Dynamics of Mercury Pollution on Regional and Global Scales

This book brings together authors with expertise in a wide range of fields to provide an up to the minute overview of the most important problems relating to mercury in the environment. The book reflects growing concern over the likelihood of harmful effects to human health and sensitive ecosystems posed by mercury in the light of increasing fossil fuel combustion, mercury use in a range of manufactured goods, and the lack of emission control policies. Concern has been expressed at local, national, and international levels; in the last three years both the European Commission and UNEP have published reports on mercury in the environment. Growing concern has led to an increased effort to understand the fate of mercury in the environment, including primary production and trade in mercury, emissions from manufacturing and power generation, natural emissions and re-emission, atmospheric transport and transformation, deposition patterns, uptake by biota, and eventual health impacts on living organisms. The increasing specialisation, and amount of research in the numerous scientific fields associated with the study of the fate of mercury in the environment, make the publication of this book both necessary and timely. For experts, and non-experts, who require both the broader picture, as well as an awareness of the latest progress in the fields relevant to mercury research, this book provides the most comprehensive and up to date overview available. The book has five sections.

Mercury pollution in different regions of the world is a growing concern from an environmental and epidemiological point of view. The increasing trends of energy production from fossil fuel combustion, mercury usage in a large variety of goods and products, and the lack of emission control policy, especially in fast developing countries, represent a major environmental and political issue for national and international organisations and governments as well. In the last decade, there has been a significant effort to improve our knowledge on different aspects involved in the biogeochemical cycle of mercury in the environment and its impact on human health. Special attention has been devoted to fill the gaps in our knowledge on physical and chemical processes involved in the transfer of mercury compounds released to the atmosphere from natural and anthropogenic sources to terrestrial and aquatic receptors. Significant progress was made on assessing the spatial and temporal distributions of atmospheric mercury and its depositional fluxes.

Dynamics of Mercury Pollution on Regional and Global Scales: Atmospheric Processes and Human Exposures Around the World provides a detailed overview of our current understanding of different dynamic patterns involved in the redistribution of mercury in the global environment, and its impact on human health and ecosystems.
