Chalmers team develops method to reduce levels of mercury in sulfuric acid

Green Car Congress

JULY 10, 2023

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.

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.

Inorganic mercury converted to more toxic and bio-accumulative monomethylmercury in ocean waters, possibly by microbes

APRIL 28, 2011

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.

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.

Duke study finds China’s synthetic natural gas plants will have heavy environmental toll; 2x vehicle GHG if used for fuel

SEPTEMBER 25, 2013

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.

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.

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.

GE Technology Selected for Hydrogen Energy IGCC Project in California

Green Car Congress

OCTOBER 31, 2009

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.

OCTOBER 22, 2009

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.
