Organometallic Compounds in the Environment


Book Description

A knowledge of the chemical structure and concentration of organometal compounds throughout the ecosystem is important in working out the pathways and mechanisms by which metals distribute themselves throughout the environment. Treating the topic as an integrated subject area, the Second Edition of Organometallic Compounds in the Environment covers all the recent developments in analytical techniques and reports all the new work that has been achieved since the first book. Covers the general importance and characteristics of organometallic species. Includes general developments in analytical techniques. Discusses several minority elements including antimony and selenium. The book addresses the subject in a single, manageable size and each chapter can be used either as a single review or sequentially within the topic area. A useful resource for all researchers and scientists in industry working with organometallic compounds, including, chemists, environmentalists and ecologists.







Methods for the Analysis of Organometallic Compounds in Wastes


Book Description

Organometallic compounds occur in the environment as a result of anthropogenic and biogenic processes. Since organometals are often much more toxic than the corresponding inorganic forms of metals, it is important to be able to speciate the forms of metals in environmental samples at ultratrace levels. Chemical speciation methods, based on the use of chromatographic separations followed by element-selective detection, have been developed in our laboratories and elsewhere. These methods, described in part in this paper, are helping us to measure organometal species at their action levels (down to parts-per-trillion levels) in environmental matrices, leading to a better understanding of environmental occurrence, fate, effects, and transformation. New methods for nondestructive analysis of metal species on surfaces are under development.




Organometallic Compunds in the Environment


Book Description

The only current single-volume source of information on the topic. Looks at environmental and toxicity problems caused by the occurrence of organomercury compounds in the environment, including the involvement of gasoline additives, methyl and ethyl, polymers, organosilicas, and additives and catalysts. Provides a comprehensive guide to the chemical, environmental, industrial, and biogeochemical properties of the subject.




Organometallics in Environment and Toxicology


Book Description

Volume 7, devoted to the vital and rapidly expanding research area around metal-carbon bonds (see also MILS-6), focuses on the environment. With more than 2500 references, 35 tables, and nearly 50 illustrations, many of these in color, it is an essential resource for scientists working in the wide range from organometallic chemistry, inorganic biochemistry, environmental toxicology all the way through to physiology and medicine. In 14 stimulating chapters, written by 29 internationally recognized experts, Organometallics in Environment and Toxicology highlights in an authoritative and timely manner environmental cycles of elements involving organometal(loid) compounds as well as the analytical determination of such species. This book examines methane formation involving the nickel coenzyme F430, as well as the organometal(loid) compounds formed by tin, lead, arsenic, antimony, bismuth, selenium, tellurium, and mercury. In addition, it deals with the environmental bioindication, biomonitoring, and bioremediation of organometal(loid)s, and it terminates with methylated metal(loid) species occurring in humans by evaluating assumed and proven health effects caused by these compounds.




Recent Progress in Organometallic Chemistry


Book Description

The book Recent Progress in Organometallic Chemistry mostly reviews the modem techniques and substantial organometallic and medical applications of inorganic materials. Chapters of this book are invited and contributed from the experts throughout the world from prominent researchers and scientists in the field of inorganic chemistry on organometallics and metallocenes. Each chapter provides technical and methodological details beyond the level found in typical journal articles or reviews and explores the application of organometallics, medicinal, inorganic, and catalysis to a significant problem in medical and catalysis, also providing a prospectus for the future. This book compiles with the expert knowledge of many specialists in the organic-inorganic synthesis and use of inorganic catalyst and metallocenes including chemical catalysis, biological catalysis, photo-electrocatalysis, bioassays, industrial catalysis, large-scale synthesis, micro-nanocatalyst, and so on in the field of fundamental and applied organometallic chemistry. Highlighting and importance are included on real and practical problems, ranging from industrial to medical applications and from single-multicells to animal to human objects. This offers the unique opportunity of exchanging and combining the scientist or researcher in organometallic chemistry in largely chemistry, biological, biomedical, physiological, metallocene, and inorganic chemistry fields.




Occurrence, Toxicity & Analysis of Toxic Compounds in Oceanic Biota


Book Description

The presence of concentrations of organic substances and cations in sea water is a matter of increasing concern to the water industry, environmentalists and the general public alike. There is a threat of possible health hazards to both human, fish and crustacea. Occurrence, Toxicity and Analysis of Marine Biota discusses bioaccumulation in biota as well as occurrence and analysis of toxicants in biota. The main thrust of this book will be a review of the levels of toxicants found in the tissues of fish and invertebrates at various sites throughout the world. In addition, results will be reported on the levels of toxicants found in marine biota enabling ill health or death to occur. This will involve a discussion of toxicity index LC50 and percentile S95 concentration of toxicants and their implications on animal health and mortality, also that of humans who eat these sea creatures. The book will be a complete logical survey of this topic.







Chemistry of Marine Water and Sediments


Book Description

The most important processes on the Earth`s surface occur in the Ocean where materials and energy are primarily exchanged. In the case of marine chemistry different fields of chemistry from organic to inorganic as well as thermodynamics and biochemistry are involved. Analytical Chemistry is a very important tool for the quantification of biogeochemical processes by providing correct and even more sophisticated methodologies. These are often directly applied 'in situ', in order to detect trace and ultra-trace natural and anthropogenic substances. Kinetic and thermodynamic studies allow us to establish whether the process occurs. Once discovered it is then possible to build up general models for environmental systems. This book gathers many aspects with the aim of creating a general picture of the chemical processes occurring in the marine environment
