT) epicenters based on the radioecological study results the example of the Semipalatinsk Nuclear Test Site. By testing the NT Epicenter software for determining the exact geographic coordinates of the NT centers, it was established that it is indeed possible to determine the exact coordinates of most of the aboveground NTs. Their locations are currently determined by the presence are currently determined by the presence of technogenic disturbance of the soil surface in the area of the alleged epicenter (the presence of a crater), as well as by comparing maps of radioactive contamination and a space image. The accuracy of the precise coordinates of the NT is highly dependent on the density of the auxiliary grid: the smaller the pitch of the auxiliary grid, the higher the accuracy of the NT epicenter.

This article presents research findings on
3 H in abiotic environmental compartments, specifically, the 'water-soil-air' system. All of the research areas are located within the Semipalatinsk Test Site (STS): the perimeter of the 'Degelen' site, the riverside zone of the Shagan river and the 'background' area–the southeastern part of the STS (SEP). As research progressed, numerical values of3 H and its species were revealed in various environmental compartments. The presence of3 H was registered not only in underground nuclear test locations but also in the 'background' area–SEP. Maximum3 H tritium concentrations in the water were detected at the 'Degelen' site (up to 57000±5000 Bq/kg) and the Shagan riv (up to 61500±6000 Bq/kg), in the air of the 'Degelen' site (up to 56±11 Bq/m3 ), in the soil of the 'Degelen' site (up to 5170±500 Bq/kg) and the Shagan riv (4100±400 Bq/kg) in the free water, at SEP (up to 1710±170 Bq/kg) in the organic constituent. Based upon all of the findings,3 H was found to be readily distributed in abiotic environmental compartments depending on certain conditions. Research suggests that water plays a key role in3 H migration processes in the natural system of interest. The second most but equally important constituent is soil and microorganisms of plant and animal origin living there. These assumptions are indirectly proven by research findings that show the HTO and HT air concentration dynamics depending on the sampling location. [ABSTRACT FROM AUTHOR]- Published

This paper describes the dynamics of
137 Cs accumulation and its concentration ratio as well as that of some stable elements in the body, shell, gastrointestinal tract and albumin gland of a particular species of snail (terrestrial gastropod), namely the Giant African snail (Lissachatina fulica), after the long-term ingestion of contaminated forage and/or soil. The activity concentration of137 Cs in the their bodies increased over the first 40 days of the experiment, after which the increase in the activity of this radionuclide significantly reduced. The distribution of137 Cs in the body of a snail decreases as follows: gastrointestinal tract ˃ body = albumin gland ˃ shell. It was found that the contribution of soil towards the contamination of their bodies by137 Cs is far less than that of forage. Although the biological availability of Pb and U in forage is one order of magnitude higher than in soil, the main contribution to the contamination of snails originates from soil.

