  • Impact of marine mercury cycling on coastal atmospheric mercury concentrations in the North- and Baltic Sea region

    Bieser, Johannes; Schrum, Corinna (2016)
    Projects: EC | GMOS (265113)
    Abstract The cycling of mercury between ocean and atmosphere is an important part of the global Hg cycle. Here we study the regional contribution of the air-sea exchange in the North- and Baltic Sea region. We use a newly developed coupled regional chemistry transport modeling (CTM) system to determine the flux between atmosphere and ocean based on the meteorological model COSMO-CLM, the ocean-ecosystem model ECOSMO, the atmospheric CTM CMAQ and a newly developed module for mercury partitioni...

    Mercury distribution and transport in the North Atlantic Ocean along the GEOTRACES-GA01 transect

    D. Cossa; L.-E. Heimbürger; F. F. Pérez; M. I. García-Ibáñez; M. I. García-Ibáñez; J. E. Sonke; H. Planquette; P. Lherminier; J. Boutorh; M. Cheize; J. L. Menzel Barraqueta; R. Shelley; G. Sarthou (2018)
    Projects: EC | GMOS (265113)
    We report here the results of total mercury (HgT) determinations along the 2014 Geotraces Geovide cruise (GA01 transect) in the North Atlantic Ocean (NA) from Lisbon (Portugal) to the coast of Labrador (Canada). HgT concentrations in unfiltered samples (HgTUNF) were log-normally distributed and ranged between 0.16 and 1.54 pmol L−1, with a geometric mean of 0.51 pmol L−1 for the 535 samples analysed. The dissolved fraction (< 0.45 µm) of HgT (HgTF), determined on 141 s...

    Multi-model study of mercury dispersion in the atmosphere: atmospheric processes and model evaluation

    D&; Travnikov, Oleg; Angot, Hélène; Artaxo, Paulo; Bencardino, Mariantonia; Bieser, Johannes; Dastoor, Ashu; De Simone, Francesco; Diéguez, María del Carmen; Dommergue, Aurélien; Ebinghaus, Ralf; Feng, Xin Bin; Gencarelli, Christian N.; Hedgecock, Ian M.; Magand, Olivier;... (2017)
    Projects: EC | GMOS (265113)
    Current understanding of mercury (Hg) behaviour in the atmosphere contains significant gaps. Some key characteristics of Hg processes including anthropogenic and geogenic emissions, atmospheric chemistry, and air-surface exchange are still poorly known. This study provides a complex analysis of processes governing Hg fate in the atmosphere involving both measurement data from ground-based sites and simulation results of chemical transport models. A variety of long-term measurements of gaseous...

    Atmospheric wet and litterfall mercury deposition at urban and rural sites in China

    Fu, Xuewu; Yang, Xu; Lang, Xiaofang; Zhou, Jun; Zhang, Hui; Yu, Ben; Yan, Haiyu; Lin, Che-Jen; Feng, Xinbin (2016)
    Projects: EC | GMOS (265113)
    Mercury (Hg) concentrations and deposition fluxes in precipitation and litterfall were measured at multiple sites (six rural sites and an urban site) across a broad geographic area in China. The annual deposition fluxes of Hg in precipitation at rural sites and an urban site were 2.0 to 7.2 and 12.6 ± 6.5 µg m−2 yr−1, respectively. Wet deposition fluxes of Hg at rural sites showed a clear regional difference with elevated deposition fluxes in the subtropical zone, followed b...

    Chemical and physical transformations of mercury in the ocean: a review

    N. Batrakova; O. Travnikov; O. Rozovskaya (2014)
    Projects: EC | GMOS (265113)
    Mercury is well known as a dangerous neurotoxin enriched in the environment by human activities. It disperses over the globe, cycling between different environmental media. The ocean plays an important role in the global mercury cycle, acting both as a dispersion medium and as an exposure pathway. In this paper, we review the current knowledge on the major physical and chemical transformations of mercury in the ocean. This review describes the mechanisms and provides ...

    The superstatistical nature and interoccurrence time of atmospheric mercury concentration fluctuations

    Mercury distribution and transport in the North Atlantic Ocean along the GEOTRACES-GA01 transect

    Multi-model study of mercury dispersion in the atmosphere: vertical and interhemispheric distribution of mercury species

    Bieser, Johannes; Slemr, Franz; Ambrose, Jesse; Brenninkmeijer, C.A.; Brooks, Steve; Dastoor, Ashu; DeSimone, Francesco; Ebinghaus, Ralf; Gencarelli, Christian N.; Geyer, Beate; Gratz, Lynne; Hedgecock, Jan M.; Jaffe, Daniel; Kelley, Paul; Lin, Che-Jen;... (2017)
    Projects: EC | GMOS (265113)
    Atmospheric chemistry and transport of mercury play a key role in the global mercury cycle. However, there are still considerable knowledge gaps concerning the fate of mercury in the atmosphere. This is the second part of a model intercomparison study investigating the impact of atmospheric chemistry and emissions on mercury in the atmosphere. While the first study focused on ground-based observations of mercury concentration and deposition, here we investigate the vertical ...

    Sensitivity model study of regional mercury dispersion in the atmosphere

    Gencarelli, Christian N.; Bieser, Johannes; Carbone, Francesco; De Simone, Francesco; Hedgecock, Ian M.; Matthias, Volker; Travnikov, Oleg; Yang, Xin; Pirrone, Nicola (2017)
    Projects: EC | GMOS (265113)
    Atmospheric deposition is the most important pathway by which Hg reaches marine ecosystems, where it can be methylated and enter the base of food chain. The deposition, transport and chemical interactions of atmospheric Hg have been simulated over Europe for the year 2013 in the framework of the Global Mercury Observation System (GMOS) project, performing 14 different model sensitivity tests using two high-resolution three-dimensional chemical transport models (CTMs), varyi...

    Mercury emissions of a coal-fired power plant in Germany

    A. Weigelt; A. Weigelt; F. Slemr; R. Ebinghaus; N. Pirrone; J. Bieser; J. Bieser; J. Bödewadt; G. Esposito; P. F. J. van Velthoven (2016)
    Projects: EC | GMOS (265113)
    Hg ∕ SO2, Hg ∕ CO, NOx ∕ SO2 (NOx being the sum of NO and NO2) emission ratios (ERs) in the plume of the coal-fired power plant (CFPP), Lippendorf, near Leipzig, Germany, were determined within the European Tropospheric Mercury Experiment (ETMEP) aircraft campaign in August 2013. The gaseous oxidized mercury (GOM) fraction of mercury emissions was also assessed. Measured Hg ∕ SO2 and Hg ∕ CO ERs were within the measurement uncertainties consistent with the ratios calculated ...
