Summary: The book that looks at mercury's impact on the planet today Recent research by the EPA has concluded that one in six women of childbearing age have unsafe levels of mercury in their bodies, which puts 630,000 newborn babies each year at risk of neurological impairment. Mercury poses severe risks to the health of animals and ecosystems around the world, and this book provides the essential information that anyone interested in environmental sciences should know about the fundamentals of the entire mercury cycle. Comprised of four parts that present an overview of mercury in the environment, mercury transformations, transport, and bioaccumulation and toxicology, each chapter of Environmental Chemistry and Toxicology of Mercury includes the basic concepts of the targeted subject, a critical review of that subject, and the future research needs. This book explains the environmental behavior and toxicological effects of mercury on humans and other organisms, and provides a baseline for what is known and what uncertainties remain in respect to mercury cycling. The chapters focus on the fundamental science underlying the environmental chemistry and fate of mercury. This work will be invaluable to a wide range of policy experts, environmental scientists, and other people requiring a comprehensive source for the state of the science in this field.Summary: Intro -- ENVIRONMENTAL CHEMISTRY AND TOXICOLOGY OF MERCURY -- CONTENTS -- PREFACE -- ACKNOWLEDGMENTS -- CONTRIBUTORS -- 1 OVERVIEW OF MERCURY IN THE ENVIRONMENT -- 1.1 Introduction -- 1.2 Toxicity and Health Risks of Mercury Exposure -- 1.3 Sources of Mercury -- 1.4 Overview of Mercury Biogeochemical Cycling -- 1.5 Structure of the Book -- 1.6 Concluding Remarks -- References -- PART I ANALYTICAL DEVELOPMENTS -- 2 ADVANCES IN SPECIATION ANALYSIS OF MERCURY IN THE ENVIRONMENT -- 2.1 Introduction -- 2.2 Sample Preparation for Hg Speciation in Environmental Samples -- 2.3 Application of GC Technique in Hg Speciation Analysis -- 2.4 Application of HPLC Technique in Hg Speciation Analysis -- 2.5 Application of Capillary Electrophoresis Techniques in Hg Speciation Analysis -- 2.6 Application of X-Ray Absorption Spectroscopy in Probing Chemical Microenvironment of Hg -- 2.7 Application of Stable Isotope Dilution Technique in Mercury Speciation Analysis -- 2.8 Summary -- References -- 3 MEASURING GAS PHASE MERCURY EMISSIONS FROM INDUSTRIAL EFFLUENTS -- 3.1 Introduction -- 3.2 Standardized Methods for Measuring Mercury -- 3.3 Mercury Continuous Emission Monitors (CEMs) -- 3.4 Future Outlook -- References -- PART II SPECIATION AND TRANSFORMATION -- 4 ATMOSPHERIC CHEMISTRY OF MERCURY -- 4.1 Introduction -- 4.2 The Overall Picture -- 4.3 Chemical Transformations in the Gas Phase -- 4.4 Chemical Transformations in the Aqueous Phase -- 4.5 Redox Chemistry at the Interface Between the Atmosphere and Earth's Surfaces -- 4.6 Atmospheric Implications of the Identified Redox Pathways -- 4.7 Future Research Needs -- References -- 5 MICROBIAL TRANSFORMATIONS IN THE MERCURY CYCLE -- 5.1 Introduction -- 5.2 Mercury Methylation -- 5.3 Methylmercury Degradation -- 5.4 Redox Cycling of Inorganic Hg -- 5.5 Conclusions -- References.PPN: PPN: 809503697Package identifier: Produktsigel: ZDB-26-MYL | ZDB-30-PAD | ZDB-30-PQE
