This study provides an analysis of the impact of global climate policies on mercury emissions using the Greenhouse Gas and Air Pollution Interactions and Synergies (GAINS) model in the time horizon up to 2050. The time evolution of mercury emissions is based on projections of energy consumption provided by the Prospective Outlook for the Long term Energy System (POLES) model for a scenario with...
this study is an attempt to evaluate the biomonitoring capabilities of rock oyster, saccostrea cucullata, for mercury (hg) pollution. the oyster and sediment samples were collected from 10 rocky habitats of qeshm and hormoz islands in the persian gulf. the concentration of mercury in the shell and soft tissues of the oysters and sediments were analyzed using an advanced mercury analyzer. biota-...
Mercury is a very toxic element that is widely spread in the atmosphere, lithosphere, and surface water. Concentrated mercury poses serious problems to human health, as bioaccumulation of mercury within the brain and kidneys ultimately leads to neurological diseases. To control mercury pollution and reduce mercury damage to human health, sensitive determination of mercury is important. This art...
The present paper falls within the trend of research into interactions between various pollutants emitted anthropogenically into the environment and focuses on mercury and styrofoam debris. The study covers part of the Southern Baltic's drainage area. Apart from styrofoam and beach sand, the research involved mosses, which are bioindicators of atmospheric metal pollution. The research has shown...
this paper presents the levels of total mercury (t-hg) in dorsal muscle, liver and spleen of pike (esox lucius) from anzali lagoon in iran. sampling were carried out from july 2004 to july 2005. in addition 78 samples were collected. t-hg concentration were calculated in relation to biometric factors. t-hg was measured by the leco ama 254 advanced mercury analyzer (usa) a...
To further enhance the efficiency and potential of plants for phytoremediation of mercury pollution, a genetically engineered tobacco to simultaneously express mercury transporter, mercury transporter (MerT) and mercury chelator, polyphosphate (polyP) was constructed by integrating bacterial merT gene in polyphosphate kinase gene (ppk)-transgenic tobacco, and its ability to phytoremediate mercu...

The U.S. Environmental Protection Agency (EPA) performed an Information Collection Request (ICR) in 1999 to gather additional information on the control and emission of mercury from coal-fired power plants. The ICR data indicates that a significant, but highly variable, amount of mercury removal can occur across a power plant’s conventional air pollution control (APC) equipment used for the cap...
