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.

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.

ORNL study identifies more biopathways for formation of toxic methylmercury

Green Car Congress

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.

Study finds heavy-petroleum fuels raising vanadium emissions; human emissions outpacing natural sources by factor of 1.7

Green Car Congress

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. Excessive V in air and water has potential, but poorly documented, consequences for human health.
