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 ... -
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 ... -
Passive In Situ Treatment of Acidic and Neutral Mine Drainage: Field and Laboratory Investigations
(University of Waterloo, 2009-12-16)Water quality degradation is the foremost environmental issue faced by the mining industry. Negative impacts on water quality are commonly associated with unmitigated drainage emanating from sulfide-bearing mine waste ... -
Removal of Arsenic and Metals from Mine-impacted Groundwater Using Organic Carbon and Zero-valent Iron in Passive Remediation Systems
(University of Waterloo, 2020-09-21)Arsenic (As) is a wide-spread contaminant, often encountered in drainage associated with Au mining. The oxidation state controls the mobility and toxicity of As in water. Passive remediation is a potential management ...
