Arsenic is a moderately abundant element in Earth's crust, and although many arsenic compounds are often considered highly toxic to most life, a wide variety of organoarsenic compounds are produced biologically and various organic and inorganic arsenic compounds are metabolized by numerous organisms.
Arsenic poisoning (or arsenicosis) is a medical condition that occurs due to elevated levels of arsenic in the body. [4] If arsenic poisoning occurs over a brief period of time, symptoms may include vomiting , abdominal pain , encephalopathy , and watery diarrhea that contains blood . [ 1 ]
Research has not been conducted to determine whether small amounts of arsenic may play a role in human metabolism. [17] [18] However, arsenic poisoning occurs in multicellular life if quantities are larger than needed. Arsenic contamination of groundwater is a problem that affects millions of people across the world.
Arsenic is naturally present in the biosphere, with highest concentration in plant roots. Terrestrial plants can contain up to 200 ppm (parts per million) As. [6] [7] [9] Marine organisms (e.g. Annelida and Echinodermata) contain 6-8 ppm. [7] The human body also contains trace As with highest concentrations in the kidneys and liver (up to ~1.5 ...
This has included the enzymology of arsenic biotransformation; the study of human populations in Chile, Inner Mongolia, Romania, Mexico and rural Southwest China as to their body burden of arsenic or mercury; the human metabolism of chelating agents; and biochemical genetics in particular gene transfer in mammalian cells.

Your body uses this mineral for a lot of different functions including blood pressure control as well as muscle contractions. Lots of foods you probably already eat are high in magnesium.
Arsenic is a neurotoxin commonly found concentrated in areas exposed to agricultural runoff, mining, and smelting sites (Martinez-Finley 2011). One of the effects of arsenic ingestion during the development of the nervous system is the inhibition of neurite growth [92] which can occur both in PNS and the CNS. [93]
