Biochar is a solid material obtained from the pyrolytic carbonization of biomass in an oxygen-
free/limited environment. Sulfur-containing biochar has a wide range of applications, such …

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 …

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 …

It was discovered in 1995 that, during the spring time, unexpectedly low concentrations of
gaseous elemental mercury (GEM) occurred in the Arctic air. This was surprising for a …

Sulfur-modified pine-needle biochar (BC–S) was produced for the removal of Hg (II) in
aqueous media via post-pyrolysis S stream exposure. Fourier-transform infrared …

Chemical looping combustion (CLC) of coal for carbon capture utilization and storage is an
effective technology to reduce carbon emission due to smaller energy penalty and inherent …

A complex absorbent containing urea and KMnO4 was used to investigate simultaneous
removal of SO2, NO and Hg0 from flue gas. By focusing on NO, SO2 and Hg0 removal …

Elemental mercury (Hg 0) has different behavior in the environment compared to other
pollutants due to its unique properties. It can remain in the atmosphere for long periods of …

Mercury in the Arctic is an important environmental and human health issue. The reliance of
Northern Peoples on traditional foods, such as marine mammals, for subsistence means that …
