Fate of mercury in the Arctic (FOMA)

This report is the final reporting of the project FONA, funded by the Danish Environmental Protection Agency with means from the MIKA/DANCEA funds for Environmental Support to the Arctic Region. The aim of the project is to study the intercompartment mercury transport chain in the arctic area. From atmospheric deposition of mercury on sea surfaces to uptake in marine organisms, bio-accumulation...

Sources of Mercury in the Arctic

Global and regional emission inventories of mercury are reviewed with special emphasis on the source regions with potential impact on the Arctic environment. These sources are located mostly in Eurasia and North America and emit almost 1300 t of rig to the air annually. Combustion of fossil fuels to produce electricity and heat is the major source of rig. Major portion of the element emissions ...

Influence of snow and ice crystal formation and accumulation on mercury deposition to the Arctic.

Mercury is deposited to the Polar Regions during springtime atmospheric mercury depletion events (AMDEs) but the relationship between snow and ice crystal formation and mercury deposition is not well understood. The objective of this investigation was to determine if mercury concentrations were related to the type and formation of snow and ice crystals. On the basis of almost three hundred anal...
