Unintentional emission sectors: Coal burning, ferrous- and non-ferrous (Au, Cu, Hg, Pb, Zn) metal production, cement production. The fifth and final session of negotiations on the establishment of an international mercury convention—International Negotiating Committee on Mercury (INC5)—is taking place this coming week in Geneva.
A team led by the University of Alberta has confirmed that inorganic mercury (Hg) found worldwide in ocean water is transformed into monomethylmercury (MMHg)—a potent and bio-accumulative neurotoxin—in the seawater. In a 1991 paper discussing concerns with mercury and monomethylmercury, William F. 159-166.
Researchers at Chalmers University of Technology, Sweden, have developed a method that can reduce the levels of mercury in sulfuric acid by more than 90%, even from low levels. It is therefore a worldwide challenge that sulfuric acid often contains one of the most toxic substances: mercury.
Coal-powered synthetic natural gas (SNG) plants being planned in China would produce seven times more greenhouse gas emissions than conventional natural gas plants, and use up to 100 times the water as shale gas production, according to a new study by Duke University researchers published in the journal Nature Climate Change.
More forms of mercury can be converted to methylmercury—a form of mercury that can be taken into the food chain and eventually can result in mercury-contaminated fish—than previously thought, according to a study led by a team of researchers from Oak Ridge National Laboratory (ORNL) published in Nature Geoscience.
The TCEP would integrate coal gasification, combined-cycle power generation, CO 2 capture, and. Whiting will be the first in the Permian to purchase CO 2 from a power project that will be produced through the coal-gasification process. urea production. CO 2 capture and shipment via pipeline shown at top. Click to enlarge.
The TRI program collects information on certain toxic chemical releases to the air, water and land, as well as information on waste management and pollution prevention activities by facilities across the country. Among the HAPs showing decline were hydrochloric acid and mercury. air, water or land), an 8% increase from 2010.
IGCC plants gasify solid fuels into syngas, which then is used by a gas turbine combined-cycle system to generate electricity, providing a cleaner, economical coal-to-power option. The technology proposed for the Hydrogen Energy California plant would convert petroleum coke, coal or a combination of each into syngas.
A coal plant in South Texas will shut down and convert to a solar + battery electricity generation facility, with the help of a $1.4 SMECI has operated a mine mouth lignite-fired coal plant (named due to its proximity to the mine that supplies it) since 1982. But that coal-fired plant is one of the dirtiest in Texas.
Breathing vanadium-rich aerosols has unknown but potentially adverse health impacts, according to the researchers, who note that the human impacts on the global vanadium cycle parallel impacts on the global cycles for lead and mercury. Vanadium is a trace metal found in many earth materials, including petroleum and coal.
A new report from the National Research Council examines and, when possible, estimates, “hidden” costs of energy production and use—such as the damage air pollution imposes on human health—that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them. cents per kWh.
WHO estimated in 2012 that 26% of childhood deaths and 25% of the total disease burden in children under five could be prevented through the reduction of environmental risks such as air pollution, unsafe water, sanitation and inadequate hygiene or chemicals. Globally, road traffic injuries killed 135,000 children under 15 years in 2012.
Continuing substitution of gas for coal (and in some instances for oil) will remain an effective short- and middle-term decarbonization measure and an economic boon only insofar as methane leakage from production and transport is held to low levels and drinking water is not adversely impacted, PVCAST noted.
Compared with burning coal, natural gas emits about half the carbon dioxide and substantially less soot, mercury and sulfur. Natural gas must be developed with safeguards to reduce impacts on water, air quality, land, nearby communities and ecosystems. —Mark Zoback, a professor of geophysics and NGI’s director.
