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.

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. The research is published in the ACS journal Environmental Science & Technology. Calder, Amina T.

Science Fiction Short: Hijack

Cars That Think

So IEEE Spectrum is making one of its occasional forays into science fiction, with a short story by Karl Schroeder about the unexpected outcomes from building a computer out of planet Mercury. E In a 2013 study, Sandberg and his colleague Stuart Armstrong suggested deploying automated self-replicating robots on Mercury to build a Dyson swarm.

How to Get a Plug-In Hybrid

Tony Karrer Delicious EVdriven

Conversions are mostly for the Prius, with a few for the Ford Escape/Mercury Mariner hybrid SUVs. We Promote PHEV Conversion Programs: First CalCars in 2004, then a number of aftermarket companies, have converted over 200 cars — at first most were for fleets, but more and more are going to individual owners.

research facilities for scientists from universities, industry, and other laboratories, as well as to ORNL researchers: Building Technologies Research and Integration Center (BTRIC). In the case of ORNL’s SNS, the target is mercury. ORNL operates nine user facilities—i.e., Center for Nanophase Materials Sciences (CNMS).
