Application of Biochar to Stabilize Mercury in Riverbank Sediments and Floodplain Soils from South River, VA under Conditions Relevant to Riverine Environments
(University of Waterloo, 2020-01-07)Disposal of mercury (Hg) containing products related to industrial activities has led to large-scale watershed contamination across the globe, posing long-term risks to human health due to its persistent properties. Hg in ... -
Control of mercury and methylmercury in contaminated sediments using biochars: A long-term microcosm study
(Elsevier, 2018-05-01)The effectiveness of activated carbon and four types of biochar, switchgrass (300 °C and 600 °C), poultry manure (600 °C), and oak (∼700 °C) with respect to mercury (Hg) and methylmercury (MeHg) control was assessed in ... -
Evaluation of mercury stabilization mechanisms by sulfurized biochars determined using X-ray absorption spectroscopy
(Elsevier, 2018-04-05)The application of biochar to treat mercury (Hg) in the environment is being proposed on an increasing basis due to its widespread availability and cost effectiveness. However, the efficiency of Hg removal by biochars is ... -
Mercury Transformation and Release from Contaminated Soil Following Perturbations in Solution Chemistry and Application of Polysulfide
(University of Waterloo, 2018-04-09)Mercury (Hg) is a contaminant of concern due to the very high toxicity and bioaccumulating nature of organic Hg and the persistent leaching of Hg to water bodies from contaminated soils and sediments. The deleterious ... -
Methylmercury Production in Riverbank Sediments of the South River, Virginia (USA) and Assessment of Biochar as a Mercury Treatment Option
(University of Waterloo, 2014-01-24)Mercury (Hg) is a toxic element which bioaccumulates in the food chain when methylated and poses a health risk to the human population mainly through fish consumption. It is released into the environment through both ... -
Performance of Treatment Media for the Stabilization of Mercury under Variable Geochemical Conditions
(University of Waterloo, 2010-10-01)Mercury-contaminated sediments are found in many locations throughout North America and the world. Release of Hg from such sediments and subsequent biological uptake can result in biomagnification in associated ecosystems. ...
