Figure 2. ORNL field flux chamber system for measurement of Hg emissions from natural surfaces in background regions where the primary Hg flux is thought to originate from previously deposited Hg being re-emitted. Samples are collected on gold-coated sand traps for later Hg analysis by cold vapor atomic fluorescence [e.g., Lindberg et. al. 2000 (Biogeochemistry, 48:237-259).] |
