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.
