Abstract(unpublished)
This section of the Introductory chapter of the 2018 UNEP Global Mercury Update Assessment covers recent improvements (since 2012) in our understanding of the cycling and mass balance budget of mercury in the global environment. Key topics include: new information on historical and current inputs from natural geogenic, and anthropogenic, sources; rates of removal of mercury from the bioactive environment, especially the oceans; the importance in the present environment of historical mercury emissions from small-scale and artisanal gold, silver and mercury mining in past centuries; and uncertainties in our present understanding of the global mercury model.
Summary(Plain Language Summary, not published)
The goal of the 2018 Global Mercury Update Assessment is to report to UNEP Governing Council on the state of science at present concerning mercury in the global environment, including sources, environmental geochemistry, transport, and human and wildlife health. This Introductory section of the Assessment covers recent improvements (since 2012) in our understanding of the cycling and mass balance budget of mercury in the global environment. Key topics include: new information on historical and current inputs from natural geogenic, and anthropogenic, sources; rates of removal of mercury from the bioactive environment, especially the oceans; the importance in the present environment of historical mercury emissions from small-scale and artisanal gold, silver and mercury mining in past centuries; and uncertainties in our present understanding of the global mercury model.
