WHAT ARE THE KEY ISSUES FOR THE EVERGLADES?
DOC-Mercury Interactions The role of mercury complexation by DOC has been proposed by several investigators as a primary mechanism for the transport of mercury in aquatic systems. However, this relationship has been simply proposed based on a strong correlation between dissolved mercury and DOC concentrations in ground, lake and stream waters. The vast majority of mercury in aquatic systems resides in organic-rich soils and sediments. Interactions with DOC, however, may be an important process for the release of mercury into porewaters with subsequent transport into surface waters. Effective management strategies for dealing with this problem will require a more thorough understanding of the factors and processes that result in the generation and transport of Hg, and control its reactivity in the Everglades. Our studies will focus on the effect of dissolved organic carbon (DOC) on the transport and reactivity of Hg in the Everglades. Effects of land use practices Land and water use pra
