    The aim of this study was to investigate the distribution of some toxic elements in topsoil and subsoil, focusing on the identification of natural and anthropogenic element sources in the small region of rare As–Sb–Tl mineralization outcrop and abandoned mine Allchar known for the highest natural concentration of Tl in soil worldwide. The samples of soil and sediments after total digestion were analyzed by inductively coupled plasma–mass spectrometry (ICP–MS) and inductively coupled plasma–atomic emission spectrometry (ICP–AES). Factor analysis (FA) was used to identify and characterize element associations. Six associations of elements were determined by the method of multivariate statistics: Rb–Ta–K–Nb–Ga–Sn–Ba–Bi–Li–Be–(La–Eu)–Hf–Zr–Zn–In–Pd–Ag–Pt–Mg; Tl–As–Sb–Hg; Te–S–Ag–Pt–Al–Sc–(Gd–Lu)–Y; Fe–Cu–V–Ge–Co–In; Pd–Zr–Hf–W–Be and Ni–Mn–Co–Cr–Mg. The purpose of the assessment was to determine the nature and extent of potential contamination as well as to broadly assess possible impacts to human health and the environment. The results from the analysis of the collected samples in the vicinity of the mine revealed that As and Tl elements have the highest median values. Higher median values for Sb are obviously as a result of the past mining activities and as a result of area surface phenomena in the past. - Highlights: • Soil and river sediments were analyzed from Sb–As–Tl Allchar locality. • An increased content of certain toxic elements for environment was determined. • Highest As and Tl contents are obtained in the close vicinity of Allchar mine. • River sediments portray 160 times higher content of Sb than EU values. • The results classify Allchar as probably the highest natural Tl-deposit worldwide.

  7. Trip report: European Communities 1989 International Conference on Decommissioning of Nuclear Installations, Brussels, Belgium, October 24-27, 1989

    SciTech Connect (OSTI)

    Rankin, W.N.


    The European community is conducting research on the decommissioning of nuclear installations. The prime objective is to develop effective techniques to ensure the protection of man and his environment against the potential hazards of nuclear installations that have been shut down. The results of the 1979--1983 research program were presented in a conference held in Luxembourg. This program was primarily concerned with decommissioning nuclear power plants. The 1984--1988 program was extended to all types of nuclear installations. Fuel fabrication, enrichment and reprocessing plants, and research and development facilities having fulfilled their useful purposes are also awaiting decommissioning. This Program has produced numerous scientific and technical achievements. Great progress has in particular been achieved in the reduction of metal waste arising from decommissioning, due to advances in areas such as the development of aggressive decontamination procedures and of techniques for melting and recycling low-level radioactive waste metal.

    This paper discusses the international aspects of the petroleum industry. Most who work in the industry agree that the possibilities for huge are found largely in international regions. Something that is helping fuel that possibility is the way countries are increasingly opening their doors to US oil industry involvement. Listed in this paper is a partial list of the reported projects now underway around the world involving US companies. It is not intended to be comprehensive, but rather an indication of how work continues despite a general lull atmosphere for the oil industry. These include Albania, Bulgaria, Congo, Czechoslovakia, Dominican Republic, Ethiopia, Ireland, Malta, Madagascar, Mongolia, Mozambique, Nigeria, Panama, Paraquay, and Senegal.

  10. The EURATOM Supply Agency

    SciTech Connect (OSTI)

    Lightner, J.


