Title: Subtask 4.8 - Fate and Control of Mercury and Trace Elements

Abstract

The Center for Air Toxic Metals® (CATM®) Program at the Energy & Environmental Research Center (EERC) continues to focus on vital basic and applied research related to the fate, behavior, measurement, and control of trace metals, especially mercury, and the impact that these trace metals have on human health and the environment. For years, the CATM Program has maintained an international perspective, performing research and providing results that apply to both domestic and international audiences, with reports distributed in the United States and abroad. In addition to trace metals, CATM’s research focuses on other related emissions and issues that impact trace metal releases to the environment, such as SOx, NOx, CO2, ash, and wastewater streams. Of paramount interest and focus has been performing research that continues to enable the power and industrial sectors to operate in an environmentally responsible manner to meet regulatory standards. The research funded by the U.S. Department of Energy’s (DOE’s) National Energy Technology Laboratory (NETL) through CATM has allowed significant strides to be made to gain a better understanding of trace metals and other emissions, improve sampling and measurement techniques, fill data gaps, address emerging technical issues, and develop/test control technologies that allow industry to cost-effectivelymore » meet regulatory standards. The DOE NETL–CATM research specifically focused on the fate and control of mercury and trace elements in power systems that use CO2 control technologies, such as oxycombustion and gasification systems, which are expected to be among those technologies that will be used to address climate change issues. In addition, research addressed data gaps for systems that use conventional and multipollutant control technologies, such as electrostatic precipitators, selective catalytic reduction units, flue gas desulfurization systems, and flue gas-conditioning methods, to understand mercury interactions, develop better control strategies and, in some cases, prevent mercury from being reemitted. This research also addressed stakeholder concerns and questions related to sampling and analytical methods for mercury, especially for continuous mercury monitors and sorbent trap methods for future compliance. Advancements were made toward the development of a much simpler dry-based method for measurement of halogens and trace metals. Finally, this research resulted in significant outcomes related to mercury and selenium concentrations in freshwater fish and how it is associated with other elements, thereby potentially impacting health; this has greatly enhanced the understanding of the second-order mechanism of mercury toxicity. The outcomes of this research have been shared with stakeholders in various domestic and international forums, working groups, conferences, educational settings, and published documents, with information available and accessible to those most impacted or interested in timely and current results on toxic metals.
