Surface Decontamination of Mercury (elemental) by DeconGel 1101

by METIS Scientific  (Jun. 29, 2015)

Abstract Surface decontamination efficacy determination of DeconGel™ 1101 on stainless steel, porcelain tile, composite tile (unwaxed), linoleum tile, and concrete surfaces contaminated with mercury (elemental) was performed with Mercury Vapor Analysis Sensor (Mercury Tracker 3000) according to Environmental Protection Agency (EPA) SW-846 ...

Surface Decontamination of Mercury Compounds (Mercury(II) Oxide (HgO)) by DeconGel 1101

by METIS Scientific  (Jun. 29, 2015)

Abstract Surface decontamination efficacy determination of DeconGel™ 1101 on stainless steel, carbon steel, and concrete surfaces contaminated with mercury compounds (mercury(ll) oxide (HgO)) was performed with ICP-OES (Inductively Coupled Plasma-Optical Emission Spectroscopy) according to Environmental Protection Agency (EPA) SW-846 ...

Influence of in ovo mercury exposure, lake acidity, and other factors on common loon egg and chick quality in Wisconsin

by John Wiley & Sons, Ltd.  (Jun. 11, 2015)

We conducted a field study in Wisconsin to characterize in ovo mercury (Hg) exposure in common loons (Gavia immer). Total Hg mass fractions ranged from 0.17 to 1.23 µg/g wet weight (ww) in eggs collected from nests on lakes representing a wide range of pH (5.0 ‐ 8.1) and were modeled as a function of maternal loon Hg exposure and egg laying ...

Removal of trace mercury (II) from aqueous solution by in situ MnOx combined with poly-aluminum chloride

by IWA Publishing  (Jun. 8, 2015)

Removal of trace mercury from aqueous solution by Mn (hydr)oxides formed in situ during coagulation with poly-aluminum chloride (PAC) (in situ MnOx combined with PAC) was investigated. The efficiency of trace mercury removal was evaluated under the experimental conditions of reaction time, Mn dosage, pH, and temperature. In addition, the ionic ...

Mercury and selenium concentrations in skeletal muscle, liver and regions of the heart and kidney in bearded seals from Alaska

by John Wiley & Sons, Ltd.  (May 27, 2015)

Mean concentrations of total mercury [THg] and selenium [TSe] (mass and molar based) were determined for five regions of the heart and two regions of the kidney of bearded seals (Erignathus barbatus) harvested in Alaska in 2010–2011. Mean [THg] and [TSe] of bearded seal liver and skeletal muscle tissues were used for intertissular comparison. ...

An environmental problem hidden in plain sight? Small Human‐made ponds, emergent insects, and mercury contamination of biota in the Great Plains

by John Wiley & Sons, Ltd.  (May 25, 2015)

Mercury (Hg) contamination of small human‐made ponds and surrounding terrestrial communities may be 1 of the largest unstudied Hg‐pollution problems in the United States. Humans have built millions of small ponds in the Great Plains of the United States, and these ponds have become contaminated with atmospherically deposited mercury. In aquatic ...

Mercury free solutions for autoclave temperature monitoring

by Camlab Limited  (May 22, 2015)

Mercury is a naturally occurring element found in the air, water and soil however exposure to the substance, even in small amounts, can lead to severe health and ecosystem issues. Mercury in products can find it’s way into the environment in all sorts of ways such as manufacturing, spills, recycling and disposal. Due to the health ...

3 Questions: Amanda Giang on controlling Mercury Pollution in India and China

by MIT - Massachusetts Institute of Technology  (Apr. 17, 2015)

Original story at MIT News MIT graduate student studies how a new U.N. treaty could affect mercury emissions from coal power plants in Asia. The Minamata Convention on Mercury, a global treaty ...

Effect of laying sequence on egg mercury in captive zebra finches: An interpretation considering individual variation

by John Wiley & Sons, Ltd.  (Mar. 11, 2015)

Bird eggs are widely used as noninvasive bioindicators for environmental mercury availability. However, previous studies have found varying relationships between laying sequence and egg mercury concentrations. Some studies have reported that the mercury concentration is higher in first‐laid eggs or declines across the laying sequence, whereas ...

Influence of a chlor‐alkali Superfund site on mercury bioaccumulation in periphyton and Low‐trophic level fauna

by John Wiley & Sons, Ltd.  (Mar. 2, 2015)

In Berlin, NH, the Androscoggin River flows adjacent to a former chlor‐alkali facility that is a US EPA Superfund site and source of mercury (Hg) to the river. A study was conducted to determine the fate and bioaccumulation of methylmercury (MeHg) to lower trophic‐level taxa in the river. Surface sediment directly adjacent to the source showed ...
