Research conducted by the Seychelles Child Development Study an international research consortium consisting of University of Rochester and the Seychelles Ministries of Health and Education, Ulster University in Northern Ireland, and the Karolinska Institute in Sweden has shown that the fatty acids in fish enhance developmental and educational outcomes and may even help protect the developing brain from the harmful effects of mercury. startxref ; Ruiz, C.M. Mercury - What are the potential health effect of mercury? Very high mercury vapor concentrations can quickly cause severe lung damage. Much of this mercury is released into the air; once it falls to earth, it cycles through soils and surface waters, entering streams, lakes, and estuaries. Responsibility for the information and views expressed herein lies entirely with the authors; the funding sources have not been involved. Mercury exists in various forms: elemental (or metallic) and inorganic (to which people may be exposed through their occupation); and organic (e.g., methylmercury, to which people may be exposed through their diet). Peripheral neuropathy from mercury exposure most commonly involves distal latency sensory slowing for short-term exposures, followed by motor slowing for more long-term exposures. Since both factors represent a multiorgan threat, a possible synergism could be exacerbating health injuries. ; Lima, T.R.R. 0000007189 00000 n Mercury and SARS-CoV-2 infection share many similarities in molecular mechanisms of damage, including but not limited to inflammation, oxidative stress and the disruption of calcium signalization [, SARS-CoV-2 enters cells via the angiotensin-converting enzyme 2 (ACE2) receptor, a homolog of angiotensin-converting enzyme (ACE), and during this process, together with the coronavirus, the intact ACE2 or its transmembrane domain is internalized [, COVID-19 has recently been associated with Kawasaki Disease (KD) in several countries, including France, Italy, the USA and the UK [, Mercury and coronavirus also share pathological effects on cognition [, Another interesting issue shared, at least in part, by mercury and SARS-CoV-2 virus is the genetic susceptibility.
