arsenic is an essential trace element
Many of its compounds are highly toxic. Arsenic toxicity is often the result of the inhibition of certain enzymes, commonly those pertinent to metabolism; specifically, it replaces phosphorus is certain reactions, which can prevent the reaction products from functioning appropriately. This can lead to cellular death, which may in turn leads to tissue death and [[necrosis]], and, if left untreated, death.

While chronic exposure to arsenic can cause several types of cancer, such as bladder and skin, it is also used as an anticancer agent for others, such as acute promyelocytic leukemia. Also,

Cacodylic acid (AsOH(CH<sub>3</sub>)<sub>2</sub>), an organic form of arsenic, is a defoliant and was used in the Vietnam War under the name Agent Blue. In the United States, it is sometimes sprayed on cotton fields, where it causes the plants to desiccate, making harvesting of cotton bolls easier. Cacodylic acid is also the primary excreted metabolic product of arsenic in humans.

[[Oklahoma State University]] veterinary professor Dr. Billy Clay testified that the amount of arsenic used in animal agriculture is insignificant compared to what’s already in the environment. “Arsenic is very common in nature,” Clay said. “It's everywhere.”<ref>http://www.consumerfreedom.com/news_detail.cfm/headline/3379</ref>

==Arsenic as an essential trace element==
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.

: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.

: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.

Serum arsenic concentrations in hemodialysis patients in comparison to healthy controls] - Biol Trace Elem Res. 1993 Apr;37(1):27-38.
