Over a period of a year, Hg 0-reactive, total reduced sulfur species (RSS T), as well as a non-volatile fraction that cannot be gas-stripped at pH ∼2 (RSS NV), have been measured by voltammetry in a stratified, saline lake. In the hypolimnion, RSS T is dominated by unusually high (up to 5 mM) dissol...
