Global Mercury Emissions to the Atmosphere from Natural and Anthropogenic Sources -- Mercury emissions from coal combustion in China -- Mercury emissions from industrial sources in China -- Mercury emissions from industrial sources in India and its effects in the environment -- Mercury emissions from point sources in South Africa -- World emissions of mercury from artisanal and small scale gold mining -- Mercury emissions from natural processes and their importance in the global mercury cycle -- Mercury emissions from global biomass burning: spatialand temporal distribution -- Spatial coverage and temporal trends of land-based atmospheric mercury measurements in the Northern and Southern Hemispheres -- Spatial coverage and temporal trends of atmospheric mercury measurements in Polar Regions -- Spatial coverage and temporal trends of over-water, air-surface exchange, surface and deep sea water mercury measurements -- Monitoring and modeling projects for fate of Hg species in Japan -- The need for a coordinated global Hg monitoring network for global and regional models validation -- Our current understanding of major chemical and physical processes affecting mercury dynamics in the atmosphere and at the air-water/terrestrial interfaces -- Mercury chemical transformations in the gas, aqueous and heterogeneous phases: state-of-the-art science and uncertainties -- Importance of a global scale approach to using regional models in the assessment of source-receptor relationships for mercury -- Global mercury modelling at Environment Canada -- The Geos-Chem model -- The ECHMERT model -- The EMEP/MSC-E mercury modeling system -- The AER/EPRI global chemical transport model for mercury (CTM-HG). Mercury Fate and Transport in the Global Atmosphere highlights major issues related to the interactions of mercury with terrestrial and aquatic ecosystems, and evaluates the relative contribution of anthropogenic and natural sources to the global atmospheric mercury budget. This book provides a state-of-the-art overview on different aspects related to mercury emissions from natural and anthropogenic sources, the evaluation of mercury concentrations and fluxes in different regions of the world, and global atmospheric mercury models currently used to assess spatial distributions of mercury compounds in ambient air and source-receptor relationships. The preparation of this book has been made possible thanks to the contributions of all members of the United Nations Environment Programme Global Partnership for Mercury Air Transport and Fate Research (UNEP-MFTP), and of more than 70 scientists from leading universities and research institutions recognized as worldwide experts on different aspects related to emissions, monitoring and modeling mercury in the atmosphere and other environmental compartments. Mercury Fate and Transport in the Global Atmosphere is intended to provide a scientific support to nations and the UNEP Governing Council that have been asked to shape the most efficient and economic concerted actions to reduce the impact of mercury contamination on human health and the environment.
