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.

The canary box “is a very logical engineering solution to a problem,” says Alan Mantooth , an IEEE Fellow and a professor of electrical engineering at the University of Arkansas. Scientists have been “ radiation hardening ” electronics—designing them to function in a radioactive environment—since the 1960s.

The Frasch process can be tremendously damaging to the surrounding environment and mineworkers’ health. The minerals that contain sulfur often also tend to contain toxic metals like mercury, arsenic, and thallium.
