Study the sources of mercury vapor in atmosphere as a threatening factor for human health and bio-filtering methods for removal of toxic pollution

摘要

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.
