The results from the few studies that have provided a direct comparison of these two compounds have been reviewed recently by Magos (2003), who concluded that a) Hg clears from the body faster after the administration of ethylmercury than after the administration of MeHg; b) the brain-to-blood Hg concentration ratio established for MeHg will overestimate Hg in the brain after exposure to ethylmercury; and c) because ethylmercury decomposes faster than MeHg, the risk of brain damage is less for ethylmercury than for MeHg.
