:Despite Arsenic’s reputation as a highly toxic substance, this element may actually be necessary for good health. Studies of animals such as chickens, rats, goats and pigs show that it is necessary for proper growth, development and reproduction. In these studies, the main symptom of not getting enough arsenic was retarded growth and development.<ref> [http://www.mii.org/periodic/LifeElement.html The Role of Elements in Life Processes | Mineral Information Institute]</ref>

:Despite its notoriety as a deadly poison, arsenic is an essential trace element for some animals, and maybe even for humans, although the necessary intake may be as low as 0.01 mg/day.<ref> [http://www.lenntech.com/periodic/elements/as.htm#Health%20effects%20of%20arsenic#ixzz1NrfnT6IU Arsenic (As) - Chemical properties, Health and Environmental effects]</ref>

:Desirable arsenic concentrations in the body seem to be reasonable. This consideration results in the conclusion that arsenic could play an essential role in human health. Thus, reference arsenic concentrations in different human tissues and body fluids should be established in order to recognize not only arsenic intoxication, but also arsenic deficiency.<ref> [http://www.ncbi.nlm.nih.gov/pubmed/7682827 Essential trace elements in humans.
