Salmon-derived mercury and nutrients in a Lake Ontario spawning stream
Salmon-derived mercury nutrients Lake Ontario spawning stream
2014/5/19
We tested the hypothesis that concentrations of mercury species (Hg) and nutrients (NH4+, NO3-, P, and dissolved organic carbon) in abiotic and biotic components would be altered by the decomposition ...
A comparison of the speciation and fate of mercury in two contaminated coastal marine ecosystems: The Venice Lagoon (Italy) and Lavaca Bay (Texas)
speciation and fate mercury in two contaminated coastal marine ecosystems Venice Lagoon (Italy) Lavaca Bay (Texas)
2014/5/14
We compared the speciation of Hg in two estuaries, Lavaca Bay (Texas) and the Venice Lagoon (Italy). Both are large, shallow embayments that are contaminated by direct discharges from mercury-cell chl...
Effects of Montmorillonite Nanocomposite on Mercury Residues in Growing/Finishing Pigs
Montmorillonite Nanocomposite Mercury Adsorption Residue Pig
2016/4/18
The study was conducted to evaluate the effects of montmorillonite nanocomposite (MNC) on mercury residues in growing/finishing pigs. A total of 96 cross bred pigs (Duroc Landrace large white, 48 barr...
Distribution of particulate, colloidal, and dissolved mercury in San Francisco Bay estuary. 1. Total mercury
particulate colloidal dissolved mercury
2014/5/21
Surface water samples were collected from the San Francisco Bay estuary in September–October 2000 (low flow)
and March 2001 (high flow). Total mercury (Hg) concentrations were measured in...
Distribution of particulate, colloidal, and dissolved mercury in San Francisco Bay estuary. 2. Monomethyl mercury
particulate colloidal dissolved mercury
2014/5/21
The phase speciation and estuarine behavior of monomethyl mercury (MeHg) were determined in surface waters
of the San Francisco Bay estuary in September–October 2000 (low flow) and March 2001 (...

Antagonistic effect of selenium on mercury assimilation by fish populations near Sudbury metal smelters?
selenium on mercury assimilation fish populations near Sudbury metal smelters
2014/6/10
In this study, the concentrations of Se and Hg were determined in perch (Perca flavescens) and walleye (Stizosedion vitreum) muscle from nine lakes that varied in distance (4-204 km) from the metal sm...
Spatio-temporal geochemistry of mercury in waters of the Tapajo′s and Amazon rivers, Brazil
he Tapajo′s Amazon rivers
2014/6/9
Spatial and temporal variations of mercury (Hg) concentrations were monitored in the surface waters from the
lower portion of the Tapajo′s River, the Arapiuns River, its principal tributary, and the ...
Electroreduction of Some Diazine and Triazine Pesticides at the Dropping Mercury Electrode
Electroreduction Diazine Triazine Pesticides Dropping Mercury Electrode
2010/6/27
Electroanalytical methods enable determination of electroactive species in nonhomogeneous systems, as limiting currents are little affected by the presence of solid and colloidal particles. An example...
The Effect of Acetone on Calomel Formation on a Mercury Film Electrode Surface in Chloride Medium
The Effect of Acetone Calomel Formation Mercury Film Electrode Surface Chloride Medium
2010/6/27
In the presence of chloride ions, calomel formation takes place on the mercury thin film electrodes under open-circuit conditions, which leads to high base currents and erratic performance in ASV meas...
Specific Determination of Hydrogen Peroxide With A Catalase Biosensor Based on Mercury Thin Film Electrodes
Specific Determination Hydrogen Peroxide Catalase Biosensor Based Mercury Thin Film Electrodes
2010/6/29
A biosensor for specific determination of hydrogen peroxide was developed using catalase (EC 1.11.1.6) in combination with a mercury film electrode. Catalase was immobilized with gelatine by means of ...