    With the coming liberalization of trade and industry within the European Community (EC) and a more centrally-coordinated EC external trade policy, it is timely to ask if in the 1990s there will be any significant changes in the commercial relations between the EC and non-EC companies trading in nuclear fuel. The key vehicle for implementing any change of policy would probably be the European Atomic Energy Community (EURATOM) Supply Agency in Brussels, which is charged under the EURATOM Treaty with overseeing the equitable supply of nuclear fuel to and among EC companies. The EURATOM Supply Agency (the Agency) is a signatory to almost all EC-company contracts for transactions that occur on the territory of the Community, which includes Belgium, Denmark, France, the Federal Republic of Germany (FRG), Great Britain, Greece, Ireland, Italy, Luxembourg, the Netherlands, Portugal, and Spain. During the 1980s, the Supply Agency has rarely tried to influence the commercial decisions of EC member companies. The nuclear fuel industry has largely perceived the Agency as an administrative office that registers contracts and maintains relations with some outside governments, particularly Australia, Canada, and the USA. However, in 1988 the Agency began to have a more direct commercial impact when it reviewed the practice-previously conducted routinely by the EURATOM Safeguards Directorate in Luxembourg at the request of EC-member companies-of swapping safeguards obligations on equivalent quantities of uranium at different locations (flag swapping). The Agency`s actions inhibiting flag swaps, as well as a related de facto policy restricting material swaps of Southern African uranium, caused it to be viewed as obstructive by some EC companies. During 1989 the discussion about flag swaps and swaps involving South African and Namibian uranium has subsided, and a far-reaching discussion has arisen about EC trade policy in general.

    McKay, K.L.; Gow, D.; Brown, C.; Christophersen, K.; Gaylord, E.


    The African sub-continent (Sub-Saharan Africa) is a vast continent of mangroves and deserts, rainforests, mountains and, miles upon thousands of miles of flat wooded plains. It is a continent whose people rely directly on its basic natural resources--land, water, soils, animals and vegetation--for their day-to-day subsistence and development. The effects of environmental degradation have taught bilateral and multilateral agencies, non-governmental organizations (NGOs), and national governments harsh lessons about the critical importance of natural resources management to food security and development. The report examines the role of NGO's as resource stewards and explores the relationship between NGO's and donors in the environmental field, with particular reference to experiences from the Natural Resources Management Support Project for Africa and from the literature. Practical guidelines for enhancing the effectiveness of donor- collaboration are suggested. Annexes present case studies of Cameroon, Madagascar, and Mali.

    Beredjick, N.


    The United Nations implements technical cooperation projects in developing countries through its Department of Technical Cooperation for Development (DTCD). The DTCD is mandated to explore for and develop natural resources (water, minerals, and relevant infrastructure) and energy - both conventional and new and renewable energy sources. To date, the United Nations has been involved in over 30 geothermal exploration projects (completed or underway) in 20 developing countries: 8 in Africa (Djibouti, Ethiopia, Kenya, Madagascar); 8 in Asia (China, India, Jordan, Philippines, Thailand); 9 in Latin America (Bolivia, Chile, El Salvador, Honduras, Mexico, Nicaragua, Panama) and 6 in Europe (Greece, Romania, Turkey, Yugoslavia). Today, the DTCD has seven UNDP geothermal projects in 6 developing countries. Four of these (Bolivia, China, Honduras, and Kenya) are major exploration projects whose formulation and execution has been possible thanks to the generous contributions under cost-sharing arrangements from the government of Italy. These four projects are summarized.

  15. Tracing the HIV-1 subtype B mobility in Europe: a phylogeographic approach

    Leitner, Thomas; Paraskevis, D; Pybus, O; Magiorkinis, G; Hatzakis, A


    The prevalence and the origin of HIV-1 subtype B, the most prevalent circulating clade among the long-term residents in Europe, have been studied extensively. However the spatial diffusion of the epidemic from the perspective of the virus has not previously been traced. In the current study we inferred the migration history of HIV-1 subtype B by way of a phylogeography of viral sequences sampled from 16 European countries and Israel. Migration events were inferred from viral phylogenies by character reconstruction using parsimony. With regard to the spatial dispersal of the HIV subtype B sequences across viral phylogenies, in most of the countries in Europe the epidemic was introduced by multiple sources and subsequently spread within local networks. Poland provides an exception where most of the infections were the result of a single point introduction. According to the significant migratory pathways, we show that there are considerable differences across Europe. Specifically, Greece, Portugal, Serbia and Spain, provide sources shedding HIV-1; Austria, Belgium and Luxembourg, on the other hand, are migratory targets, while for Denmark, Germany, Italy, Israel, Norway, the Netherlands, Sweden, Switzerland and the UK we inferred significant bidirectional migration. For Poland no significant migratory pathways were inferred. Subtype B phylogeographies provide a new insight about the geographical distribution of viral lineages, as well as the significant pathways of virus dispersal across Europe, suggesting that intervention strategies should also address tourists, travellers and migrants.

