    From 1999 to 2003 a multipurpose regional geochemical mapping project, was carried out in Finland, and the NW-part of Russia. An important aim of the project is to define the anthropogenic impact in relation to the natural variations in regional geochemical baselines of heavy metals and other elements over a large area containing several of the largest industrial emitters in Europe but also some of its most pristine areas. Terrestrial moss, the organic layer, stream waters, and the C-horizon soil samples were collected from1085 sites in Russia and 288 sites in Finland, giving an average density of one site per 1000 km2. Both total and aqua regia extractable element concentrations were determined from <2 mm fraction of minerogenic samples, and total concentrations of organic soil samples and terrestrial moss were measured after strong acid leach, bioavailable concentrations of organic layer soil samples were measured, too. Concentrations of more than 50 elements, radionuclides, and other parameters were determined. Different extraction methods were used in order to study the speciation and bioavailability of the elements.Maps showing the distribution of 48 elements and other parameters are included in this atlas. The anomaly patterns of minerogenic C-horizon data are strongly controlled by element distributions in the bedrock. Stream water data are mainly controlled by geological formations and structures both for major and trace elements, but in some cases the influence of anthropogenic activities could be detected as elevated heavy metal concentrations. Anomaly patterns from moss data reflect mainly anthropogenic activities, but in areas such as mountains and tundra the geogenic dust also has a strong influence. It was not possible to detect any long distance airborne transport of heavy metals from industrialized areas to clean arctic regions.

  • Corrosion Induced by Low-Energy Radionuclides

    Modeling of Tritium and Its Radiolytic and Decay Products Formed in Nuclear Installations
    • 1st Edition

    • English
    Nuclear power plants emit radiation and particles across a range of energies. This radiation can cause corrosion to occur in critically important parts of the plant, which can lead to efficiency and safety problems. Gamma rays and neutrons have the highest energies and can break the metal bonds in interior metallic structures causing damage quickly and in easily monitored ways. Consequently these types of radiation and the best alloys to use to mitigate their effects have been extensively researched and their findings applied. However, the same is not true of low energy radiation which effects metal structures in a different way but can still cause appreciable and expensive corrosion. Low energy radiation degrades the passive oxide layers that protect metals. Without this protective layer the metals are easily corroded. This book uses tritium and tritiated water as models to describe the effects of low energy radiation on the corrosion of metals in these environments. Comprehensive coverage of the fields of liquid and gas flow, heat exchange, gas diffusion in materials, and of materials resistance to corrosion is ensures the reader has a full understanding of how these processes effect corrosion in nuclear installations. Such an understanding is essential for the efficient and safe running of all modern plant that uses radioactive material and this book is a critical reference tool for anyone involved in the nuclear power industry or metals research.* Unique coverage of low energy radiation and its corrosive effects in nuclear installations * Provides coverage of basic scientific principles contributing to corrosion * An essential reference for the safe and efficient construction and operation of nuclear installations * Applications in power generation, fuel reprocessing, military and civilian applications.

    Dopamine is a major neurotransmitter of the brain involved in the control of movement, emotion, and cognition; disturbance in dopamine function is associated with disorders like Parkinson’s disease, schizophrenia and attention deficit hyperactivity disorder. This volume of the Handbook of Chemical Neuroanatomy provides a series of in depth critical reviews of our present understanding of the most important aspects of dopamine’s organisation and disturbed function in the animal and human brain.

    Nanofiltration processes are finding wide applications in several 'wet' industries, such as water/wastewater treatment, water re-use, textile industry, diary industry, food industry and the pulp and paper industries. Despite this, no definitive book exists which covers the principles of the techniques and their potential and actual applications. ' Nanofiltration: Principles and Applications ' is edited by three well-known specialists from Australia, and contains chapters from top international authorities. The result is a comprehensive and up to date account which will be essential reading for membrane designers, manufacturers and end-users worldwide.
