WebElemental mercury (‘quicksilver’), when ingested, is poorly absorbed from the gastrointestinal tract and poses few toxic consequences. Metallic mercury, however, is very volatile and vaporizes readily. Mercury vapor, when inhaled, is absorbed efficiently (Berlin et al. 1969) and has a high affinity for the central nervous system (CNS). WebInorganic Hg (2+) can be methylated by certain bacteria and archaea to form methylmercury. Conversely, bacteria also demethylate methylmercury and reduce Hg (2+) to relatively inert Hg (0). Transformations and toxicity occur as a result of mercury interacting with various proteins.
