Up-to-date coverage of vanadium research--in two accessible,self-contained volumes Vanadium in the Environment brings togetherthe contributions of leading experts on the chemical andtoxicological aspects of vanadium exposure and its effects onaquatic and terrestrial environments, human health, and wildlife.This initial volume focuses on chemistry and biochemistry, whilePart Two concentrates on health effects and toxicology in livingorganisms. Topics in this first volume include:* History, occurrence, and uses of vanadium* Vanadium in the atmosphere* Chemistry of relevance to vanadium in the environment* Water quality criteria for vanadium* Spectroscopic methods for the characterization of vanadiumcomplexes* Bioaccumulation and transfer of vanadium in marineorganisms* Structure, function, and models of biogenic vanadiumcompounds* Catalytic effects of vanadium on phosphoryl transferenzymes* Bioactivity of vanadium compounds on cells in culture

Focuses not only on various methods of sampling and analyzing gaseous pollutants in the atmosphere but also emphasizes an understanding of the chemical and physical processes that occur. Evaluates current measurement methods; reports on the results of recent research; and surveys the challenges that lie ahead. Of particular interest is an expert overview of the sources, occurrences and characteristics of volatile organic compounds in indoor environments--a growing public health concern.

The chemical enigma that is both a pollutant and anantipollutant--and environmental science's newest causecelebre.oxidants Responsible for chemical reactions both harmfuland benign, oxidants represent the sort of chemical puzzle thathave scientists both concerned and fascinated. Implicated in deadlysmog episodes and arteriosclerosis, oxidants have also played amajor role in treating polluted waters and in certain anticancerdrugs. A broad-based, up-to-date examination of the environmentalchemistry and toxicology of oxidants, Environmental Oxidants is acompendium of the latest research being done in the field. Bringingtogether the work of noted researches, the book contains a detailedlook at:* Evolution, production, distribution, and fate of oxidants in theatmosphere, hydrosphere, and biosphere* Influence of human activities on oxidative processes in theatmosphere* Oxidative stress at the cellular, systemic, and ecosystemlevels* Use of oxidants in wastewater treatment processesA selective and incisive look at the current state of research onoxidants, Environmental Oxidants provides environmental scientistsand engineers with an informative, detailed discussion of just howand why oxidants have emerged as a key issue in human health andenvironmental integrity.
