The U.S. EPA has issued a final regulation for control of mercury from coal-fired power plants. An NETL research, development and demonstration program under DOE/Fossil Energy Innovations for Existing Plants is directed toward the improvement of the performance and economics of mercury control from coalfired plants. The current Phase II of the RD&D program emphasizes the evaluation of performan...

Although the adsorption of mercury vapor onto activated carbon is a widely used technology to prevent environmental release, the adsorption mechanism is not clearly understood. In this study, we determined the chemical states of mercury on two kinds of activated carbon using X-ray absorption near-edge spectroscopy (XANES) to elucidate the adsorption mechanism. The adsorption experiments of elem...

During the 1950s, while Japanese researchers were seeking for the cause of a strange and fatal neurologic disease spread in Minamata city, it seemed ludicrous that an element located in the period 6 and group 12 of the periodic table would be to blame. Mercury in its organic form, i.e. methyl mercury, was released from the wastewater of a chemical company; bio-accumulated in fi sh and shellfi s...

multiple sclerosis (ms) is a neurodegenerative and autoimmune disease that it’s molecular etiology and factors involving in its progression remains unknown. in this study for evaluation effect of mercuric on progression of ms we investigated the additive effect of mercuric sulfide on the brain mitochondrial dysfunction in experimental autoimmune encephalomyelitis (eae) model of ms in c57bl/6 mi...

Artisanal and Small-Scale Gold Mining (ASGM) is mining of gold deposits with simple physical chemical characteristics using equipment technology. In 2005, total mercury release in the environment ASGM was more than twice from this sector, around 35% mercury, an annual estimate at 727 tons, becoming largest global resource anthropogenic release. Indonesia, released to estimated 340 metric tons p...

528 nature nanotechnology | VOL 3 | SEPTEMBER 2008 | www.nature.com/naturenanotechnology Interestingly, the nano-selenium material captured five times more mercury than the maximum predicted on the basis of its surface area, indicating significant penetration of mercury into the nanoselenium matrix. This did not occur in the other sorbent materials. Even so, the amount of mercury sequestered wa...

The objective of this study was to determine if proximity to sources of mercury pollution in 1998 were related to autism prevalence in 2002. Autism count data from the Texas Educational Agency and environmental mercury release data from the Environmental Protection Agency were used. We found that for every 1000 pounds of industrial release, there was a corresponding 2.6% increase in autism rate...

Submit Manuscript | http://medcraveonline.com J Dent Health Oral Disord Ther 2015, 2(3): 00052 researched mercury poisoning and identified through his research that silver amalgam fillings in the mouth were a source of mercury vapor. More recently, many studies reported that amalgam may constitute potential toxic hazards to patients through mercury release and absorption, surface corrosion, and...

AIM To estimate the quantity of dental amalgam that Ontario dentists release into waste water. METHODS Information from a self-administered postal survey of Ontario dentists was combined with the results of other experiments on the weight of amalgam restorations and the quantity of amalgam waste that bypasses solids separators in dental offices. Algorithms were developed to compute the quanti...
