Volatilization of elemental mercury from fresh blast furnace sludge mixed with basic oxygen furnace sludge under different temperatures

07-Oct-2015 | Corinna Foeldi; Reiner Dohrmann; Tim Mansfeldt, Journal of Environmental Monitoring, 2015

Blast furnace sludge (BFS) is a waste with elevated mercury (Hg) content due to enrichment during the production process of pig iron. To investigate the volatilization potential of Hg, fresh samples of BFS mixed with basic oxygen furnace sludge (BOFS; a residue of gas purification from steel ...


Suitable extraction of soils and sediments for mercury species and determination combined with the cold vapor generation atomic absorption spectrometry technique

04-Oct-2015 | Author(s): Ione L.S. Almeida, Mônica D.R. Oliveira, José B.B. Silva, Nívia M.M. Coelho, Microchemical Journal, 2015

Publication date: January 2016 Source:Microchemical Journal, Volume 124 Author(s): Ione L.S. Almeida, Mônica D.R. Oliveira, José B.B. Silva, Nívia M.M. Coelho This work reports a fast and efficient procedure for mercury species extraction using Universol® as extractor reagent in ...


Enhanced detection of quantum dots labelled protein by simultaneous bismuth electrodeposition into microfluidic channel

30-Sep-2015 | Mariana Medina‐Sánchez, Sandrine Miserere, Miquell Cadevall, Arben Merkoçi, ELECTROPHORESIS, 2015

In this study, we propose an electrochemical immunoassay into a disposable microfluidic platform, using quantum dots (QDs) as labels and their enhanced detection using bismuth as an alternative to mercury electrodes. CdSe@ZnS QDs were used as label to detect human IgG as a model protein and ...


Significant Signal Enhancement of Dielectric Barrier Discharge Plasma Induced Vapor Generation by Using Non-ionic Surfactants for Determination of Mercury and Cadmium by Atomic Fluorescence Spectrometry

30-Sep-2015 | Yixiao Li; Zhenli Zhu; Hongtao Zheng; Lanlan Jin; S. H. Hu, Journal of Analytical Atomic Spectrometry, 2015

Abstract Non-ionic surfactants (NISs) were used to improve the performance of dielectric barrier discharge plasma induced vapor generation (DBD plasma-CVG). The addition of Triton X-114 leads to 5.4 and 5.1 times improvement in the fluorescence signals of DBD plasma-CVG for cadmium and mercury, ...


Surfactant-Free Green Synthesis of Fe3O4 Nanoparticles capped with 3,4-Dihydroxyphenethylcarbamodithioate: Stable Recyclable Magnetic Nanoparticles for Rapid and Efficient Removal of Hg(II) Ions from Water

30-Sep-2015 | Sada Venkateswarlu; Minyoung Yoon, Dalton Transactions, 2015

Mercury is considered as one of the most notorious global pollutants due to its high toxicity and widespread use in industry. Although many materials have been developed for the removal of mercury for water purification, most of these materials are difficult to reuse, which may lead to an ...


Chemical Vapor Generation from Room Temperature Ionic Liquid Using Solid Reductant: Determination of Trace Hg, As and Sb by Atomic Fluorescence Spectrometry

30-Sep-2015 | Xiaodong Wen; Ying Gao; Peng Wu; Zhiqiang Tan; Chengbin Zheng; Xiandeng Hou, Journal of Analytical Atomic Spectrometry, 2015

Generation of volatile hydrides and elemental mercury was accomplished in non-aqueous media by using solid reductant of lithium aluminium tetrahydride (LiAlH4), stannous chloride dehydrate (SnCl2) or tetrahydroborate (THB) as a derivation reagent. Room temperature ionic liquid (RTIL) was used as ...


In This Issue [This Week in PNAS]

29-Sep-2015 | Proceedings of the National Academy of Sciences current issue, 2015

Mercury and marine mammals Northern elephant seals accumulate MeHg from their prey in the North Pacific. Image courtesy of James Harvey (Moss Landing Marine Laboratories, Moss Landing, CA). Methylmercury (MeHg) is a neurotoxin that accumulates in marine food chains, posing a threat to ...


Mercury offloaded in Northern elephant seal hair affects coastal seawater surrounding rookery [Environmental Sciences]

29-Sep-2015 | Jennifer M. Cossaboon; Priya M. Ganguli; A. Russell Flegal, Proceedings of the National Academy of Sciences current issue, 2015

Methylmercury (MeHg) is a potent neurotoxin that is biomagnified approximately 1–10 million-fold in aquatic carnivores such as the Northern elephant seal (Mirounga angustirostris), whose excreta and molted pelage, in turn, constitute a source of environmental MeHg contamination at the base of ...


High Mercury Wet Deposition at a “Clean Air” Site in Puerto Rico

29-Sep-2015 | James B. Shanley; Mark A. Engle; Martha Scholl; David P. Krabbenhoft; Robert Brunette; Mark L. Olson; Mary E. Conroy, Environmental Science & Technology, 2015

Atmospheric mercury deposition measurements are rare in tropical latitudes. Here we report on seven years (April 2005 to April 2012, with gaps) of wet Hg deposition measurements at a tropical wet forest in the Luquillo Mountains, northeastern Puerto Rico, U.S. Despite receiving unpolluted air off ...


Mercury and Selenium Balance in Endangered Saimaa Ringed Seal Depend on Age and Sex

28-Sep-2015 | Merja Lyytikäinen; Juuso Pätynen; Heikki Hyvärinen; Tero Sipilä; Mervi Kunnasranta, Environmental Science & Technology, 2015

The endangered Saimaa ringed seal (Pusa hispida saimensis) is exposed to relatively high concentrations of mercury (Hg) in freshwaters poor in selenium (Se), a known antagonist of Hg. The impact of age and sex on the bioaccumulation of Hg and Se was studied by analyzing liver, muscle, and hair ...
