'''Arsenic''' is a [[chemical element]] with an [[atomic number]] of 33, and [[atomic mass]] of approx. 74.92, and many of its compounds are highly toxic. It bears a chemical similarity to [[phosphorus]] which is the cause of some of its toxic effects. The most common [[oxidization state|charges]] for arsenic to possess are -3, +3, and -5.

'''Arsenic''' is a [[chemical element]] with an [[atomic number]] of 33, and [[atomic mass]] of approx. 74.92, and is the 20th most abundant element in the Earth's crust. Many of its compounds are highly toxic. It bears a chemical similarity to [[phosphorus]] which is the cause of some of its toxic effects. The most common [[oxidization state|charges]] for arsenic to possess are -3, +3, and -5.

Arsenic poisoning is the result of the allosteric inhibition of certain enzymes pertinent to metabolism, specifically, it replaces phosphorus is certain reactions, which results in their failing to function appropriately. This leads to cellular death, which in turn leads to tissue death and [[necrosis]], and, if left untreated, death.

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.

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>