  16. Quarterly coal report, January--March 1993

    SciTech Connect (OSTI)

    Not Available


    The United States produced 242 million short tons of coal in the first quarter of 1993, a decrease of 6 percent (14 million short tons) from the amount produced during the first quarter of 1992. The decrease was due to a decline in production east of the Mississippi River. All major coal-producing States in this region had lower coal production levels led by West Virginia, which produced 5 million short tons less coal. The principal reasons for the overall drop in coal output compared to a year earlier were: A decrease in demand for US coal in foreign markets; a slower rate of producer/distributor stock build-up; and a drawn-down of electric utility coal stocks. Distribution of US coal in the first quarter of 1993 was 10 million short tons lower than in the first quarter of 1992, with 5 million short tons less distributed to both electric utilities and overseas markets. The average price of coal delivered to electric utilities during the first quarter of 1993 was $28.65 per short ton, the lowest value since the first quarter of 1980. Coal consumption in the first quarter of 1993 was 230 million short tons, 4 percent higher than in the first quarter of 1992, due primarily to a 5-percent increase in consumption at electric utility plants. Total consumer stocks, at 153 million short tons, and electric utility stocks, at 144 million short tons, were at their lowest quarterly level since the end of 1989. US. coal exports totaled 19 million short tons, 6 million short tons less than in the first quarter of 1992, and the lowest quarterly level since 1988. The decline was primarily due to a 1-million-short-ton drop in exports to each of the following destinations: Italy, France, Belgium and Luxembourg, and Canada.

  17. Growth mechanisms, polytypism, and real structure of kaolinite microcrystals

    SciTech Connect (OSTI)

    Samotoin, N. D.


    The mechanisms of growth of kaolinite microcrystals (0.1-5.0 {mu}m in size) at deposits related to the cluvial weathering crust, as well as to the low-temperature and medium-temperature hydrothermal processes of transformations of minerals in different rocks in Russia, Kazakhstan, Ukraine, Czechia, Vietnam, India, Cuba, and Madagascar, are investigated using transmission electron microscopy and vacuum decoration with gold. It is established that kaolinite microcrystals grow according to two mechanisms: the mechanism of periodic formation of two-dimensional nuclei and the mechanism of spiral growth. The spiral growth of kaolinite microcrystals is dominant and occurs on steps of screw dislocations that differ in sign and magnitude of the Burgers vector along the c axis. The layered growth of kaolinite originates from a widespread source in the form of a step between polar (+ and -) dislocations, i.e., a growth analogue of the Frank-Read dislocation source. The density of growth screw dislocations varies over a wide range and can be as high as {approx}10{sup 9} cm{sup -2}. Layered stepped kaolinite growth pyramids for all mechanisms of growth on the (001) face of kaolinite exhibit the main features of the triclinic 1Tc and real structures of this mineral.

    Brown, S.


