Upper atmosphere facilitates changes that let mercury enter food chain

Green Car Congress

New research shows that the upper troposphere and lower stratosphere work to transform elemental mercury into oxidized mercury, which can easily be deposited into aquatic ecosystems and ultimately enter the food chain. Daniel Jaffe, a science and technology professor at University of Washington Bothell, is coauthor of the paper.

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

Green Car Congress

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.

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

Green Car Congress

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.

QUILL researchers showcasing ionic liquid-based processes for removing mercury from natural gas, capturing CO2

Green Car Congress

Researchers from QUILL —the Queen’s University (Belfast) Ionic Liquid Laboratories—will display a novel process for removing toxic mercury from natural gas using ionic liquids at the Royal Society’s Summer Science Exhibition. It’s also how we tailor?make make ionic liquids to trap carbon dioxide.

University of Alberta Researchers Find That Oil Sands Industry Is Releasing More Pollutants Into Athabasca River System Than Previously Estimated

Green Car Congress

New research from a team at the University of Alberta, Canada, finds that Alberta’s oilsands industry is releasing more pollutants into the Athabasca River, its tributaries and its watershed than previously estimated. The pollutants found include mercury, arsenic, lead and cadmium. Kelly et al.

ORNL Spallation Neutron Source achieves 1.55MW record power to enable more discoveries

Green Car Congress

As an example, earlier this month, ORNL reported that researchers from Yale University used the SNS to study hydrogen atom locations and their effects on iron in a compound similar to those commonly used in industrial catalysts. Credit: Jill Hemman/ORNL, US Dept. The data will also be useful for novel catalyst designs.
