Assessment of the Suitability of Tree Rings as Archives of Atmospheric Mercury Pollution using Tree Cores and Results of a controlled field experiment to assess the use of tree tissue concentrations as bioindicators of air Hg
Peckham, Matthew (2018)Mercury (Hg), a toxic metal and known neurotoxin, is a widespread environmental contaminant. The element, and its speciated compounds, are released naturally through geothermal and volcanic activity, but global concentrations ... -

Characterization of mercury concentration, form, and air-surface exchange associated with the area surrounding and within two Nevada gold mines
Miller, Matthieu B. (2010)This project focused on developing a dataset that would allow for prediction of mercury (Hg) release to the air from an area prior to mining, and the potential for mining releases to impact Hg concentrations and cycling ... -

Ozone in Rural Nevada: Investigating spatio-temporal patterns and source regions contributing to elevated concentrations
Fine, Rebekka (2014)In 1993, an ozone (O3) monitoring site was established at Great Basin National Park (GBNP), located in rural eastern Nevada. Analyses of data from this site indicate that compliance with a revised National Ambient Air ... -
