Mercury in Water and Soil
Mercury can enter lakes Mercury can enter water by many different routes and processes:
  • wet and dry atmospheric depositions
  • particle flux to sediments
  • dissolved species exchange at sediment/water interfaces
  • gas exchange at air/water/surface interfaces
  • moving dissolved species exchange and particle flux via stream and rivers
  • dissolved species exchange via runoff from groundwater to lakes
  • direct discharge of dissolved species via groundwater to lakes
  • gas exchange at soil-air ion interfaces

Manmade discharges may result from industrial processes, such as:
  • chlorine-alkali production
  • mining operations
  • paper mills
  • leather tanning
  • pharmaceutical production
  • textile manufacture