    This document describes the contents of a digital database containing maximum potential aboveground biomass, land use, and estimated biomass and carbon data for 1980. The biomass data and carbon estimates are associated with woody vegetation in Tropical Africa. These data were collected to reduce the uncertainty associated with estimating historical releases of carbon from land use change. Tropical Africa is defined here as encompassing 22.7 x 10{sup 6} km{sup 2} of the earth's land surface and is comprised of countries that are located in tropical Africa (Angola, Botswana, Burundi, Cameroon, Cape Verde, Central African Republic, Chad, Congo, Benin, Equatorial Guinea, Ethiopia, Djibouti, Gabon, Gambia, Ghana, Guinea, Ivory Coast, Kenya, Liberia, Madagascar, Malawi, Mali, Mauritania, Mozambique, Namibia, Niger, Nigeria, Guinea-Bissau, Zimbabwe (Rhodesia), Rwanda, Senegal, Sierra Leone, Somalia, Sudan, Tanzania, Togo, Uganda, Burkina Faso (Upper Volta), Zaire, and Zambia). The database was developed using the GRID module in the ARC/INFO{trademark} geographic information system. Source data were obtained from the Food and Agriculture Organization (FAO), the U.S. National Geophysical Data Center, and a limited number of biomass-carbon density case studies. These data were used to derive the maximum potential and actual (ca. 1980) aboveground biomass values at regional and country levels. The land-use data provided were derived from a vegetation map originally produced for the FAO by the International Institute of Vegetation Mapping, Toulouse, France.

  19. African oil plays

    Clifford, A.J. )


    The vast continent of Africa hosts over eight sedimentary basins, covering approximately half its total area. Of these basins, only 82% have entered a mature exploration phase, 9% have had little or no exploration at all. Since oil was first discovered in Africa during the mid-1950s, old play concepts continue to bear fruit, for example in Egypt and Nigeria, while new play concepts promise to become more important, such as in Algeria, Angola, Chad, Egypt, Gabon, and Sudan. The most exciting developments of recent years in African oil exploration are: (1) the Gamba/Dentale play, onshore Gabon; (2) the Pinda play, offshore Angola; (3) the Lucula/Toca play, offshore Cabinda; (4) the Metlaoui play, offshore Libya/Tunisia; (5) the mid-Cretaceous sand play, Chad/Sudan; and (6) the TAG-I/F6 play, onshore Algeria. Examples of these plays are illustrated along with some of the more traditional oil plays. Where are the future oil plays likely to develop No doubt, the Saharan basins of Algeria and Libya will feature strongly, also the presalt of Equatorial West Africa, the Central African Rift System and, more speculatively, offshore Ethiopia and Namibia, and onshore Madagascar, Mozambique, and Tanzania.

  20. A Tribute to Klaus Ruedenberg

    Xantheas, Sotiris S.; Gordon, Mark S.


    I am indebted to my father for living, but to my teacher for living well" said Alexander the Great, the King of Greek Macedonia, about his teacher, the philosopher Aristotle. This statement echoes the widely held belief of the students, research associates, collaborators and admirers of Klaus Ruedenberg regarding his invaluable contribution towards shaping their scientific lives. This special issue of the Journal of Physical Chemistry presents a tribute to Professor Klaus Ruedenberg, on the occasion of his 90th birthday, for his numerous scientific contributions to the field of quantum chemistry. The many outstanding papers that are part of this issue document his seminal contributions to a broad range of quantum chemistry, including the evaluation of electron repulsion integrals, the free-electron network model for conjugated molecules, the origin of covalent bonding, including the central role of the kinetic energy in the covalent bond, and the intrinsic identification of chemical bonding patterns in molecular systems, orbital localization that has enabled a deep understanding of many chemical phenomena, the multi-configurational self-consistent field method and the concept of the Full Optimized Reaction Space (FORS) to study chemical rearrangements and its application to the study of global potential energy surfaces and conical intersections, the first construction of systematic, eventempered sequences of orbital sets that approach the complete basis set limit, and the novel simultaneous extrapolation of basis set and level of theory to achieve nearly exact molecular energies and vibrational spectra. In addition, as past students and research associates of Klaus Ruedenberg, that is people whose scientific and personal lives have been critically affected by a great teacher, we wish to point out a less well-known aspect of his professional career, that of an educator. Professor Klaus Ruedenberg has a passion for communicating scientific ideas and educating
