Michael Aschner, Ph.D., comments on a study that found high concentrations of mercury in ancient bones from Iberia, which researchers believe was caused by exposure to the toxic red pigment made from cinnabar rock. Dr. Aschner is professor of molecular pharmacology, in the Dominick P. Purpura Department of Neuroscience, and of pediatrics, and is the Harold & Muriel Block Chair in Molecular Pharmacology.
