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.

Harvard study finds human health risks from Canadian hydroelectric projects

Green Car Congress

In a new study, Harvard University researchers found more than 90% of potential new Canadian hydroelectric projects are likely to increase concentrations of the neurotoxin methylmercury (MeHg) in food webs near indigenous communities. to 10-fold depending on time spent foraging in different environments.
