This book examines the environmental sources, geochemistry and human effects of trace elements. Topics discussed include an assessment of cancer and non-cancer health risk caused by trace element content in Belgrade; flow opto-sensing applied to the analysis of trace elements; trace metals in fruits and vegetables and their effect on human health; excessive livestock mineral supplementation on environmental pollution; assessing the geochemistry of trace elements in canal sediments; and trace element deficiencies in crops.

Free Download Medical Geochemistry: Geological Materials and Health By Paolo Censi, E. Tamburo, L. A. Randazzo, Pierpaolo Zuddas (auth.), Paolo Censi, Thomas Darrah, Yigal Erel (eds.)
2013 | 194 Pages | ISBN: 9400743718 | PDF | 5 MB
This book includes a collection of chapters illustrating the application of geochemical methods to investigate the interactions between geological materials and fluids with humans. Examples include the incorporation and human health effects of inhaling lithogenic materials, the reactivity of biological fluids with geological materials, and the impact on nascent biomineral formation. Biomineralization is investigated in terms of mineralogy, morphology, bone chemistry, and pathological significance with a focus on the health impacts of "foreign" geological/environmental trace element incorporation. One of the contribution is devoted to particulate matter, the presence of metals and metalloids in the environment, and the possibility of using human hair as a biomarker between environmental/geological exposure and human bioincorporation. Other chapters focus on the last advances on the analytical methods and instrumentational approaches to investigating the chemistry of biological fluids and tissues.

Free Download Handbook of Environmental Isotope Geochemistry: Vol I By Mark Baskaran (auth.), Mark Baskaran (eds.)
2012 | 951 Pages | ISBN: 3642106366 | PDF | 19 MB
Applications of radioactive and stable isotopes have revolutionized our understanding of the Earth and near-earth surface processes. The utility of the isotopes are ever-increasing and our sole focus is to bring out the applications of these isotopes as tracers and chronometers to a wider audience so that they can be used as powerful tools to solve environmental problems. New developments in this field remain mostly in peer-reviewed journal articles and hence our goal is to synthesize these findings for easy reference for students, faculty, regulators in governmental and non-governmental agencies, and environmental companies. While this volume maintains its rigor in terms of its depth of knowledge and quantitative information, it contains the breadth needed for wide variety problems and applications in the environmental sciences. This volume presents all of the newer and older applications of isotopes pertaining to the environmental problems in one place that is readily accessible to readers. This book not only has the depth and rigor that is needed for academia, but it has the breadth and case studies to illustrate the utility of the isotopes in a wide variety of environments (atmosphere, oceans, lakes, rivers and streams, terrestrial environments, and sub-surface environments) and serves a large audience, from students and researchers, regulators in federal, state and local governments, and environmental companies.

Free Download Groundwater Geochemistry: A Practical Guide to Modeling of Natural and Contaminated Aquatic Systems By Broder J. Merkel, Britta Planer-Friedrich (auth.), Darrell K. Nordstrom (eds.)
2008 | 230 Pages | ISBN: 3540746676 | PDF | 5 MB
To understand hydrochemistry and to analyze natural as well as man-made impacts on aquatic systems, hydrogeochemical models have been used since the 1960’s and more frequently in recent times. Numerical groundwater flow, transport, and geochemical models are important tools besides classical deterministic and analytical approaches. Solving complex linear or non-linear systems of equations, commonly with hundreds of unknown parameters, is a routine task for a PC. Modeling hydrogeochemical processes requires a detailed and accurate water analysis, as well as thermodynamic and kinetic data as input. Thermodynamic data, such as complex formation constants and solubility-products, are often provided as databases within the respective programs. However, the description of surface-controlled reactions (sorption, cation exchange, surface complexation) and kinetically controlled reactions requires additional input data. Unlike groundwater flow and transport models, thermodynamic models, in principal, do not need any calibration. However, considering surface-controlled or kinetically controlled reaction models might be subject to calibration. Typical problems for the application of geochemical models are: * speciation * determination of saturation indices * adjustment of equilibria/disequilibria for minerals or gases * mixing of different waters * modeling the effects of temperature * stoichiometric reactions (e.g. titration) * reactions with solids, fluids, and gaseous phases (in open and closed systems) * sorption (cation exchange, surface complexation) * inverse modeling * kinetically controlled reactions * reactive transport Hydrogeochemical models depend on the quality of the chemical analysis, the boundary conditions presumed by the program, theoretical concepts (e.g.

Free Download Isotopes in Organic Geochemistry by Jan Schwarzbauer , Branimir Jovančićević
English | PDF EPUB (True) | 2024 | 72 Pages | ISBN : 3031693035 | 19.8 MB
This volume of the series Fundamentals of Organic Geochemistry provides an overview of isotope analysis in organic geochemistry and related fields of applied sciences. It dives deep into the basics of isotopes and isotopic fractioning processes with applications e.g. in environmental biodegradation or correlations of fossil matter. This textbook helps students understanding the geoscientific, analytical, and chemical isotope aspects in complex natural systems. Students learn the importance of isotope organic geochemistry and its relationship to fundamental processes in the geosphere and biosphere, which include e.g. photosynthesis, evaporation/precipitation within the global water cycle, biotic degradation, and biosynthesis.

Free Download Groundwater Quality and Geochemistry in Arid and Semi-Arid Regions by Shakir Ali, Abdelazim Negm
English | EPUB (True) | 2024 | 372 Pages | ISBN : 3031537769 | 124.8 MB
This book reviews groundwater quality and its major global contaminants, and collects the latest advances in the analysis, remediation, risk assessment, and hydrogeochemistry of groundwater in countries such as Algeria, Egypt, Ghana, Kazakhstan, Morocco, Saudi Arabia, and the USA. This book mainly focuses on the major arid and semi-arid areas where groundwater is scarce and highly polluted with geogenic and anthropogenic contaminants and the recharge to the groundwater is negligible due to limited rainfall.

English | 2024 | ISBN: 3031437438 | 201 Pages | PDF EPUB (True) | 146 MB
This book is based on the papers accepted for presentation during the 3rd Springer Conference of the Arabian Journal of Geosciences (CAJG-3). The book is of interest to all researchers in the fields of geomorphology, sedimentology, and geochemistry. Papers in the field of geomorphology deal with topics related to fault slip and incision rates, soil science, landslides and debris flows, coastal processes, and geoarcheology and geoheritage. Papers in the field of sedimentology cover research studies in stratigraphy and environmental, tectonic, and diagenetic processes, together with studies focusing on the evolutionary, biostratigraphic, and paleo-environmental significance of paleontology. This section also contains papers on marine geosciences, from molecular proxies related to climate to geophysical surveys. The third set of papers focuses on studies related to geochemistry that are focused on sedimentary geochemistry and mineralogical characterization, magmatic and metamorphic processes and products, and the origin and exploration of mineral deposits. This book resumes the current situation related to the abovementioned topics mainly in the Mediterranean realm and its surroundings. The book is of interest to all researchers, practitioners, and students in the fields of geomorphology, sedimentology, and geochemistry.
