Sources of mercury deposited to aggregated world regions for the present-day and for the four 2050 IPCC scenarios of Streets et al. (10). Numbers give annual net deposition fluxes to the receptor region (gross deposition fluxes in parentheses), and for 2050 represent the range of the IPCC scenarios. Pie charts show relative source contributions to deposition (average of the scenarios for 2050). “New anthropogenic” refers to mercury from primary emissions (coal combustion, waste incineration, mining) including recycling through surface reservoirs (ocean mixed layer, vegetation). “Legacy” refers to anthropogenic mercury recycled from intermediate reservoirs with a time scale of decades or longer and included in GEOS-Chem as boundary condition.
