In January, 1997, David Nierenberg was a physician at Dartmouth‐Hitchcock Medical Center, specializing in toxicology. Chemist Karen Wetterhahn was placed in his care. When she arrived at the hospital, Karen was slurring her speech and having difficulty balancing and with coordination. What David soon learned was that her symptoms were all due to a few tiny drops of a compound called dimethylmercury. Today’s episode focuses on two lab accidents that had a profound impact on research communities, and that inspired changes that have likely saved the lives of scientists and other workers since. The first story is that of Karen Wetterhahn who, in the 1990s was a professor of chemistry at Dartmouth College whose lab focused on heavy metal toxicity. The other story is about fatal prion protein exposures in France that led to a temporary moratorium in 2021.
