Abstract: A
global atmospheric transport model is used to calculate mercury concentrations
in the atmosphere. In this study, a comprehensive analysis was made to describe
the environmental behavior and pollution status of mercury (Hg). The most
important aim in this study is to show mercury pollution sources and to
introduce some new technologies for removing this dangerous material from air.
In this paper, some bio technologies such as bio filtering method and bio
adsorbent such as leaves of trees was introduced. The
capacity and application of biotrickling filters for the removal of mercury
vapor from simulated flue gases was expressed. It was resulted from paper that
the most prominent source of mercury is the east of Asia and the southeast of
Asia. The lowest source is concerned Australia. In this investigation it was
found that activated carbon can be one of the best tools for removal of mercury
vapor. The adsorbent uniquely combines a chelating ligand with an ionizing
surface nano-layer on a mesoporous substrate was the other consequences of this
study which can be as a suitable adsorbent for omitting this pollutant from
atmosphere.
