Mercury Transportation in Soil Using Gypsum from Flue Gas Desulphurization Unit in Coal-Fired Power Plant
<p>This work investigates mercury flux in soil amended by gypsum from flue gas desulphurization (FGD) units of coal-fired power plants. There are two phases of this research, including field and greenhouse studies. Previous studies indicate that FGD gypsum could increase corn yield, but may lead to …

Regulating mercury with the Clear Skies Act : the resulting impacts on innovation, human health, and the global community
… Act Amendments require the U.S. EPA to control mercury emission outputs from coal-burning power plants through implementation of MACT, Maximum Achievable Control Technology, standards. However, in 2003 the Bush Administration revealed an alternative and controversial regulatory strategy for …

Gas Exchange Of Hg Over Wetlands, Effect Of Biochar And Activated Carbon On Hg Emissions From Soil, And Seasonal Concentrations Of Hg In Rain
Mercury (Hg) is a global pollutant with human-health and ecological impacts. Gaseous Hg exchange between the atmosphere and aquatic or terrestrial surfaces serves as an important, but not well understood, route for Hg to enter and exit ecosystems. To better understand the role of gaseous Hg …

Investigation of the Relationship Between Particulate Bound Mercury and Properties of Fly Ash in a Full-Scale 100 MWE Pulverized Coal Combustion Boiler
There is an increasing concern over mercury emissions from coal-fired boilers. Coal-fired power generation accounts for approximately 33% of total mercury emission in the United States. Once it is emitted into the atmosphere and deposited on land or water, mercury can transform into methylmercury, …

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 …

Quantifying mercury surface fluxes by combining atmospheric observations and models
Mercury (Hg) is a critical environmental concern. Although an important component of its biogeochemical cycle, large uncertainties still exist in the estimates of surface fluxes of mercury. Three projects presented in this thesis improve our understanding of mercury surface fluxes at different …

Evaluation Of A Low Corrosion Method To Increase Mercury Oxidation And Scrubber Capture
… one of the major contributors of the atmospheric mercury in the Lake Superior basin by the Lake Superior Lakewide Management Plan (LaMP). Mercury is a leading concern among air toxic metals due to its volatility, persistence and bioaccumulation as methylmercury in the environment, and its …

Oxy-Coal Combustion: Submicrometer Particle Formation, Mercury Speciation, And Their Capture
… including the control of particulate matter, mercury, and trace metals, and carbon oxide: CO2) emissions. The rising of CO2 level in the atmosphere due to burning of fossil fuels is one of the major factors contributing to the global climate change. Capturing CO2 from coal combustion exhaust …

NEW APPROACHES FOR MITIGATING ENVIRONMENTAL CONCERNS ASSOCIATED WITH COAL AND COAL COMBUSTION PRODUCTS
… a need to design new strategies to clean coal. Mercury can be found in fly ash, bottom ash, and flue gas desulfurization (FGD) material. The Hg is transferred to these coal combustion products (CCPs) from its associated parent coal. These CCPs absorb a significant amount of the Hg released …
