Available in PDF, EPUB and Kindle. Book excerpt: Inactive or abandoned uranium mill tailings in the uranium producing provinces of Ontario and Saskatchewan, have been studied to obtain information on some of the parameters that will enable predictions to be made about possible pathways for long-lived radionuclides to enter the surrounding environment. Populations of the major indigenous plant species that colonize these waste sites were identified. Physical and chemical data describing the surface of the uranium tailings and the associated surface water and biological data on the indigenous vegetation growing on the tailings were collected and are summarized. A comparison of physical factors and chemical factors of the tailings surface from three sites (Bancroft, Elliot Lake, and Uranium City) with soils from nearby control areas is presented. Similar physical and chemical characteristics were determined for surface waters and the results from these analyses are compared with those derived from leachate solutions from the root-zone depths of tailings. Vegetation are analyzed for radionuclide concentrations, and above-ground biomass and associated litter accumulations were also analyzed. The tailings characteristics reported are from four abandoned, unreclaimed uranium tailings sites; six inactive, revegetated sites; and two abandoned sites. All of the investigated sites are one to two decades old.

Download or read book Long term Ecological Behaviour of Abandoned Uranium Mill Tailings 2 Growth Patterns of Indigenous Vegetation on Terrestrial and Semi aquatic Areas written by M. Kalin and published by The Service. This book was released on 1984 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Semi-aquatic and terrestrial areas on abandoned or inactive uranium mill tailings in Ontario were studied in order to identify the growth characteristics of the naturally invading species dominating these areas. Semi-aquatic areas of tailings sites have been invaded by cattails. These species formed wetland communities which varied in size, but all were essentially monocultures of Typha latifolia, T. angustifolia, or of the hybrids T. glauca. Sedges, Scripus cyperinus (wool-grass) and Phragmites australis (reedgrass), were found in transition zones between the cattail stand and the dry section of the tailings site. The expansion of the cattail stands appeared to be controlled by the hydrological conditions on the site, rather than the chemical characteristics of the tailings"--Abstract, page i.

Download or read book Forty Years of Uranium Resources Production and Demand in Perspective written by OECD Nuclear Energy Agency and published by OECD Publishing. This book was released on 2006 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: The "Red Book", jointly prepared by the OECD Nuclear Energy Agency and the International Atomic Energy Agency, is a recognised world reference source on the uranium industry. This publication collates and analyses key information drawn from the twenty editions of the Red Book published between 1965 and 2004, in order to set out a comprehensive review of developments in the world uranium industry from the birth of civilian nuclear energy through to the beginning of the 21st century. It summarises developments in the major uranium-producing countries and topics covered include: installed nuclear capacity, reactor-related uranium requirements, market price, exploration, resources, production, natural and enriched uranium inventories, thorium, mine start-up and closure histories, environmental aspects of uranium mining and processing.

Download or read book A Preliminary Inventory and Assessment of Uranium Resources in Mine Wastes written by International Atomic Energy Agency and published by . This book was released on 2021-06-30 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Typically, discussions of the uranium production cycle are focused on either the economic extraction of resources, or on the environmental and remediation aspects as parallel aspects in a linear cradle-to-grave process. In this publication, resource evaluation is expanded to the full life of the mine to include evaluation of resources in residual waste products. This is viewed in the context of potential reuse or remining of so-called anthropogenic resources in a circular economy. The publication is intended to not only provide a preliminary inventory of uranium contained in mine wastes including the desirable goal of comprehensive extraction in the (uranium) mining industry, but also to provide an initial framework to integrate this aim with those of environmental and remediation considerations in achieving zero waste.

Download or read book Cellular Effects of Heavy Metals written by Gaspar Banfalvi and published by Springer Science & Business Media. This book was released on 2011-03-02 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term “heavy metals” is used as a group name of toxic metals and metalloids (semimetals) causing contaminations and ecotoxicity. In strict chemical sense the density of heavy metals is higher than 5 g/cm3. From biological point of view as microelements they can be divided into two major groups. a. For their physiological function organisms and cells require essential microelements such as iron, chromium (III), cobalt, copper, manganese, molidenium, zinc. b. The other group of heavy metals is toxic to the health or environment. Of highest concern are the emissions of As, Cd, Co, Cu, Hg, Mn, Ni, Pb, Sn, Tl. The toxicity of heavy metals is well known at organizational level, while less attention has been paid to their cellular effects. This book describes the toxicity of heavy metals on microorganisms, yeast, plant and animal cells. Other chapters of the book deal with their genotoxic, mutagenic and carcinogenic effects. The toxicity of several metals touch upon the aspects of environmental hazard, ecosystems and human health. Among the cellular responses of heavy metals irregularities in cellular mechanisms such as gene expression, protein folding, stress signaling pathways are among the most important ones. The final chapters deal with biosensors and removal of heavy metals. As everybody is eating, drinking and exposed to heavy metals on a daily basis, the spirit of the book will attract a wide audience.
