A new mechanism for atmospheric mercury redox chemistry: implications for the global mercury budget

Autor: H. M. Horowitz, D. J. Jacob, Y. Zhang, T. S. Dibble, F. Slemr, H. M. Amos, J. A. Schmidt, E. S. Corbitt, E. A. Marais, E. M. Sunderland

Publikováno v: Atmospheric Chemistry and Physics, Vol 17, Iss 10, Pp 6353-6371 (2017)

Mercury (Hg) is emitted to the atmosphere mainly as volatile elemental Hg0. Oxidation to water-soluble HgII plays a major role in Hg deposition to ecosystems. Here, we implement a new mechanism for atmospheric Hg0 ∕ HgII redox chemistry in the GEOS

Measuring and modeling mercury in the atmosphere: a critical review

Autor: M. S. Gustin, H. M. Amos, J. Huang, M. B. Miller, K. Heidecorn

Publikováno v: Atmospheric Chemistry and Physics, Vol 15, Iss 10, Pp 5697-5713 (2015)

Mercury (Hg) is a global health concern due to its toxicity and ubiquitous presence in the environment. Here we review current methods for measuring the forms of Hg in the atmosphere and models used to interpret these data. There are three operationa

Use of a global model to understand speciated atmospheric mercury observations at five high-elevation sites

Autor: P. Weiss-Penzias, H. M. Amos, N. E. Selin, M. S. Gustin, D. A. Jaffe, D. Obrist, G.-R. Sheu, A. Giang

Publikováno v: Atmospheric Chemistry and Physics, Vol 15, Iss 3, Pp 1161-1173 (2015)

Atmospheric mercury (Hg) measurements using the Tekran® analytical system from five high-elevation sites (1400–3200 m elevation), one in Asia and four in the western US, were compiled over multiple seasons and years, and these data were compared w

Nested-grid simulation of mercury over North America

Publikováno v: Atmospheric Chemistry and Physics, Vol 12, Iss 14, Pp 6095-6111 (2012)

We have developed a new nested-grid mercury (Hg) simulation over North America with a 1/2° latitude by 2/3° longitude horizontal resolution employing the GEOS-Chem global chemical transport model. Emissions, chemistry, deposition, and meteorology a

Gas-particle partitioning of atmospheric Hg(II) and its effect on global mercury deposition

Autor: H. M. Amos, D. J. Jacob, C. D. Holmes, J. A. Fisher, Q. Wang, R. M. Yantosca, E. S. Corbitt, E. Galarneau, A. P. Rutter, M. S. Gustin, A. Steffen, J. J. Schauer, J. A. Graydon, V. L. St. Louis, R. W. Talbot, E. S. Edgerton, Y. Zhang, E. M. Sunderland

Publikováno v: Atmospheric Chemistry and Physics, Vol 12, Iss 1, Pp 591-603 (2012)

Atmospheric deposition of Hg(II) represents a major input of mercury to surface environments. The phase of Hg(II) (gas or particle) has important implications for deposition. We use long-term observations of reactive gaseous mercury (RGM, the gaseous
