Mercury is a fascinating fluid metal that exists as liquid at 25 C (0 C= 273 K). This silver
colored d-block heavy metal exhibits noble-gas-like characteristics and solidifies at a …

Mercury pollution poses global human health and environmental risks. Although mercury is
naturally present in the environment, human activities, such as coal burning, have increased …

Mercury (Hg) is emitted to the atmosphere mainly as volatile elemental Hg 0. Oxidation to
water-soluble Hg II plays a major role in Hg deposition to ecosystems. Here, we implement a …

A panel of international experts was convened in Madison, Wisconsin, in 2005, as part of the
8th International Conference on Mercury as a Global Pollutant. Our charge was to address …

Global models of atmospheric mercury generally assume that gas-phase OH and ozone are
the main oxidants converting Hg 0 to Hg II and thus driving mercury deposition to …

The atmosphere is an important transient reservoir of mercury. In addition to its great
capacity, the chemical processes transforming mercury between the elemental and divalent …

Abstract Anthropogenic mercury (Hg (0)) emissions oxidize to gaseous Hg (II) compounds,
before deposition to Earth surface ecosystems. Atmospheric reduction of Hg (II) competes …

We use a global 3‐D model of atmospheric mercury (GEOS‐Chem) to interpret worldwide
observations of total gaseous mercury (TGM) and reactive gaseous mercury (RGM) in terms …

Photoreduction of Hg in natural water plays a crucial role in the production of elemental Hg
and its biogeochemical cycle. Solar irradiation and dissolved organic carbon (DOC) in water …

Semiconductor photocatalytic reduction is a relatively new technique for the removal of
dissolved toxic metal ions from wastewater. In this paper, adsorption and photocatalytic …