Актуальность работы обусловлена необходимостью получения современных данных о концентрации химических элементов в системе "вода-почва-растения" на припортальном участке штольни 504 площадки "Дегелен" бывшего Семипалатинского испытательного полигона. В период весеннего половодья возможен вынос элементов за пределы площадки штольни 504. Цель: изучение пространственного распределения химических элементов в системе «вода-почва-растения» в водотоке штольни 504. Для достижения данной цели были поставлены следующие задачи: 1) определить уровни концентрации химических элементов в воде; 2) изучить уровни концентрации химических элементов в почве; 3) выявить особенности накопления химических элементов в растениях штольни 504. Методы. Элементный состав воды определялся методами масс-спектрометрии с индуктивно-связанной плазмой (Elan 9000 "Perkin Elmer SCIEX"), атомно-эмиссионной спектрометрии с индуктивно-связанной плазмой ("iCAP 6300 Duo" Thermo Scientific). Анализ таких показателей, как общая минерализация, содержание сульфатов, гидрокарбонатов, хлоридов, кальция, магния и натрия, проводился титриметрическими, колориметрическими, потенциометрическими методами в соответствии с ГОСТ. Результаты. Анализ данных, полученных по воде, показал высокое содержание таких элементов, как Li, Be, Al, Mn, Zn, Rb, Sr, Cd, Cs, La, Ce, U, среднее содержание которых в несколько раз превышает показатель кларка в подземных водах аридного климата (сульфатные воды). Также для воды замечено превышение предельно допустимых уровней для таких элементов, как Be (2800 ПДК), Mn (260 ПДК), Al (76 ПДК), U (70 ПДК) и Cd (50 ПДК). По последним данным выявлено, что содержание таких элементов, как Li, Be, Al, в воде увеличилось в 2 раза, тогда как Co, Ni и Cu - в десятки раз. Пространственное распределение исследуемых элементов в почве штольни 504 неоднородно, большая часть элементов концентрируется в грунте севернее русла водотока. На данном участке выявлено повышенное содержание таких элементов, как Be, Mn, Cu, Zn, Мо, Cd, Cs, Pb и U, превышающих показатель кларка литосферы. Индекс превышения значения кларка литосферы составил для концентрации урана 1000 раз. Сравнение полученных данных на загрязненных участках со значением предельно-допустимых концентраций химических элементов для почвы выявило превышение у Pb (26 ПДК), Mn и Cu (9 ПДК). Химический состав воды и почвы штольни 504 является уникальным по содержанию редкоземельных элементов. Среднее содержание РЗЭ в воде в тысячу раз превышает показатель кларка в подземных водах аридного климата и подземных водах СИП. Замечено превышение предельно допустимого уровня концентрации для самария в воде. Характерным является преобладание группы легких РЗЭ с ярко выраженной церий-лантановой специализацией. Для большинства видов растений штольни 504 на загрязненном участке выявлено повышенное содержание Be, Сd, Cs, Pb, U и ряда РЗЭ. Концентрация исследуемых элементов в таких видах растений, как тростник и вейник, на сравниваемых участках менялась незначительно, что, видимо, обусловлено наличием физиолого-биохимических механизмов, препятствующих их поступлению. Исходя из вышеизложенного, можно сделать вывод, что пространственное распределение элементов на площадке штольни 504 связано, прежде всего, с выносом химических элементов штольневыми водами. В воде штольни 504 выявлено порядка десяти элементов, превышающих значения кларка и предельно допустимые уровни. Relevance of the research is caused by the necessity of obtaining up-to-date data on concentrations of chemical elements in the "water- soil-plant" system on the near-entry spot of tunnel 504 of "Degelen" site at the former Semipalatinsk Test Site. During flooding in spring, elements may be carried out beyond tunnel 504. The main aim of the research is to study spatial distribution of chemical elements in the "water-soil-plant" system in the streamflow of tunnel 504. To achieve this goal, the following tasks were set: 1) determine concentration levels of chemical elements in water; 2) study concentration levels of chemical elements in soil; 3) identify features of chemical elements accumulation in plants of tunnel 504. Methods. The ultimate composition of water was determined by inductively-coupled plasma mass-spectrometry (Elan 9000 "Perkin Elmer SCIEX"), inductively-coupled plasma atomic emission spectrometry ("iCAP 6300 Duo" Thermo Scientific). The analysis of such indicators as total mineralization, the content of sulfates, hydrocarbonates, chlorides, calcium, magnesium and sodium was carried out using titrimetric, colorimetric, potentiometric techniques in accordance with GOST. Results. The analysis of the data obtained for water showed a high content of such elements as Li, Be, Al, Mn, Zn, Rb, Sr, Cd, Cs, La, Се, U the average content of which exceeds the clarke several times for groundwater of the arid climate (sulfate water). The excess of maximum permissible levels of such elements as Be (2800 MPC), Mn (260 MPC), Al (76 MPC), U (70 MPC) and Cd (50 MPC) has been registered for water. According to the latest data, the content of such elements as Li, Be, Al in water was found to increase by 2 times whereas that of Co, Ni and Cu - by dozens of times. Spatial distribution of elements of interest in soil of tunnel 504 is non-uniform. Most of elements are concentrated in soil to the north of the streamflow bed. An elevated content of such elements as Be, Mn, Cu, Zn, Мо, Cd, Cs, Pb and U was detected in this area exceeding the clarke of lithosphere. The high index of lithosphere clarke value excess was found for uranium concentration (1000 times). Comparison of findings for contaminated areas with values of maximum permissible concentrations of chemical elements in soil showed the excess for Pb (26 MPC), Mn and Cu (9 MPC). Chemical composition of water and soil of tunnel 504 is unique by the content of rare-earth elements. The average content of REE in water exceeds the clarke by thousand times in ground water of the arid climate and STS ground water. The excess of the maximum permissible concentration level of samarium was observed in water. Predominance of light REE is characteristic, with a pronounced cerium-lanthanum feature. This fact shows that metals in water originate from natural sources. For most plant species of tunnel 504 an elevated content of Be, Сd, Cs, Pb, U and a number of REE was detected in the contaminated area. Concentrations of elements of interest in such plant species as reed and bluejoint in areas being compared, varied insignificantly which is apparently attributed to some physiological and biochemical mechanisms that impede the intake. Based on the above, one can conclude that spatial distribution of elements at tunnel 504 is first of all related to chemical elements carried out by tunnel water. About ten elements exceeding clarke values and maximum permissible levels were detected in water of tunnel 504.

