In order to construct local, regional, and global Hg budgets, the amount of Hg released by terrestrial surfaces to the atmosphere must be understood. Chapter 1 focused on measuring mercury emissions and reactive gaseous mercury concentrations at the Sulphur Bank Mercury Mine. It was estimated that this area emits 5.29 to 9.0 kg Hg yr<super>−1</super>, and reactive gaseous mercury concentrations measured are the highest ever reported for a natural setting (0.04 to 75.88 ng m<super>−3</super>). The goal of chapter 2 was to quantify mercury emissions from background and altered substrate from Nevada. Mercury fluxes from background substrate were 2.0 ± 4.1 ng m<super>−2</super> hr<super>−1</super> and for altered substrate were 15.5 ± 24.2 ng m<super>−2</super> hr<super>−1</super>. Chapter 3 focused measuring Hg flux from mine waste at the Aurora and Alpine Mines pre and post remediation. Mercury emissions were significantly lower one year after the waste was moved and capped than before remediation.
