Global present-day budget of mercury as represented in GEOS-Chem. Blue arrows show primary and legacy sources of mercury to the atmosphere from long-lived deep reservoirs. Red arrows show the fates of mercury in surface (ocean, land, snow) reservoirs: recycling to the atmosphere or incorporation into more stable reservoirs (deep ocean, soils). Black arrows show deposition and redox fluxes. Green arrows show processes not explicitly modeled in GEOS-Chem. Order-of-magnitude residence times in individual reservoirs are also shown.
