- •
Occurrence of even mercury isotope anomalies is imprinted onto surface water.
- •
Mercury isotope anomalies establish a direct link of Hg in lake surface waters to atmospheric deposition.
- •
Watershed methylmercury is also an important Hg source in lake waters and food webs.
- •
Lake sediments are isotopically decoupled from the lake waters and the atmosphere.
