Fluorescence probe for mercury(II) based on the aqueous synthesis of CdTe quantum dots stabilized with 2-mercaptoetanosulfonate

17-Mar-2017 | M. C. B. S. M. Montenegro; Ana Paula Silveira Paim; S.Sofia M. Rodrigues; David Ribeiro; Gustavo C. S. de Souza; Joa ..., New Journal of Chemistry, 2017

The manipulation of the QDs surface chemistry by adjusting the nanocrystal size, morphology and surface capping ligands plays a crucial role on the selectivity and sensitivity exhibited by the QDs towards a given target analyte. In this work, a novel aqueous synthesis of CdTe QDs capped with a ...

Seasonal and Annual Variations in Atmospheric Hg and Pb Isotopes in Xi’an, China

16-Mar-2017 | Hongmei Xu; Jeroen E. Sonke; Benjamin Guinot; Xuewu Fu; Ruoyu Sun; Aurélie Lanzanova; Frédéric Candaudap; Zhenxing S ..., Environmental Science & Technology, 2017

We present a 3-year time series of lead (Pb) and mercury (Hg) concentrations and isotope signatures in total suspended particulate (TSP) matter and as total gaseous Hg (TGM) in Xi’an, Northwestern China. Mean concentrations of TSP (299 ± 120 μg m–3), PbTSP (0.33 ± 0.15 μg m–3) and HgTSP (0.64 ± ...

Thermodynamic Modeling of the Solubility and Chemical Speciation of Mercury and Methylmercury Driven by Organic Thiols and Micromolar Sulfide Concentrations in Boreal Wetland Soils

15-Mar-2017 | Van Liem-Nguyen; Ulf Skyllberg; Erik Björn, Environmental Science & Technology, 2017

Boreal wetlands have been identified as environments in which inorganic divalent mercury (HgII) is transformed to methylmercury (MeHg) by anaerobic microbes. In order to understand this transformation and the mobility and transport of HgII and MeHg, factors and conditions in control of the ...

IJERPH, Vol. 14, Pages 302: Mercury Levels in Human Hair and Farmed Fish near Artisanal and Small-Scale Gold Mining Communities in the Madre de Dios River Basin, Peru

14-Mar-2017 | Langeland, Aubrey L.; Hardin, Rebecca D.; Neitzel, Richard L., International Journal of Environmental Research and Public Health, 2017

Artisanal and small-scale gold mining (ASGM) has been an important source of income for communities in the Madre de Dios River Basin in Peru for hundreds of years. However, in recent decades, the scale of ASGM activities in the region has increased dramatically, and exposures to a variety of ...

Determination of Mercury (II) in water at sub-nanomolar levels by Laser Ablation - ICPMS analysis of screen printed electrodes used as a portable voltammetric preconcentration system

09-Mar-2017 | Zuriñe Abrego; Nora Unceta; Alicia Sánchez; Alberto Gómez-Caballero; Luis Maria Berrio-Ochoa; M. Aranzazu Goicolea; ..., Analyst, 2017

Environmental pollution by mercury in ambient water samples is a recognized problem worldwide. Sample preservation and transport to the laboratory lead to uncertain analytical results. This study outlines the development of a procedure for on-site electrodeposition of mercury from water samples ...

IJERPH, Vol. 14, Pages 277: Metal Concentrations in Newcomer Women and Environmental Exposures: A Scoping Review

08-Mar-2017 | Chen, Shirley X.; Wiseman, Clare L. S.; Chakravartty, Dolon ; Cole, Donald C., International Journal of Environmental Research and Public Health, 2017

Newcomer women from developing countries are recognized to be at risk for elevated exposures to environmental contaminants and associated negative health effects. As such, data on exposure sources and contaminant body burden concentrations is critical in the development of effective public health ...

Direct analysis of gaseous mercury in ambient air by gas to particle conversion-gas exchange ICPMS

02-Mar-2017 | Masaki Ohata; Kohei Nishiguchi, Journal of Analytical Atomic Spectrometry, 2017

The direct analysis of gaseous mercury (Hg) at the concentration level of a few ng m-3 in ambient air was world-first achieved by gas to particle conversion-gas exchange technique coupled with inductively coupled plasma mass spectrometry (ICPMS). The gaseous Hg was converted to mercury oxide ...