Актуальность данной работы обусловлена необходимостью расширения методов комплексных экологических исследований для оценки качества объектов окружающей среды малых населенных пунктов. Изучение элементного состава пылеаэрозольных выпадений даст наиболее полную картину о состоянии качества основных природных компонентов. Аэрозоли воздуха представляют собой сложную дисперсную систему, включающую в себя частицы размером менее 10 микрон. Эти частицы имеют как природное, так и техногенное происхождение: мелкодисперсные пылевые частицы почвы, растений, микроорганизмы, сажа, зола, составные части дымовых выбросов котельной, промышленности и т. д. Атмосферный воздух небольших населенных пунктов остается малоизученным, отсутствуют систематические данные о химическом составе атмосферных взвесей, в связи с чем и определяется актуальность данной работы. Цель: определить элементный состав твердой фазы снегового покрова малого населенного пункта Долонь. Объекты: пылеаэрозольные выпадения, твердые частицы аэрозолей воздуха, снеговой покров, уголь и зола. Методы: масс-спектрометрический и атомно-эмиссионный с индуктивно-связанной плазмой. Результаты. Изучен элементный состав снеготалой воды и твердой фазы снега. Для определения степени летучести химических элементов рассчитан их коэффициент обогащения из угля в золу. Определены основные зоны с повышенным содержанием тяжелых металлов в пылеаэрозольных выпадениях. В снеговом покрове исследуемой территории выявлена группа элементов с высокой миграционной способностью. Построены карты загрязнения снегового покрова населенного пункта Долонь с выделением участков (ореолов загрязнений) с повышенным содержанием исследуемых групп элементов. The relevance of this work is caused by the need to expand the methods of complex environmental studies to assess the quality of environmental objects in small communities. The study of the elemental composition of dust and aerosol depositions will provide the most complete picture of the quality status of the main natural components. Air aerosols are a complex dispersed system that includes particles smaller than 10 microns. These particles have both natural and man-made origin: finely dispersed dust particles of soil, plants, microorganisms, soot, ash, components of smoke emissions from boiler houses, industry, etc. Atmospheric air of small settlements remains poorly studied, there are no systematic data on the chemical composition of atmospheric pollutants, and therefore the relevance of this work is determined. The aim of the research is to determine the elemental composition of the solid phase of the snow cover of a small settlement Dolon. Objects: dust-aerosol deposition, particulate matter of air aerosols, snow cover, coal and ash. Techniques: mass spectrometric and atomic emission with inductively coupled plasma (MS-ISP, OES-ISP) Results. The elemental composition of snow melt water and solid phase of snow was studied. To determine the degree of volatility of chemical elements their coefficient of enrichment from coal to ash was calculated. The main zones with increased content of heavy metals in dust and aerosol depositions were determined. In the snow cover of the investigated territory a group of elements with high migratory capacity was revealed. Maps of the snow cover pollution of the Dolon settlement were constructed with identification of areas (halos of pollution) with increased content of the studied groups of elements.

Data on the transfer of artificial radionuclides from the environment to the food supply is necessary for internal dose assessment. There is a necessity for expanding and improving the available information on these factors in order to make better dose models for specific scenarios. This paper describes the results of a field experiment with broiler chickens on the transfer factor (F
f ) and concentration ratio (CR ) for the long-term intake of241 Am and137 Cs with grass meal and soil. The broilers were divided into two groups, each group had nine subgroups and each subgroup had three broilers. The radionuclide concentrations in the feed and the thigh muscle, thigh bone, and liver of 54 broilers divided between the grass meal and soil groups were evaluated by gamma spectrometry for 241Am and 137Cs. The duration of feeding with "contaminated" sources ranged between 1–70 days. The equilibrium stage of241 Am in muscle and bone occurs on the 1st and 40th day, respectively; for137 Cs in muscle– 30th days of intake and for liver and bone– 7th days. For241 Am, the liver did not reach equilibrium stage during the 70 days of intake. Ff of137 Cs in the "forage-muscle" and "soil-muscle" systems were determined as 1.9±0.3 and 0.18±0.05; Ff of241 Am in the "soil-muscle" system was—7.5×10−5 . [ABSTRACT FROM AUTHOR]- Published
