Geochemical Characterization and Assessment of Stabilization Mechanisms for Mercury-Contaminated Riverbank Sediments from the South River, Virginia (USA)
(University of Waterloo, 2013-04-29)Elevated concentrations of mercury (Hg) in aquatic systems can be a threat to ecosystems and human health. Mercury-bearing sediment particles from eroding riverbanks can be an ongoing source of bioavailable Hg to aquatic ... -
Integrating Methods for Characterizing the Passive Treatment of Mercury and Selenium in Groundwater and Sediment
(University of Waterloo, 2011-03-16)Standard geochemical analysis methods, such as aqueous geochemistry analysis and mineralogical analysis, frequently are utilized to evaluate the effectiveness of passive treatment systems, though they do not necessarily ... -
Mercury distribution and speciation in biochar particles reacted with contaminated sediment up to 1030days: A synchrotron- based study
(Elsevier, 2019-04-20)A previous long-term microcosm experiment showed mercury (Hg) in the aqueous phase of contaminated sediment was effectively stabilized through the addition of biochar. The present study focuses on the application of ... -
Stabilization of Mercury in River Water and Sediment Using Biochars
(University of Waterloo, 2016-11-29)Mercury (Hg) is a common contaminant in air, oceans, lakes, rivers, soils, and sediments as elemental, inorganic and organic forms. Organic Hg (e.g., methylmercury (MeHg)), which is much more toxic than other forms and can ...
