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.

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.

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

Green Car Congress

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. —Robert B.

EPA’s 2011 Toxics Release Inventory shows air pollutants continue to decline, releases of toxic chemicals up

Green Car Congress

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.
