Abstract

Reservoirs play a complicated role in the transportation of mercury (Hg) the river reservoir ecosystems. Under different environmental conditions, reservoirs can be a sink for Hg to the outflow river, a source of Hg to the inflow river, or a place for Hg to transform from inorganic Hg (IHg) to methylmercury (MeHg). The different pathways for regulation and operation in the reservoir lead to distinct water exchange frequencies and residence times as well as distinct source-sink characteristics for the reservoir. In this chapter, we (1) estimated the input/output fluxes of Hg species (THg and MeHg) in a reservoir and (2) assessed the role of different reservoir stages on the source/sink of Hg in the transportation and transformation of Hg in a river reservoir ecosystem.
