Influence of chemical speciation and community composition on mercury accumulation by freshwater biofilms

23-Nov-2016 | Perrine Dranguet; Severine Le Faucheur; Claudia Cosio; Vera I Slaveykova, Journal of Environmental Monitoring, 2016

Mercury (Hg) is a pollutant of high concern for aquatic systems due to the biomagnification of its methylated form along the food chain. However, in contrast to other metals, the knowledge of its bioavailable forms for aquatic microorganisms remains challenging, making Hg risk assessment ...

A Method for Seawater Desalination via Squeezing Ionic Hydrogels

23-Nov-2016 | Chi Yu; Yanhong Wang; Xuemei Lang; Shuanshi Fan, Environmental Science & Technology, 2016

In this study, mechanical force applied to squeeze poly(sodium acrylate-co-2-hydroxyethyl methacrylate) hydrogels that contained seawater in order to obtain fresh water. By incorporating ionic monomer sodium acrylate (SA) into hydrogels, the salt rejection was significantly enhanced from 27.62% ...

On the Mechanism of Efficiency of Lead Azide

22-Nov-2016 | Boris Khasainov, Marc Comet, Bernard Veyssiere, Denis Spitzer, Propellants, Explosives, Pyrotechnics, 2016

Abstract The mechanism of superior efficiency of lead azide (LA) in comparison with mercury fulminate (MF) is not understood. Indeed, both primary explosives have quite close detonation velocities and result in a large amount of condensed lead (Pb) and mercury (Hg), respectively. We explore an ...

The Estimated Six-Year Mercury Dry Deposition Across North America

22-Nov-2016 | Leiming Zhang; Zhiyong Wu; Irene Cheng; L. Paige Wright; Mark L. Olson; David A. Gay; Martin R. Risch; Steven Brooks ..., Environmental Science & Technology, 2016

Dry deposition of atmospheric mercury (Hg) to various land covers surrounding 24 sites in North America was estimated for the years 2009 to 2014. Depending on location, multiyear mean annual Hg dry deposition was estimated to range from 5.1 to 23.8 μg m–2 yr–1 to forested canopies, 2.6 to 20.8 μg ...

Sensors, Vol. 16, Pages 1945: Quencher-Free Fluorescence Method for the Detection of Mercury(II) Based on Polymerase-Aided Photoinduced Electron Transfer Strategy

18-Nov-2016 | Liu, Haisheng ; Ma, Linbin ; Ma, Changbei ; Du, Junyan ; Wang, Meilan ; Wang, Kemin, Sensors, 2016

A new quencher-free Hg2+ ion assay method was developed based on polymerase-assisted photoinduced electron transfer (PIET). In this approach, a probe is designed with a mercury ion recognition sequence (MRS) that is composed of two T-rich functional areas separated by a spacer of random bases at ...

Automated Calibration of Atmospheric Oxidized Mercury Measurements

18-Nov-2016 | Seth Lyman; Colleen Jones; Trevor O’Neil; Tanner Allen; Matthieu Miller; Mae Sexauer Gustin; Ashley M. Pierce; Winst ..., Environmental Science & Technology, 2016

The atmosphere is an important reservoir for mercury pollution, and understanding of oxidation processes is essential to elucidating the fate of atmospheric mercury. Several recent studies have shown that a low bias exists in a widely applied method for atmospheric oxidized mercury measurements. ...
