This book was released on 2014-07-23 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mercury in soils, surface water, and groundwater at the William J. Hughes Technical Center , Atlantic County, New Jersey, has been found at levels that exceed established background concentrations in Coastal Plain waters, and, in some cases, New Jersey State standards for mercury in various media. As of 2012, it is not known whether this mercury is part of regional mercury contamination or whether it is related to former military activities. Regionally, groundwater sup-plying about 700 domestic wells in the New Jersey Coastal Plain is contaminated with mercury that appears to be derived from anthropogenic inputs, such as agricultural pesticide use and atmospheric deposition. High levels of mercury occasion-ally are found in Coastal Plain soils, but disturbance during residential development on former agricultural land is thought to have mobilized any mercury applied during farming, a hypothesis borne out by experiments leaching mercury from soils. In the unsewered residential areas with mercury-contam-inated groundwater, septic-system effluent is believed to create reducing conditions in which mercury sorbed to subsoils is mobilized to groundwater.

Download or read book Environmental Chemistry and Toxicology of Mercury written by Guangliang Liu and published by John Wiley & Sons. This book was released on 2011-11-07 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the fundamentals, recent developments, and future research needs for critical mercury transformation and transport processes, as well as the experimental methods that have been employed in recent studies. The coverage discusses the environmental behavior and toxicological effects of mercury on organisms, including humans, and provides case studies at the end of each chapter. Bringing together information normally spread across several books, this text is unique in covering the entire mercury cycle and providing a baseline for what is known and what uncertainties remain in respect to mercury cycling.

This book was released on 2010-08 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Report on how mercury (Hg) was examined in top-predator fish, bed sediment, and water from streams that spanned regional and national gradients of Hg source strength and other factors thought to influence methylmercury bioaccum. Sampled settings include stream basins that were agr¿l, urbanized, undeveloped, and mined. Predator fish were targeted for collection, and composited samples of fish were analyzed for total Hg (THg), as most of the Hg found in fish tissue is MeHg. Samples of bed sediment and stream water were analyzed for THg, MeHg, and characteristics thought to affect Hg methylation, such as loss-on-ignition and acid-volatile sulfide in bed sediment, and pH, dissolved organic carbon, and dissolved sulfate in water.

Book excerpt: 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 properties of Hg pose challenges for remediation as point source contamination can expand over time to affect much wider areas. Saturated, flow-through column experiments were conducted with riverbank sediment and floodplain soil collected from a contaminated reach of the South River near Waynesboro, VA. In one experiment, the composition of input solutions was varied to observe relationships among mobilized Hg, aqueous parameters and effluent constituents and identify dominant mechanisms and controls on Hg transport. Effluent Hg concentrations increased and remained elevated when a higher pH and alkalinity solution was input to the column. Effluent Hg and DOC concentrations were generally positively correlated. Increased effluent Hg concentrations broadly coincided with increased effluent iron (Fe) and manganese (Mn) concentrations and redox (Eh) minima. The lowest effluent Hg concentrations were observed upon decreasing the input solution pH from ~8.7 to ~6, whereas an increase in input pH from ~6 to ~12 coincided with the highest effluent Hg concentrations along with spikes in effluent Fe, Mn and DOC concentrations. Saturated flow-through column experiments with floodplain soil were conducted under both aerobic and anaerobic environments. Greater concentrations of effluent Hg were observed from the column operated in an aerobic environment as opposed to in an anaerobic environment. Two distinct effluent Hg concentration maxima were observed from the aerobic column with increased Hg concentrations observed together with a relatively high Eh (490 mV compared to average Eh of 360 mV) and low Fe and Mn concentrations, whereas the latter and greater Hg maximum broadly coincided with a sharp decrease in Eh (85 mV) and increased effluent Fe and Mn concentrations. The maximum effluent Hg concentration from the anaerobic column also broadly coincided with an increase in effluent Fe and Mn and a minimum Eh but the Hg release was of a much lower magnitude than from the aerobic column. Despite higher total effluent Hg concentrations from the aerobic column, methylmercury (MeHg) concentrations were consistently higher from the anaerobic column. A potassium polysulfide (KPS) solution (1 mM S) was applied to a fully-saturated, flow-through column of floodplain soil for approximately 10 pore volumes (PVs) under anaerobic conditions to assess the potential for polysulfide to stabilize Hg. Effluent Hg concentrations were very high during the application of the KPS solution and remained elevated above the control for the remainder of the experiment after the KPS application ceased; most other parameters were similar in the KPS and control column effluents for the duration of the experiment. An increase in effluent Hg from the KPS column was observed post-KPS application that broadly coincided with a decrease in Eh and increased effluent Fe and Mn. The relationship between increased Hg, Mn and Fe and decreased Eh was also observed in the control column, but the magnitude of Hg release was lower than from the KPS column. XANES sulfur spectra collected from the KPS-treated soil and the control were similar indicating that there was not an apparent change in solid-phase sulfur in the KPS-treated soil compared to the control soil. Dissolution of HgS and formation of highly mobile HgSx2- was likely the dominant mechanism for the Hg release. In situ immobilization of Hg in the floodplain soil was not achieved with the flow-through application of a polysulfide solution; contrary to past studies where immobilization was achieved by in situ formation of HgS via polysulfide application to elemental Hg0 in a glass bead medium.
