Atmospheric Mercury Deposition In An Urban Environment
Atmospheric mercury deposition, known to be a major source of mercury to aquatic and terrestrial environments, was studied at an urban site in Orlando, FL. Precipitation sampling was conducted from September 2003 to May 2006 at a Mercury Deposition Network site located on the University of Central …

Elemental and reactive gaseous mercury deposition and diurnal cycles over terrestrial environments
… component of the global biogeochemical mercury cycle was studied to determine the mechanisms behind diurnal trends and amplitudes in elemental and reactive gaseous mercury concentrations over terrestrial environments. This analysis was done using the 3D GEOS-Chem chemical transport model …

Trace metal applications in atmospheric and watershed dynamics: Case studies of mercury deposition in New England and bedrock groundwater-surface water mixing
… the environmental chemistry of two trace metals, mercury (Hg) and strontium (Sr). Both are naturally occurring and exist in the environment at trace levels.</p><p>Chapters II-IV of this dissertation focus on understanding the atmospheric chemistry of Hg and the wet and dry deposition of this toxic …

The Association between Mercury Emissions and Individuals with Autism Aged from 3-21 in the State of California from 2001 to 2007
<p>The paper explores how historical mercury deposition associates with the incidents of autism, identified in individuals aged from 3 to 21 in California from 2001 to 2007. The association between mercury deposits and the prevalence of individuals with autism aged from 3 to 21 in California was …

Remediation Strategies for Mercury Contaminated Lakes and Reservoirs Within the State of California
<p>Mercury is an environmental and public health concern due to its neurodegenerative effects and ubiquitous concentration within the environment. To mitigate these risks and reduce concentrations within the environment, remediation methods are necessary. The purpose of this paper is to investigate …

Mercury Amalgam Electrodeposition on Metal Microelectrodes
Mercury amalgam microelectrodes, typically fabricated by electrodeposition of mercury onto metal (platinum, gold, silver) inlaid disks, possess certain advantageous properties for scanning electrochemical microscopy (SECM) and electroanalysis. But as applications require more and more precision, …

Spatial Patterns of Mercury in Atmospheric Deposition, Soils and Lake Biota in the Adirondack Park, New York
<p>Mercury (Hg), as a trace element cycling in the environment, poses a serious health threat to both humans and wildlife due to its toxicity. Atmospheric deposition is the main source of Hg to most remote environments. The Adirondack Park in New York State of the United States receives moderate Hg …

Deposition and Fate of Atmospheric Mercury in Forested Landscapes of the Adirondack Park, NY
<p>In this dissertation, I investigated the deposition and fate of atmospheric mercury (Hg) to forested landscapes of the Adirondack region in Upstate New York. Despite the fact that forests are the dominant land cover in North America, there has been relatively little research on the deposition, …

A Gis Investigation of Regional Geologic Controls on Mercury Deposits in the Southwest Region of Arkansas
The mercury district of southwest Arkansas, located within Clark, Pike, and Howard counties, contains 77 mapped mercury deposits, primarily in the form of cinnabar, found within the sandstones and shales of the Stanley and Jackfork Formations. The geographic locations of the majority of the …
